The Duo-Bit Masonry Bits feature a high speed steel shank and carbide tips for durability. From drilling concrete to powering through brickwork, these masonry drill bits are excellent for a variety of heavy duty applications! 1/8″ – 1″ in 3″ and 6″ length
Jobber drill bits are well-named, because they do the job as expected. The basic set contains bits made from High-Speed Steel (HSS) with a black oxide finish. The distinctive Black&Gold set has a special finish to help prevent rust. The Mechanics Stubby set features a reduced length, which means it is less prone to breakage, even under hard use. The Cobalt drill bits are specially made to drill through hard metals, including stainless steel.
Paddle bits, also called spade bits, have a wide, flat blade. They are commonly used by tradesmen such as electricians and plumbers for drilling holes through studs in walls for running wiring or pipes (auger bits and hole saws are also used for this), but they also have a place in the woodshop for drilling on fine woodworking projects. An extension kit is available for the extreme jobs. It includes a 12″ extension shaft, and a bent-hex tool to securely tighten the retaining screws when the paddle bit is installed. (See image.)
Spade bits are used for rough boring in wood. Spade bits are flat, with a centering point and two cutters. The cutters are often equipped with spurs in an attempt to ensure a cleaner hole. Intended for high speed use, they are used with electric hand drills. Spade bits are also sometimes referred to as “paddle bits”. Available in 1/4″ – 1-1/2″.
Aircraft drill bits are long drill bits originally designed for use in the aircraft industry where they often need to drill holes reaching through deep cavities, and then through thin materials. You will find them invaluable for drilling holes in tight spaces, and drilling holes through long or wide pieces of wood.
