High-speed steel knurling wheels, specifically HSS type with 8% cobalt, are high-precision and durable tools designed to perform knurling processes on steel parts.
These wheels are supplied in sets of two, ensuring continuous and efficient operation.
Each wheel has a diameter of 20 mm and a central hole of 6 mm, making them compatible with a wide variety of wheel holders and clamping systems.
The HSS high speed steel used in these wheels contains 8% cobalt, which significantly increases their resistance to wear and their ability to maintain a sharp edge under extreme working conditions.
This type of steel is ideal for working with highly hard materials, allowing the knurling of steel with a resistance of up to 125 kg/mm².
This makes these knurls suitable for demanding industrial applications where the quality and precision of the surface finish is crucial.

Recommendations for use:
Be sure to properly secure the wheels in the wheel holder before starting the process to avoid slipping or misalignment during operation.
Use suitable coolants to reduce the heat generated during the knurling process, which will extend the life of the knurling wheels.
Perform knurling under controlled speed and pressure conditions to avoid overheating and premature wear.
Check the hardness of the material to be worked to ensure that it is within the recommended limits for these wheels (up to 125 kg/mm²).
Perform tests on a sample piece before beginning knurling on the final piece, ensuring the finish meets the desired requirements.

Maintenance recommendations:
Regular Cleaning: Clean the wheels after each use to remove material residue that may affect performance on future jobs.
Periodic Inspection: Check the wheels regularly for signs of wear or damage and replace them if necessary.
Proper Storage: Store the wheels in a dry, protected place to prevent rust or damage from impacts.
