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.
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.
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″.
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.
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.
