BAMILL 13-20mm Black Oxide HSS Taper Shank Drill Bit Drilling For Wood Plastic Metal

Features: *Black Oxide 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. *The 135° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not walk or wander . 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. *Application: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.
