Titanium Coated Straight Shank Twist Drill Bits For Alloy Steel - 7.6Mm

Applications & Features:--- Suitable for drilling stainless steel, aluminum alloy, iron, copper, brass, hard wood, hard plastic, and other metal materials in maintenance departments, machine shops, and other industries. Used on drill presses and bench drills. Selecting the correct lubricant can facilitate cutting or cooling, making cutting easier, improving dimensional accuracy and extending tool life.--- The straight shank twist drill is made of high-speed steel, with high hardness, good toughness, high strength, and wear resistance. Titanium coating has excellent corrosion resistance, greatly improves hardness, wear resistance, and reduces the coefficient of friction. Sharp spiral flutes provide fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips, which saves time and effort in operation.Useful Tips:--- Keep cool and gentle when using. When using a hand drill, pay attention to the speed adjustment. The recommended working speed is . Proper use can greatly extend the working life of twist drill bits. Drill metal with high hardness, the rotational speed should be slower than normal drilling. If there is a problem with chip evacuation, go back in time and remove the chips.
