BECOLLO 13/64 Inch Cobalt Drill Bit Set, M35 Jobber Length Twist Drill Bits,Suitable for Drilling in Hard Metal, Stainless Steel, Cast Iron,10 Pieces

• Made from cobalt(5%) High Speed Steel , increases the wear and heat resistance of drill bit, the life span of drill bit is prolonged.
• Fully Grinding Processing makes the surface of drill bit smoother, the friction can be reduced and the cutting speed is faster.
• 135° Split Point Design improves cutting speed while easy self-centering, prevent walking and skating across the workpiece surface.
• Perfect suitable for drilling in hard metals such as stainless steel and cast iron, and other softer material are also possible.
• 10pcs of 13/64" cobalt drill bit are packed in a plastic case for easy storage and carrying , manufactured in strict accordance with ANSI B94-11M.

Good tools are prerequisite to the successful execution of a job, BECOLLO provides you with good tools. SPECIFICATIONS: Standard: ANSI B94-11M Angel Point: 135°split point ShankType: straight and round shank Material: M35 cobalt(5%) high speed steel FEATURES: 1.Made from cobalt(5%) High Speed Steel , increases the wear and heat resistance of drill bit, the life span of drill bit is prolonged. 2.Fully Grinding Processing makes the surface of drill bit smoother, the friction can be reduced and the cutting speed is faster. 3.135° Split Point Design improves cutting speed while easy self-centering, prevent walking and skating across the workpiece surface. 4.Perfect suitable for drilling in hard metals such as stainless steel and cast iron, and other softer material are also possible, but don't use on hardened steel, high carbon steel and heat treated steel. INSTRUCTIONS FOR USE: 1.Please make sure that the drill and the workpiece are stable before use. It is strongly recommended to use a drill press when drilling thick metal. 2.To avoid breaking the drill bit when drilling, please keep the drill bit perpendicular to the workpiece. Please adjust the RPM to the lowest when you start drilling metal. 3.The friction between the drill bit and the workpiece will generate a amount of heat when drilling, it is necessary to use coolant liquid during the drilling process. 4.The depth of the drilling should not exceed 1/2 of the flute length of the drill bit, this can brings out the best performance of the bit. WARNING: To avoid injury，the use of shields, guards and wrap around safety goggles is recommended.
