Solid Carbide Drill Bit Size: Drilling diameter: 3.3mm / 0.13"; drilling flute length: 22.5mm / 0.89"; shank diameter: 3.3mm / 0.13"; overall length: 40mm / 1.57"; cutting direction: right hand; hardness: 91HRA. Cutting edge provides accurate hole drilling and no glitches. Using the correct size will ensure precise and accurate drilling results.. Micro-grain Tungsten Carbide: Drill bit is made of micro-grain YG6X/C3/K10 tungsten carbide, which has high hardness, high wear resistance, excellent heat resistance and good bending strength. Carbide tool offers long tool life and faster cutting speeds than other substrates.. Wide Applications: Widely used to effectively drill non-ferrous metal, cast iron, stainless steel, aluminum, copper, alloy steel, plastic, wood, etc.. It has cutting performance and can ensure high work efficiency. Designed with the base substrate, suitable for wide ranges of applications.. Features: Twisted spiral design along its length allows for efficient, clean chip evacuation during drilling, which helps prevent clogging and ensures smooth drilling operations. Regularly clear away the chips and debris that accumulate in the flutes of the drill bit.. Tips: Used in drilling machines, hand drills, machining centers, and CNC lathes. Ensure that the workpiece is securely clamped in place before drilling. Use the appropriate cutting fluid or lubricant to reduce friction and extend drill life. Higher speeds may be suitable for softer materials, while slower speeds are recommended for tougher materials..
