Involute gear cutter M2 NR7 HSS
Involute gear cutter M2 NR7 HSS is a high-performance tool designed for precision cutting of the outer serrations of gears with a module of 2. The NR7 variant is dedicated to machining wheels with a large number of teeth, ensuring compliance with an involute tooth outline and a buttress angle of 20°.
Being made of durable HSS, the cutter is characterized by high wear resistance and long service life in demanding working conditions. The staggered blades reduce vibration during cutting, ensuring high surface quality and minimizing the need for additional finishing. The cutter corresponds to the seventh position in the standard eight-piece NFMa set, guaranteeing compatibility with other modular tools.
- Number NR7 - optimized for gears with a large number of teeth.
- High-quality HSS steel - ensures long-lasting and reliable operation.
- NFMa standard - compatibility with industrial tool sets.
- Staggered blades - improve cutting quality and reduce vibration.
- 20° buttress angle - allows for a correct involute profile.
Involute gear cutter The M2 NR7 HSS is an indispensable tool for precision gear mills in industrial applications and precision mechanics.
