High Speed Steel Straight Flute Thread Milling Tap Threading Tool - M12 X 1.25

Applications & Features:--- Suitable for threading through holes or shallow holes. Straight flutes design, rapid downward chip removal. Straight flute taps are often used for machining short chip materials such as cast iron. 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.--- 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 times the diameter (eg: diameter=, maximum tapping depth=). Drill holes with a twist drill before tapping. The tapping angle should be degrees vertical and stable. Add appropriate tapping oil for higher quality internal threads and more durable taps.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.--- Control speed based on material hardness. 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.
