M35 cobalt high speed steel drill bits offer improved hardness, wear resistance, and higher strength.
  • Finish Roasted yellow finish on drill bit effectively removes oxidation on the metal surface, and increases its corrosion resistance. Uncoated thread tap is great for a wide range of applications. Use with tapping oil to get higher quality threads and more durable taps. Use an appropriate lubricant to reduce friction and heat build-up.
  • Features Thread Tap Straight flute design, clear threads and no burrs, downward chip removal, fast and precise tapping. Machine tap is used in drill presses, tapping, CNC and milling machines. Not recommended for hand use and electric drill tapping. Twist Drill Bit Spiral flute chip space design to remove chips quickly and cleanly. Provide neat and smooth cuts.
  • Tips Drill holes with a twist drill bit first, then tap with a thread tap. The tapping angle should be 90 degrees vertical and stable. The higher the hardness, the slower the speed. Fast speed with small torque; slow speed with high torque. The tapping depth should not exceed 1.5 times the diameter of the tap.
