This set includes four commonly used drilling sizes—3/16 in (5mm), 1/4 in (6mm), 5/16 in (8mm), and 3/8 in (10mm)—plus two PH2 bits for driving Phillips screws. The drill bits are filled with cooling wax to help dissipate heat and clear chips; using water (wet drilling) can further extend working life.
FOCSTOL recommends using a corded drill, cordless drill, or benchtop drill. For an electric hand drill, a speed of not less than 2000 RPM is recommended. If you plan to use an angle grinder, you’ll need to install an angle grinder drill chuck.
