Material - M42 steel is a super-hard cobalt high-speed tool steel containing 8% cobalt, with good toughness, high wear resistance, high cutting efficiency, and good hot hardness. Nanoscale gold titanium coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant.
Features - Sharp cutting edge provides fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips, saving time and effort in operation. Chamfered shank design for easier clamping and less slippage during use.
Applications - The straight shank drill bits are widely used for drilling hardened steel, titanium alloy, stainless steel, copper, aluminum, cast iron, and other metal materials. Do not drill quenched and tempered materials.
Notes - Choose the right lubricant can facilitate cutting or cooling, make cutting easier, and improve dimensional accuracy. Please pay attention to the speed adjustment when using the electric drill. The larger the drilling size, the slower the speed requirement.
