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.
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.
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.
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.
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.
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.
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
