【Precision Involute Profile】Expertly ground to exact involute form standards, ensuring smooth meshing and accurate tooth spacing for spur gears and pinions on your milling machine
【High-Speed Steel (HSS) Construction】Crafted from HSS with hardness reaching 58-62 HRC through precision heat treatment, ensuring exceptional durability, wear resistance, and long service life even under heavy machining conditions
【Precision Involute Tooth Profile】Engineered with standard 14.5° or 20° pressure angle to create accurate involute gear teeth, delivering smooth meshing, reduced noise, and optimal power transmission efficiency
【Cutter Number Identification】Clearly etched with the cutter number (#1 through #8) and corresponding tooth range (e.g., #6 cuts 17-20 teeth) for quick identification and setup in your tool crib
【Versatile Application Range】Ideal for producing spur gears, helical gears, and splines for industrial machinery, automotive components, robotics, DIY projects, and custom gear fabrication
