Tungsten Carbide Gear Cutting Tool Blanks
Yatech Materials produces preformed tungsten carbide blanks for gear hobs, power skiving cutters and bevel stick blades — supplied near finished size and ready for precision grinding.
Custom dimensions, grades and designs are tailored to each customer’s requirements.
Advantages of carbide gear cutting tool blanks
- Longer tool life — typically 10–40 times longer than HSS, with improved surface finish on machined gears.
- Ultra-fine grain grades — excellent cutting performance and edge quality for fine-module gears.
- Near-net-shape preforming — blanks supplied close to finished geometry reduce grinding allowance and ensure the cutting accuracy of your gear cutting tools.
- Custom manufacturing — dimensions, tolerances and grades produced to customer drawings.
Carbide Gear Hob Blanks
Bore-type hobs with gashes
Shank-type hobs with gashes
Widely used for gears, gearboxes and a wide range of small to medium module external gears. Rough grinding is offered to produce geometries close to the finished form, reducing your grinding allowance and machining costs.
We can manufacture to customer specifications.
Our carbide hob blanks offer longer tool life, better edge retention and higher productivity.

Power Skiving Blanks
Specialized tools for the production of internal and external gears. They are particularly effective for machining internal gears. Combining the principles of gear hobbing and gear shaping, they enable the machining of high precision gears, splines and other complex tooth forms.
Gear cutting blanks are designed to fit into any CNC machine tool holder, resulting in low investment costs. The cutting edge corresponds to the tooth shape required for the particular gear or spline being produced. Carbide can withstand the high cutting forces of the power skiving process, has a longer life and can be resharpened multiple times to produce more parts.
The process of preforming gear cutting blanks with cemented carbide improves the productivity of gear cutting tool manufacturing. This process improves quality at a lower cost and is an inexpensive, fast and effective alternative to traditional gear cutting methods.

Gear Cutting Tool Blanks FAQs
What are tungsten carbide gear cutting tool blanks?
Tungsten carbide gear cutting tool blanks are preformed, near-finished-size carbide bodies used to manufacture gear hobs, power skiving cutters and bevel stick blades. After precision grinding and coating, they become finished gear cutting tools for gear machining.
Can you produce custom sizes and tolerances?
Yes. Yatech Materials manufactures gear cutting tool blanks to customer drawings, with custom outer diameters, bores, widths and tight tolerances that support smooth, accurate finish grinding.
Which carbide grades are available?
We offer standard and fine-grain tungsten carbide grades with different cobalt contents to match hobbing, shaving and power skiving applications. See our tungsten carbide grades for detailed specifications.
Do you support small orders and fast delivery?
Yes. We support both small-batch and volume orders with fast lead times. For a quote on custom tungsten carbide gear cutting tool blanks, please contact us — our engineers will reply within 24 hours.
