uxcell Tap and Drill Bit Set, 1pcs M3 x 0.5 Metric Straight Flute Thread Screw Taps & 1pcs 2.5mm Twist Drill Bits, Titanium Coated HSS-6542 Tapping Threading Tool Kit

Features

• Tap and Drill Bit Set: 1pcs M3 x 0.5 (right hand) metric thread taps and 1pcs 2.5mm (right hand) drill bit. 6542 (M2) high speed steel screw tap & drill bit set offers high hardness, good toughness, excellent wear and heat resistance for durability, and good cutting performance for clean, precise holes.
• 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: The taps and drills set are titanium-plated to improve corrosion resistance, prevent rust and reduce friction, making tapping and drilling smoother. Titanium-coated drills also enhance their hardness and heat resistance for faster drilling. 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.
