m1.2 · 20° · Z16 — Grade A Pinion-Type Shaper Cutter
Ground to Grade A per GB/T 6081 and DIN 3968 — the accuracy grade finishing and pre-shaving operations are built on.
M35 high-cobalt substrate holds edge hardness in production shaping, for stable cutting performance heat after heat.
TiAlN coating extends tool life in gear steels; TiCN available where the application calls for it.
Internal or external gears, non-standard modules, pressure angles, tooth counts or modified profiles — ground to your gear drawing.

Unlike gear hobs, which are limited to external gears, a pinion-type shaper cutter generates teeth by reciprocating — making the GS-202B the right tool for internal gears, splines, and gear profiles close to shoulders where a hob cannot reach. The m1.2, 20° pressure angle, Z16 form is ground to Grade A, so finishing passes hold tooth profile accuracy and pre-shaving passes leave the consistent stock that shaving requires. M35 cobalt HSS with TiAlN coating keeps the edge stable in production runs across steel gear materials.
The GS series covers modules m0.2–m2.0 in Grade A. Tell us your module, pressure angle, tooth count and gear material — or send the gear drawing for a custom cutter.
GS-202B gear shaper cutter
Grade A is the highest accuracy grade for shaper cutters under GB/T 6081 and DIN 3968, defining tight tolerances on tooth profile, pitch and runout — the foundation for finishing gears to fine quality grades and for pre-shaving operations where the shaving tool follows the shaped profile.
Yes. As a pinion-type shaper cutter, the GS-202B generates teeth by a reciprocating shaping motion, so it cuts internal gears, splines and external gears — including profiles close to shoulders that gear hobs cannot reach.
TiAlN is the standard coating, suited to most steel gear materials for heat resistance and wear life. TiCN is available where the application calls for lower friction or specific workpiece materials — tell our engineers your gear material and we’ll recommend.
Yes. Beyond the standard GS series (modules m0.2–m2.0, Grade A), we grind custom shaper cutters to your gear drawing — special modules, pressure angles, tooth counts or modified profiles. Send the drawing for a quotation.
