Carbide Micro Hobs

Carbide micro hobs are manufactured in accordance with international standards such as ISO, DIN, and AGMA to ensure accuracy and interchangeability. These standards define tooth profile, module or DP, pressure angle, and quality grades. Compliance ensures consistent performance, precision, and global acceptance in gear manufacturing. 

Micro hobs are available with both right-hand and left-hand helix angles, depending on the gear design. Typical helix angles range from 5° to 45° for fine and precision gears. Custom helix angles can also be manufactured as per specific drawing or application requirements. 

Super Tools is a top manufacturer of carbide micro hob cutters in India, known for precision manufacturing and advanced solid carbide expertise. Its micro hobs meet strict export-quality and international gear standards. Global OEMs trust Super Tools for consistent accuracy, surface finish, and tool life. 

Carbide micro hobs are widely used in automotive, electronics, and precision engineering industries for producing fine-pitch gears. They are also essential in medical devices, robotics, and micro-motor manufacturing where high accuracy is critical. These industries benefit from superior surface finish and consistent gear quality. 

Carbide grade selection directly affects micro hob performance by balancing hardness, toughness, and wear resistance for the specific work material. Fine-grain carbide grades improve edge sharpness and dimensional accuracy, while tougher grades reduce chipping in high-speed or interrupted cutting. 

Coating improves tool life in carbide micro hobs by reducing friction and cutting temperatures at the tool–workpiece interface. It increases wear resistance against abrasion and adhesion, protecting the sharp micro cutting edges from premature failure. Advanced coatings also minimize built-up edge formation, ensuring consistent performance and longer service life.
