sourcing map Tap and Drill Bit Set, 2pcs 8-32 UNC Straight Flute Thread Screw Taps & 2pcs 3.3mm Twist Drill Bits, Uncoated/Roasted Yellow HSS-6542/M35 HSS-CO Tapping Threading Tool Kit

• Tap and Drill Bit Set: 2pcs 8-32 UNC (right hand) thread taps and 2pcs 3.3mm (right hand) drill bit. 6542 (M2) high speed steel tap offers high hardness, good toughness, excellent wear and heat resistance for durability. M35 cobalt high-speed steel drill bit offers improved hardness, wear resistance and cutting performance, as well as higher strength.
• Wide Applications: Thread tap & drill bit kit can create new threads or re-thread damaged or jammed threads. Straight flute tap is suitable for through holes or shallow blind holes. Used 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.
• Features: Threading 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/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, Can provide neat and smooth cuts.
• Finish: Uncoated tap is easy to maintain and repair, great for a wide range of applications. Roasted yellow drill bit effectively removes oxidation on the metal surface, and increases corrosion resistance. Use an appropriate lubricant to reduce friction and heat build-up.
• Tips: Drill holes with a twist drill bit first, then tap with a thread tap. Tapping and drilling 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. Tapping depth should not exceed 1.5 times the diameter of tap.
