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.
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.
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.
High Speed Steel Annular Cutters 2″ with a drill depth of 2″ feature unique teeth geometry, provide clear cutting, fast feed rate, less vibration, smooth hole surface and long tool life. These HSS annular cutters – 2″ 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 – 2″ from penetrating the second layer of material.
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.
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 ThunderTwist’s TriCarb grade tip guarantees longer life with faster penetration due to increased chiseling action. ThunderTwist’s flute design, combined with copper brazing alloy creates the most reliable drill bit on the market. It is made with high quality American chrome-molybdenum nickel steel that is vacuum heat treated, and shot-peened for superior strength under the roughest conditions.
