The Impactech driver bit set contains 21 bits made from S2 modified shock resistant steel for professional performance and durability. These bit’s patented spiral torsion zone absorbs impact and extends bit life. The proprietary precision CNC machined tips provide an excellent fit in fastener recess. Impactech bit have been tested to outperform all leading brands in lifecycle and tip failure testing.
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.
Durable hardened cutting edge for long life in tough materials, including nail-embedded wood. Fully-forged bit for maximum durability. Wide flutes for maximum chip removal and less binding. Aggressive screw-pitch for faster drilling. 5/16″ – 1-1/2″ in 6″ and 18″ length.
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.
TruCut Masonry Bits High quality masonry drill bits with heavy duty carbide tips. These masonry bits will drill through any rock or concrete that needs a hole in it. The Premium quality bits have a hex-shaped shaft to eliminate spinning in the drill chuck. They also achieve a longer life at higher speeds due to “Super H” grade carbide tips.
Jobber Drill Bits are made from high-speed steel, with a 118° angle tip, and a black oxide finish. These bits are in Fractional size. American Wire Size bits are listed separately. Click the Jobbers tab below to see more.
Countersinking screws is a often used method for ensuring a flush surface, without bumps of screwheads getting in the way. These cross-hole countersinks are specially designed so that the trailing edge of the hole makes the cut, and they excel at ejecting chips as they drill. Made of strong steel, they ensure years of precision work. Available in a 9 piece or 4 piece set.
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.
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.
