CoCud Thread Milling Taps, M5 x 0.8 Metric Thread 1/4" Hex Shank, High Speed Steel Machine Straight Flutes Screw Threading - (Applications: for Tapping Drilling Machine)

• ★ Thread Tap Size --- Thread size: M5 x 0.8; hex shank size: 1/4"; thread length: 22mm / 0.87"; overall length: 62mm / 2.44"; accuracy: H2.
• ★ Wide Application --- For threading through holes or shallow blind holes. Straight flutes design, rapid downward chip removal. Make new female threads or re-thread damaged female threads in stainless steel, ordinary steel, copper, aluminum, iron, alloy steel, plastic.
• ★ Machine Taps --- Machine taps are used in tapping machines, vertical drilling and milling machines. M1-M3.5 micro taps process wood and soft metals with lower hardness, mainly used in clocks and watches. Drill holes with a twist drill before tapping.
• ★ High Speed Steel --- High speed steel screw thread taps are high hardness, high strength, good toughness, wear resistance, and heat resistance. Electroless blackening treatment improves the hardness, wear resistance, and rust resistance.
• ★ Useful Tips --- Add appropriate tapping oil for higher quality internal threads and more durable taps. The tapping angle should be 90 degrees vertical and stable. The higher the hardness, the slower the speed.

Attributes: * Thread Size: M5 x 0.8 (Right Hand) * Hex Shank Size: 1/4" * Thread Length: 22mm / 0.87" * Overall Length: 62mm / 2.44" * Accuracy: H2 * Material: High Speed Steel (HSS) * Finish: Electroless Blackening What Is Included: * 1 Piece x Thread Milling Tap Applications & Features: --- Suitable for threading through holes or shallow holes. 3 straight flutes design, rapid downward chip removal. Make new female threads or re-thread damaged female threads in stainless steel, ordinary steel, copper, aluminum, iron, alloy steel, hard plastic. Machine taps are used in tapping machines, vertical drilling and milling machines. Quick change 1/4-inch hex shank can be used on power tools more easily and securely. M1-M3.5 micro taps process wood and soft metals with lower hardness, mainly used in clocks and watches. --- High speed steel screw thread taps are high hardness, high strength, good toughness, wear resistance, and heat resistance. Electroless blackening treatment improves the hardness, wear resistance, and rust resistance. The tapping depth should not be over 1.5 times the diameter (eg: diameter=6mm (M6), maximum tapping depth=9mm). Drill holes with a twist drill before tapping. The tapping angle should be 90 degrees vertical and stable. Add appropriate tapping oil for higher quality internal threads and more durable taps. Useful Tips: --- Feed rate (recommended): ordinary steel (copper aluminium alloy): 6-15m/min; hard steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min. 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. Use No. 30 motor oil for stainless steel.
