Titanium Nitride Coated High Speed Steel Reduced Shank Drill Bits - 14.5Mm

Applications & Features:--- Widely used 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. For use on drill presses and bench drills. Selecting the correct lubricant is beneficial for cutting or cooling. Makes cutting easier, improves dimensional accuracy and extends tool life. Tri-flat on the shank is constructed for tighter clamping and precise drilling.--- The straight shank drill is made of high-speed steel, with high hardness, good toughness, high strength, and high wear resistance. The dual coating of titanium and nitride provides better lubricant application, smoother drilling, and is more durable and corrosion resistant than regular surfaces. 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. Reduced shank drill bits expand the size range capacity of portable drill chucks.Useful Tips:--- Drilling edges with burrs: Reduce the number of holes drilled and check various cutting conditions to ensure proper tool handling. Reduce forward and reverse speed. Use harder aluminum and wood. Select the appropriate cutting parameters. Drill metal with high hardness, the rotational speed should be slower than normal drilling.
