Thread tap adopts spiral point and straight flute design, with clear threads and no burrs. Screw tap provides downward chip removal, fast and precise tapping, suitable for through-hole threads. Machine tap is used in drill presses, tapping, CNC and milling machines. Not recommended for hand use and electric drill tapping.
Twist drill bit adopts a spiral flute chip space design to remove chips quickly and cleanly. Cutting edges provide neat and smooth cuts. Use an appropriate lubricant (such as cutting fluid or oil) to reduce friction and heat build-up.
6542 (M2) high speed steel tap & drill bit set offers excellent heat resistance and hardness for durability and longevity, and good cutting performance for clean, precise holes. Titanium coated drill and tap sets offer enhanced hardness, corrosion and rust resistance, heat resistance, and reduced friction for smoother, faster drilling and tapping.
Tap and drill bit set is widely for cast iron, aluminum, stainless steel, carbon steel, aluminum alloy, bronze and hard plastics. Use with tapping oil to get higher quality threads and more durable taps. The force must be uniform in tapping operations.
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 (for example, the diameter M5x0.8 about 5mm, the depth should not exceed 7.5mm.)
