Worm Hobs
Worm Hobs
Worm Gear hobs are special tools that match the worm shaft with a sharpening allowance. Our Worm Gear Hobs are manufactured from premium-grade HSS materials using advanced CNC technology to ensure high accuracy, smooth cutting performance, and long tool life. Custom geometries, pressure angles, and lead corrections can be developed to suit specific application needs.
All hobs are precisely inspected to maintain consistent tooth profiles and dimensional accuracy during production. Surface treatments and PVD coatings can also be provided to enhance wear resistance and productivity.

Product FAQ’s
Q. Can HSS Worm Hobs be customized for special gear profiles?
Yes, HSS Worm Hobs can be customized for special leads, profiles, and pressure angles. OEM drawings and samples can be followed. Customization ensures perfect gear matching. This is essential for specialized machinery applications.
Q. How does tooth accuracy affect worm gear performance?
High tooth accuracy ensures smooth and precise meshing between the worm and gear.
It reduces vibration, noise, and uneven load distribution during operation.
Improved accuracy increases efficiency, service life, and overall gearbox reliability.
Q. Can HSS Worm Hobs be designed for low backlash gears?
Yes, profile modifications can control backlash. Accurate tooth geometry is essential. Super Tools Corporation designs hobs for controlled backlash applications. This improves positioning accuracy in gear systems.
Q. What materials are worm hobs made from?
Worm hobs are commonly manufactured from high-speed steel (HSS), HSS-E, PM-HSS, or solid carbide. Material selection depends on cutting speed, gear material, and production volume. Premium materials improve wear resistance and tool life.
Q. What is the difference between single-start and multi-start worm hobs?
Single-start worm hobs produce gears with higher reduction ratios and better self-locking properties. Multi-start worm hobs allow faster motion and higher efficiency. The choice depends on torque, speed, and application requirements.
Q. What modules and diameters are available in worm hobs?
Worm hobs are available in a wide range of modules and diameters to suit small to large gear sizes. Both standard and non-standard sizes can be manufactured. Custom ranges support specialized gearbox applications.
Q. How do worm hobs improve gearbox performance?
Accurate worm hobs produce gears with smooth tooth contact and reduced backlash. This improves efficiency, noise reduction, and load distribution. High-quality hobs directly impact gearbox reliability.
