Front 8

Back 8

Twist bit: designed for wood. If you use it with metal, lubricate it with machine oil.

Front 9

Back 9

Brad-point bit: has a center point to help guide the drill bit to the desired position. It drills a clean hole, like those needed for fine woodworking.

Front 10

Back 10

Forstner bit: drills a smooth, shallow hole. It has a small center spur, so it can drill a nearly flat-bottomed hole. Forstner bits should be used only in a drill press.

Front 11

Back 11

Spade bit: the long point makes it easy to locate the hole exactly where you want it. Start the drill at a slow speed as it enters the wood. If you are not careful, it will leave a splintered exit hole.

Front 12

Back 12

Fly cutter: also called a circle cutter. It should be used only in a drill press.

Front 13

Back 13

Expansion bit: can be adjusted to cut holes up to 3". Should not be used with an electric drill.

Front 14

Back 14

Glass/tile bit: Drills holes in glass and tile; must be used at a slow speed.

Front 15

Back 15

Step bit: has up to 13 diameters on it. The hole gets larger as the bit goes deeper into the wood.

Front 16

Back 16

Screw pilot bit: drills the shank and pilot hole for wood screws. The size of the bit needed is determined by the screw size.

Front 17

Back 17

Countersink bit: drills a neat taper for the head of a wood screw.

Front 18

Back 18

Hole saw: cuts large holes in wood, plastic, and thin metal. It is mounted onto a special arbor with a bit in the middle to guide the saw into the wood in the correct location.

Front 19

Back 19

Multispur bit: bores very clean holes at any angle it should be used only in a drill press.

Back 21

Auger bit: for an electric drill

Front 22

Back 22

Drill gauge: measure the size of a drill bit. Insert the drill into the holes until you find a perfect fit.

Front 23

Back 23

Doweling jig: Centers dowel holes in the end or edge of wood. The jig clamps to the wood and centers itself on the edge.

Front 24

Back 24

Flap wheel sander: converts an electric drill into a flexible sander; as the drill turns, the sandpaper strips conform to the contoured surface of the wood.

Front 25

Back 25

Depth stop: slides onto a bit to stop the bit at a certain depth in the wood.

Front 26

Back 26

Vertical drill stand: converts an electric drill into a small benchtop drill press.

Front 27

Back 27

Precision drill stand: fits onto the drill in place of the chuck. It can drill perfectly perpendicular holes, or it can be set to drill holes at a specific angle.
