1. Thread cutter size: Metric thread size: M10 x 1.25 (righthand thread); Thread length: 24 mm/0.94 inches; Total length: 79 mm/3.11 inches; Square shank width: 8 mm/0.31 inches; Accuracy: H2. Righthand thread cutting, with clean threads and sharp cutting edges for fast and precise thread cutting. 2. Spiral point and straight grooves: The spiral point tip of the thread cutter helps guide it into the hole and reduces the torque needed. The straight grooves of the threaded cutter remove chips downward. The grooves on the thread cutter make it easy to remove chips and dirt from the hole and machine. 3. Wide Applications: Spiral point thread cutters are for through threads and can be used for thread cutting stainless steel, aluminum, cast iron, alloy steel, ordinary steel, nonferrous metals, hard plastic, etc. Suitable for drills, tapping machines, CNC machines, and milling machines. 4. MATERIAL SURFACE: The 6542 (M2) speed steel thread cutter provides hardness and wear resistance for durability and longevity, as well as good cutting performance for clean, precise holes. The coating improves hardness, corrosion and rust resistance, heat resistance, and reduces friction for smooth thread cutting.
