Solid Carbide Drill Bit, 4.2mm Diameter, AlTiSin Coated K45/P10 Tungsten Carbide Twist Drill Bits - (Applications: for Hardened Steel Stainless Steel Alloy), 1-Piece

Attributes:* Drilling Diameter: 4.2mm / 0.165"* Tool Flute Length: 23mm / 0.91"* Shank Diameter: 4.2mm / 0.165"* Overall Length: 45mm / 1.77"* Material: K45 / P10 Tungsten Carbide* Finish: Nanometer AlTiSin Coated* Maximum Work Hardness: HRC65* Tool Flute Type: Spiral* Shank Type: Straight, RoundWhat Is Included:* 1 Piece x Carbide Drill BitApplications & Features:---The solid carbide drill bit is suitable for drilling high-hardness and difficult-to-machine materials below HRC65, such as alloy steel, stainless steel, tool steel, hardened steel. It is also widely used on aluminum, copper, hard plastic and wood. Use on machining centers, CNC lathes, drill presses and bench drills. The appropriate lubricant can facilitate cutting or cooling, improve dimensional accuracy and extending tool life.--- K45/P10 tungsten carbide is a micro grain tungsten-cobalt alloy with higher hardness, better wear resistance, higher strength, better bending resistance and heat resistance. Provides faster cutting speeds than other substrates and is harder but more brittle. Carbide material with good drilling properties ensures high working efficiency. Nanometer AlTiSin composite coatings greatly increase the hardness, wear resistance and thermal stability. Sharp spiral flutes provide fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips.Useful Tips:--- Drill metal with high hardness, the rotational speed should be slower than normal drilling. Keep cool and gentle when using. Not recommended for use with a hand drill (easy to shake, poor stability). If there is a problem with chip evacuation, go back in time and remove the chips. Be careful and control your CNC speed.
