CoCud Thread Milling Taps, Metric M3 x 0.5 Thread H2, High Speed Steel Machine 3 Straight Flutes Screw Threading Tool - (Applications: for Tapping Drilling Machine), 2-Pieces

• ★ Thread Tap Size --- Thread size: M3 x 0.5 (right hand); square shank width: 2.3mm / 0.09"; thread length: 15mm / 0.59"; overall length: 51mm / 2"; accuracy: H2; flutes quantity: 3 flutes.
• ★ Wide Application --- For threading through holes or shallow blind 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, 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. Add appropriate tapping oil for higher quality internal threads and more durable taps.
• ★ High Speed Steel --- The high speed steel tool has high hardness, high strength, good toughness, wear resistance, and heat resistance. Only the base substrate, without any additional coatings, good for a wide range of applications.
• ★ Useful Tips --- Machine tap is recommended for use with tap chucks with overload protection. Using a hand or electric drill can easily cause tap to break and is not recommended. Due to speed overload or non-vertical tapping, chipping or breakage may easily occur.

Attributes: * Thread Size: M3 x 0.5 (Right Hand) * Square Shank Width: 2.3mm / 0.09" * Thread Length: 15mm / 0.59" * Overall Length: 51mm / 2" * Accuracy: H2 * Material: High Speed Steel (HSS) * Flutes Quantity: 3 Flutes What Is Included: * 2 Pieces x Thread Milling Taps 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. M1-M3.5 micro taps process wood and soft metals with lower hardness, mainly used in clocks and watches. --- The high speed steel tool has high hardness, high strength, good toughness, wear resistance, and heat resistance. Only the base substrate, without any additional coatings, good for a wide range of applications. The tapping depth should not exceed 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: --- Control speed based on material hardness. 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. Fast speed and low torque; slow speed and high torque. 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.
