m1.0 · Disc Type — Grade A 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.
Disc-type for internal gears and hubs — module, pressure angle, tooth count and bore ground to your gear drawing.

The disc-type shaper cutter is the classic solution for internal gears: mounted on the shaper spindle, it reciprocates through the bore and generates teeth where no hob can reach. The GS-303B (module m1.0) is ground to Grade A per GB/T 6081 and DIN 3968, so finishing passes hold tooth profile accuracy and pre-shaving passes leave the consistent stock that shaving requires. Pressure angle, tooth count and bore are ground to your gear specification. M35 cobalt HSS with TiAlN coating keeps the edge stable in production runs across steel gear materials.
The GS-300B disc series covers modules m0.2–m1.2 in Grade A. Tell us your module, pressure angle, tooth count, bore and gear material — or send the gear drawing for a quotation.
GS-303B 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 — internal gears are the disc-type shaper cutter’s home ground. The GS-303B mounts on the shaper spindle and generates teeth by reciprocating through the bore, cutting 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.
Disc-type shaper cutters are made to order: pressure angle, tooth count, bore and hub dimensions are ground to your gear specification rather than stocked as fixed standards. Send the gear drawing — or just the module, pressure angle, tooth count and bore — for a quotation.
