Black oxide bits are made to last up to 50% longer than standard high-speed steel bits, offering premium durability and speed, and they are considered to be the best general purpose drill bits on the market.
Drill Bits are constructed by heating HSS bits to 950 degrees Fahrenheit. This creates a black oxide finish that will resist rust and corrosion, and also reduces the friction between the bit and the material, which in turn speeds up the drilling process.
Straight shank allows for firmly holding and accurate centering, fit for standard drill chucks and regular round collet chucks. Must be used and operated at proper RPMs for maximum efficiency
Black oxide drill bits are ideal for a multitude of materials including steel, aluminum, copper, brass, PVC, polycarbonate, acrylic, oak, maple, medium density fiberboard, ABS plastic, nylon, and composite materials.
