5Pcs M2 X 0.4 Spiral Point Tap Ti-Coated And 5Pcs 1.6Mm Drill Bit Roasted Yellow

5pcs Spiral Point Taps:Thread size: M2 x 0.4 (right hand); thread length: 10mm / 0.39"; square shank: 2.4mm / 0.09"; total length: 44mm / 1.73"5pcs Twist Drill Bits:Drill size: 1.6mm (right hand); cutting edge length: 17mm / 0.67"; shank dia.: 1.6mm / 0.06"; total length: 42mm / 1.65"Descriptions: 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. 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 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. Titanium coated tap offers enhanced hardness, corrosion and rust resistance, heat resistance, and reduces friction. Roasted yellow drill bit effectively removes oxidation on the metal surface, and increases corrosion resistance. 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. Machine tap is used on drill presses, tapping/CNC/milling machines. Not recommended for hand use and electric drill tapping. Tips:Drill holes with a twist drill bit first, then tap with a thread tap. The cutting angle should be 90 degrees vertical and stable. Tapping depth should not exceed 1.5 times the diameter of tap.
