Feature

●★ Twist drill size --- Cutting edge diameter: 32 mm/1.26 inch; Shank diameter: 1/2 inch; Cutting edge length: 75 mm/2.95 inch; Total length: 155 mm/6.1 inch; Hardness: HRC65-66; Cutting direction: right hand.
●★Wide Applications --- Ideal for drilling stainless steel, aluminum alloys, cast iron, carbon steel, copper, hardwood and hard plastic. Use on drill presses and bench drills. Reduced shank drills increase the capacity of the size range of portable drill chucks.
●★ Spiral Flutes --- Sharp spiral grooves ensure fast, clean and smooth cuts. The spiral groove simplifies the export of metal shavings, saving time and effort on work. Designed with small pockets to keep coolant close to the cutting edge.
●★ 6542 High Speed Steel --- The twist drill bit is of high hardness, toughness and strength. The black nitride coating has excellent wear resistance, corrosion resistance and high temperature resistance. Allows better lubricant application, smoother drilling.
●★ Useful Notes --- The right lubricant has a positive effect on machining or cooling, increasing the dimensional accuracy and the service life of the devices. Reduction of speed when driving forward and reverse. Use harder aluminium and wood.

APPLICATIONS AND FEATURES:

--- The twist drill bit is made of 6542 high-speed steel with high hardness, good toughness and strength. The black nitride coating has excellent wear resistance, corrosion protection and high temperature resistance. Provides better lubricant application, smoother holes, and is more durable and corrosion resistant than normal silver tone surfaces. Sharp spiral grooves ensure fast, clean and smooth cuts. The spiral groove simplifies the export of metal shavings, saving time and effort on work. Designed with small pockets to keep coolant close to the cutting edge.


Useful Notes:

--- Drill edges with burr: reduce the number of holes drilled and check the different cutting conditions to ensure correct handling of the tool. Reduce forward and reverse speed. Use harder aluminium and wood. When drilling metal with high hardness, the speed should be slower than normal drilling.
