One particular type of reduced-shank drill bits are Silver & Deming (S&D) bits, whose sets run from 33/64″ to 1″ drill body diameter with a standard 1/2″ reduced shank for all. This allows drill presses with 1/2″ chucks to run the larger drills. S&D bits are 6″ in length with a 3″ drilling depth.
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.
The rebar cutter heads require a shank adapter to mount them on. This shank comes in multiple styles, so you can find the proper one to work with your hammer driver. Whether you use SDS-Max, SDS-+,or Spline, these are ready for the job.
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.)
Jobber Drill Bits are made from high-speed steel, with a 118° angle tip, and a black oxide finish. These bits are in American Wire Size. Fractional size bits are listed separately. Click on the Jobbers tag below to see more.
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″.
Our Cobalt High Speed drill bits are made of high speed Cobalt Steel. The Cobalt content adds high abrasion resistance to the already hard working properties if our bits. Heavy web construction and 135 degree Split-Point add to the long life of these bits. Available in sizes 1/32″ – 1/2″.
Made especially for drill presses and milling machines, these Silver & Deming drill bits are 6″ long with a 3″ drilling depth. They all have a 1/2″ shaft.
Made from S2 modified shock resistant steel for professional performance and durability. Featuring a patented spiral torsion zone absorbs impact and extends bit life. Proprietary precision CNC machined tips for excellent fit in fastener recess. Tested to outperform all leading brands in lifecycle and tip failure testing. Made with a high strength industrial magnet for securing your bits.
High Speed Steel Annular Cutters 1″ with a drill depth of 1″ feature unique teeth geometry, provide clear cutting, fast feed rate, less vibration, smooth hole surface and long tool life. These HSS annular cutters – 1″ can be widely used in drilling steel, copper, aluminum, stainless steel and plastic, in either plate or pipe form. HSS Euroboor annular cutters feature teeth geometry which is optimized for use on single layer metal work pieces, ensuring the fastest and best drill performance. The rest material created with the use of these annular cutters is the signature Euroboor slug. The rim on this slug is exactly what prevents our HSS annular cutters – 1″ from penetrating the second layer of material.
