These hobs are used for generating spur and helical gears, involute splines, straight key splines, sprockets, worm wheels, timing pulleys, etc. These are generally supplied with bore keyway, however hobs with end drive slot and shank design are also available. With the help of vast experience, expertise and use of latest multi-axis CNC hob profile grinding machines, customized hob shapes and tooth forms are designed and produced to suit customer specifications. We are the best known gear hob manufacturers.
These gear hob cutters can be either single or multi-start for finishing, pre-shaving and pre-grinding gears with profile features including tooth tip chamfer, protuberance, topping / semi-topping, full radius, tip/root relief, or any other modifications.

Involute spline hobs are used to produce involute splines and serrations. These hobs are generally produced with pressure angles 30°, 37.5° and 45° as per various DIN and ANSI standards. These hobs can be offered with shoulder clearances in single and multi-thread designs.
Involute Spline Hobs have straight sides teeth like a gear hob, and are usually of stub tooth depth. They are made in single or multiple thread designs, with diametral pitches ranged from 2.5/5 to 128/256 and pressure angles of 30°, 37.5°, or 45°.
Worm gear hobs are provided to manufacture precision worm gears. These hobs can be offered in both shank type, as well as bore type designs. These are specific tools that match the worm shaft with sharpening allowance. Both radial and tangential hobs can be offered in single and multi-start designs.
Sprocket hobs are designed and produced for the formation of chain sprocket tooth forms by the gear hob manufacturers in India. Both topping and non-topping hobs can be offered in single and multi-thread designs as per various standards including DIN, BS, ANSI, JIS etc.
These hobs have special curved tooth forms to produce straight key splines on shafts. Spline hobs produce exact tooth forms at given tooth depth. Various profile features including lugs and semi-topping can be incorporated on these hobs
These hobs are offered for various special tooth forms such as timing pulleys, ratchets, chamfering ring gears, etc.
Shanks Hobs are offered for today’s high-speed cutting application. These hobs are mainly used on CNC machines. Shank Hobs can be offered with long cutting rows in single and multi-thread designs.
Special Drive Hobs can be designed and manufactured for any special requirement – from OD and face clamping to clutch key ways with special hubs.
S.S. Tools is one of the top gear hob cutter manufacturers in the world today, catering to the needs of the modern gear manufacturing industry. Our gear hob cutters are precision-engineered yet rugged to deliver good performance in every application. From spur, helical, and worm gears, S.S. Tools can give you reliable and efficient cutting tools for your production process.
Our gear hobs are widely used in production across industries for producing accurate and efficient gear. Some of the critical applications are as follows:
A gear hob cutter from S.S. Tools is a precision tool designed to cut the teeth of gears. The hobbing machine on which it operates revolves the cutter while constantly sculpting the gear’s teeth, producing a highly precise and clean cut.
The S.S. Tools basis of choice between gear hob cutters primarily incorporates the cutter material (HSS or carbide), the coating type, and the module size to match the required gear profile. Gear-machining compatibility must be considered, including spur, helical, and worm gears, for better performance.
Routine servicing of S.S. Tools gear hob cutters includes:
The main difference between gear hob cutters and gear shaper cutters lies in their cutting motion. Gear hob cutters work in continuous rotation throughout the cutting process, whereas gear shaper cutters work using a reciprocating action. Gear hobbing is used to produce external gears at high production; otherwise, gear shaping can also be used on internal gear profiles.
Set up appropriately with S.S. Tools gear hob cutters with a workpiece attached to the machine. Remember proper attire, personal protection gear, gloves, safety glasses, and adequate lubrication to avoid overheating and prematurely wearing the cutter.
