CoCud Metric Hand Threading Tap Set, M3 M4 M5 M6 M8 Thread, Blue Coated Screw Taps Tapping Tools - (Applications: for Thread Repair), 5-Pieces

• ★ Hand Threading Tap Size --- Thread size: M3 x 0.5, M4 x 0.7, M5 x 0.8, M6 x 1, M8 x 1.25 (right hand); overall length: 47mm / 1.85", 53mm / 2.09", 62mm / 2.44", 64mm / 2.52", 67mm / 2.64"
• ★ Wide Applications --- Suitable for tapping through or shallow blind holes. Create new threads or re-thread damaged or jammed threads, such as threads in nuts, threaded inserts, pipes. Used for stainless steel, carbon steel, alloy steel, cast iron, aluminum, brass, plastic.
• ★ Hand Taps --- Straight flutes design, downward chip removal, clear threads. Hand taps are used by tap wrenches. Apply a suitable lubricant helps to prolong the tool life, reduce friction, and improve thread quality. It is a reliable tool for manually creating precise threads.
• ★ High Speed Steel & Blue Coat --- High speed steel screw taps are high hardness, high strength, good toughness, and wear resistance. The blue coating increases hardness, reduces friction and heat, improves lubricity, and protects against rust and corrosion.
• ★ Useful Tips --- Drill holes with a twist drill before tapping, and the tapping angle should be 90 degrees vertical and stable. The higher the hardness, the slower the speed. Always use the correct speed and pressure.

Create new threads or re-thread damaged or jammed threads, such as threads in nuts, threaded inserts, pipes. Used for stainless steel, carbon steel, alloy steel, cast iron, aluminum, brass and hard plastic. --- Straight flutes design, downward chip removal, clear threads. High speed steel screw taps are high hardness, high strength, good toughness, and wear resistance. The blue coating increases hardness, reduces friction and heat, improves lubricity, and protects against rust and corrosion. It is a reliable tool for manually creating precise threads in a variety of materials and applications. --- Hand taps are used by tap wrenches. Apply a suitable lubricant helps to prolong the tool life, reduce friction, and improve thread quality. Always use the correct speed and pressure. Drill holes with a twist drill before tapping, and the tapping angle should be 90 degrees vertical and stable. Useful Tips: --- The higher the hardness, the slower the speed. When tapping plastic, add lubricating coolant. For steel, motor oil is generally used, and vegetable oil is used for high requirements. Apply anti-rust oil for maintenance after use to prolong the service life.
