CoCud Twist Drill Bits, 1.6mm Drilling Diameter, Titanium Coated (HSS-CO) M35 5% Cobalt High Speed Steel - (Applications: for Stainless Steel Alloy Metal), 10-Pieces

• ★ Twist Drill Bit Size --- Drilling diameter: 1.6mm / 0.063"; tool flute length: 20mm / 0.79"; shank diameter: 1.6mm / 0.063"; overall length: 42mm / 1.65"; hardness: HRC64-68; point angle: 118 degree.
• ★ Wide Applications --- 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. Specially designed for stainless steel.
• ★ Spiral Flutes --- 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. Designed with small pockets to keep coolant near the cutting edge.
• ★ M35 5% Cobalt High Speed Steel --- higher hardness and strength, good toughness, wear resistance. Titanium coating has excellent corrosion resistance, greatly improves hardness, wear resistance, and reduces the coefficient of friction.
• ★ Useful Tips --- Use on drill presses and bench drills. The correct lubricant can facilitate cutting or cooling. Keep cool and gentle when using. When using a hand drill, the recommended working speed is 100-1000r/min.

Used on drill presses and bench drills. Selecting the correct lubricant can facilitate cutting or cooling, make cutting easier, and improve dimensional accuracy and extend tool life. --- The straight shank twist drill is made of M35 5% cobalt high-speed steel, with higher hardness and strength, good toughness, 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 100-1000r/min. 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.
