Tap & Drill Bit Set 5-40 UNC Straight Flute Tap And 2.6Mm Drill Bit Ti-Coated

1pcs Thread Tap: Thread Size: 5-40 UNC; Thread Length: 16mm / 0.63"; Square Shank Size: 3mm / 0.12"; Total Length: 50mm / 1.97" 1pcs Twist Drill Bit: Cutting Edge Diameter: 2.6mm / 1/10"; Shank Diameter: 2.6mm / 1/10"; Cutting Edge Length: 25mm / 0.98"; Total Length: 55mm / 2.17" Descriptions: Thread tap adopts straight flute design, with clear threads and no burrs. Right hand thread cutting, downward chip removal, fast and precise tapping, suitable for through holes or shallow blind holes. Machine taps are used in drill presses, tapping, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. 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 tool set offers excellent heat resistance and hardness for durability and longevity, and good cutting performance for clean, precise holes. Gold titanium coating enhances hardness, corrosion and rust resistance, heat resistance, and reduces friction for smoother and faster drilling. Suitable for cast iron, aluminum, stainless steel, carbon steel, aluminum alloy, bronze and hard plastics. 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. The tapping depth should not exceed 1.5 times the diameter of the tap (for example, the diameter M4x0.7 is about 4mm, and the depth should not exceed 6mm.)
