4Pcs Spiral Flute Thread Tap 1/4-20 BSW Machine Taps HSS-CO Uncoated

Specifications: Thread Size: 1/4-20 BSW Tolerance: H2 Thread Length: 24mm / 0.94" Square End Size: 4.5mm / 0.18" Total Length: 68mm / 2.68" Material: M35 Cobalt High-Speed Steel (M35 HSS-CO) Finish: Uncoated Cutting Direction: Right Hand Package Included: 4 x Spiral Flute Thread Taps Descriptions: The spiral flute design ensures smooth chip evacuation, prevents breakage, and enables more efficient tapping. The spiral tip of the tap helps guide it into the hole, reducing the torque required to turn it, and the flutes easily remove chips and debris from the hole and machine. Spiral flute thread taps are suitable for machining blind or deep holes and sticky materials, and can be used for tapping stainless steel, aluminum, cast iron, alloy steel, ordinary steel, non-ferrous metals, hard plastics, etc. Suitable for drilling machines, tapping machines, CNC machine tools and milling machines. Used with tapping oil, you can get more precise threads and more durable taps. Taps are made of M35 cobalt high-speed steel, which has high hardness, good wear resistance, heat resistance, and strong resistance to thermal shock. Uncoated tap is easy to maintain and repair, and great for a wide range of applications. It is recommended to use machine taps with tap chucks with overload protection. It is not recommended for manual use and electric drill tapping to avoid damage caused by uneven force. The tapping angle should be 90 degrees vertical. The harder the material, the slower the drilling speed.
