Common Drills

There’s a good chance you’ve run into some of these drills at some point in your life. They’re all quite useful in your tool box or workshop.

benchtop drill pressBenchtop Drill Press

Also known as: bench drill, portable drill press

Usually mounted to a workbench, this drill press is a smaller variation of the floor drill press. The drive is positioned vertically above an adjustable platform.

It has numerous uses in workshop activities, thanks to the ability to swap out drill bits for other accessories. These can be very powerful and aren’t well-suited for beginners but can be invaluable for veteran craftsmen.

corded drillCorded Drill

This powerful drill draws power from an outlet and can provide higher torque than most other drills although cordless drill technologies have caught up or even surpassed their corded counterparts.

Its pistol grip and variable-sized drills make it a comfortable and useful tool. It works equally well in any task involving wood, plastic, metal, or fiberglass. There’s never a worry about running out of battery life although a good extension cord is necessary.

cordless drillCordless Drill

Also known as: drill driver

Similar in appearance to its corded sibling, cordless drills employ a battery pack to make them more portable. They’re more easy to transport on a tool belt, but have a limited charge, requiring you to carry spare batteries or recharge between uses.

They can easily handle wood, fiberglass, metal, and plastic, but most aren’t powerful enough to be used on concrete or masonry.

floor drill pressFloor Drill Press

Also known as: pedestal drill, pillar drill

These large workshop drills have the ability to add sanding drums or other accessories to expand their function. Floor standing drill presses are larger than their benchtop siblings but are also more portable in some cases.

A pillar extends from the base to the press, lending to its nicknames. If you have the room for a floor standing model, you’ll get better power, more stability, and a larger work area. Used for cutting holes into or through wood, metal, or other material.

hammer drillHammer Drill

Also known as: concrete drill, hammer drill driver

Hammer drills produce a lot of power by using torque from cam plates to slam the drill bit into concrete, stone, or other hard materials. Many models (corded, cordless, even brushless) have the option to switch between hammer, rotary, or combined modes.

While they work best in stoneworking, the ability to switch to rotary mode allows this drill to be used in normal projects.

impact drillImpact Drill

Also known as: impact driver

These stubby drills have a hexagonal socket in place of a normal chuck. Thanks to the percussive action, an impact driver can make quick work of difficult projects.

Automobile work is one of the mainstays for this tool, which does an excellent job at removing various nuts bolts. Its big brother, the impact wrench, is larger and much more powerful. 

rotary hammer drillRotary Hammer Drill

Also known as: combination hammer, masonry hammer, rotary hammer

Used mainly in stoneworking trades, the rotary hammer drill is a sleek powered drill with a secondary grip for better handling. While they normally run on electricity, there have been steam-powered models in the past.

Most rotary drivers have an additional hammering function which piledrives the bit as it rotates, leading to much greater drilling power. What sets them apart from regular hammer drills is the use of a piston instead of cam plates to accelerate only the drill bit.

Other Drills

In addition to the more common drills are a wide variety of more specialized drills. Some of these drill types you might have seen or even used without ever thinking of them as drills.

air angle grinderAir Angle Drill 

Also known as: right angle drill

With the bit set at 90 degrees to the handle, these pneumatic drills function in the same way as their electric counterparts but without the need for electricity.

The positioning of the bit and small profile also allow you to get into tighter spaces where a full-sized drill might not fit.

augerAuger 

Also known as: ground auger, earth auger

While the term auger may be used as a synonym for drill, earth augers are a much larger variant used to bore holes in the ground. There are a wide range of augers out there.

These include one- and two-person models which have a motor mounted above the bit and handles protruding from between them to large bits attached to construction vehicles. The manual versions are used for tapping springs and creating post holes.

beam drillBeam Drill

As the name suggests, a beam drill is used for making holes in large beams. The most famous brand is Swan which has been used for constructing barns and other similar structures for generations. The drill vertically aligned and the base rests directly upon the wood.

With an open spot in the center for viewing the cutting area. Once the bit is lowered and aligned, you straddle the beam and use the two bicycle pedal-style hand cranks on either side to corkscrew the bit into the wood, then simply reverse the process to remove the bit from the hole.

bow drillBow Drill

Also known as: fire drill

Originating from an ancient tool used to start fires, the bow drill has a shaft and movable spindle shaped like a bow. A weight near the base serves as a flywheel. Moving the bow up and down the shaft causes the spindle to turn, creating friction heat.

Although the tool is most often associated with fire making, it has been adapted for use in dentistry and woodworking.

brace drillBrace Drill

A staple in many woodworking shops, thus U-shaped tool can countersink precise holes. The top spindle is used for positioning and holding the drill, while the middle of the U-shape provides a secondary spindle grip for rotating the drill bit.

The offset of the secondary spindle gives better torque and control when it comes to its intended function.

breast drillBreast Drill

Also known as: belly drill, chest drill, knee drill

Similar to a hand drill or eggbeater drill, the breast drill is designed to use your body to increase its force. This drill can be found in blacksmith shops and industrial facilities.

A concave plate at the end allows you to lean on the drill to increase its drilling power. In the past, this drill allowed its user to bore holes in steel, iron, and very hard wood.

CNC drillCNC Drill

Also known as: CNC drill press

CNC (Computer Numerical Control) drilling is used in mass production industries to achieve precise holes quickly. The actual drill is often a multifunction tool capable of drilling, boring, milling, and turning.

Due to its pre-programmed functionality, CNC drills are sometimes fully enclosed units with retractable access and an external computer terminal.

Others have a suspended control panel and variable drill tools attached to an angled turret. These latter models rotate to the proper drill tool, then lower the drill onto the object using a ram.

core drillCore Drill

Also known as: coring drill, annular cutter

When you need to put a large hole into a wall or surface, core drills are the way to go. These cylindrical cutters are often diamond tipped and fit over an auger bit. They leave a solid core or slug in the center.

Coring drills are extremely powerful and require a safety clutch and secondary grip to reduce the risk of injury to the user. They are essentially a large, heavy duty version of a hole saw.

cranial drillCranial Drill

This compact surgical tool has an incredibly long history of use, but the more modern versions have proven much safer, thanks to a special clutch that disengages the drill the moment it touches soft tissue.

These drills may be used for relieving cranial pressure or providing access  to the brain. Versions are available that use pneumatic, manual, and electric power.

spade handle drillD-Handle Drill 

Also known as: spade handle drill

Named for its D-shaped handle, this drill is used in a wide range of occupations where high torque is needed. There are some variations that use an angled drive for drilling at 90 degrees.

Can be used for drilling and mud mixing and where extra control and a secure grip are needed.

dentist drillDentist Drill

Surpassed only by clowns in the realm of childhood terrors, the dental drill is shaped much like a ratcheting wrench, with a long vertical handle and small cylindrical head. The tiny bit protrudes horizontally.

When in use, the slow models spin at 8,000 RPM, while the fast models have an insane 250,000 RPM. The drill sprays water when in use to prevent overheating and help remove debris from the work site.

gimlet drillGimlet Drill

A small form of manual drill, gimlets come in a variety of shapes. They can be used for quickly drilling pilot holes and are incredibly useful in woodworking for starting nail or screw holes.

One variant of the gimlet has a T-shape with a wooden handle and graces many restaurants and kitchens – the corkscrew.

hand eggbeater drillHand Drill

Also known as: eggbeater

Gaining its nickname from its resemblance to an old-fashioned eggbeater, hand drills are not especially powerful and produce rotation via hand crank and gears. Their claim to fame is in their ability to create tiny, precise holes in soft wood or metal that require a delicate touch.

As such, they are treasured tools in woodworking and hobbies such as model building. A more powerful version, the crank drill, is capable of cutting into metal alloys.

horizonal drill pressHorizontal Drill Press

Also known as: horizontal boring machine

This floor-mounted drill has a forward-facing drill bit. The motor assembly is mounted behind the tool on a heavy spring and a cam handle is used to hold the workpiece down on the table when drilling.

Once turned on, a pedal is used to pull the drill assembly forward into the workpiece. This tool is most commonly found in woodworking shops and can be used to drill accurate holes when preparing wood for furniture or similar projects.

mill drillMill Drill

An alternative to milling machines, mill drills are lighter and combine a belt-driven drill press with the same X/Y coordinate functionality of a drill press’s work table. A locking collet helps prevent the cutting tool doesn’t fall off the spindle when exposed to lateral forces.

While milling machines tend to be restricted to industrial use, the smaller mill drill has models appropriate for home use as well as commercial and industrial. As mill drills remove material rather than simply cutting a hole, they are useful in a wide range of construction projects.

mini drillMini Drill

Also known as: jewelry drill, precision drill

These tiny drills somewhat resemble precision screwdrivers. While manual versions are best when control is essential, air powered and electric versions are available as well (including rotary tools such as Dremel).

Due to their smaller bit sizes, mini drills are perfect for hobbies such as jewelry-making and model building.

paper drillPaper Drill 

Also known as: paper drill press

This drill is exactly what it sounds like: a sibling of the drill press designed specifically for drilling precise holes in paper.

Depending upon the model, a paper drill can create one or more holes simultaneously in a stack of paper up to two inches thick (i.e. approximately one ream of printer paper).

post drillPost Drill

Also known as: hand powered drill press

These traditional drills gain their name because they’re best mounted onto posts.

Still used on farms and in some industries, these hand-powered presses can cut through iron but the maximum hole size and depth are limited by the user’s strength and stamina.

push drillPush Drill

Closely resembling a screwdriver with a threaded shaft, the push drill functions by pushing on the handle.

This turns a nut which, in turn, rotates the shaft. Due to its precision, this tool is useful in woodworking, dentistry, and jewelery-making.

radial drillRadial Drill

Also known as: radial arm drill, radial drill press

These drill presses have a geared head that can be repositioned along the length of the arm, allowing you to drill holes in a straight line without having to adjust the object or machine’s position.

They have a wide range of uses in metal and woodworking shops, and have the ability to bore through iron.

ratchet drillRatchet Drill

This manual drill uses a ratchet-driven chuck on a narrow shaft and handle.

They’re excellent for getting into tight spaces, making them useful in a wide range of crafts, hobbies, and spot repairs.

straight air drillStraight Air Drill

These pneumatic drills come in a range of shapes and sizes, from a flashlight-like cylinder to a gun-shape similar to corded drills. The trigger is usually located on the underside, with an air regulator on the top or back.

These drills function just like corded or cordless drills, except they’re safer to use in environments where the drill could come into contact with water, since they don’t rely on electricity to function.

switchdriverTwo-Headed Drill

Also known as: SwitchDriver

The two-headed drill is a relatively new concept which combines a cordless drill with an impact driver. The two heads are located on a rotating chuck which keeps the unused head out of the way while engaging the desired head with the motor,although the battery may not hold up to heavy use until the tool has more time to evolve.

These are excellent tools for those who need both tools at once. This tool is best known by the name of the original model, the SwitchDriver by WORX.
