PROKUT GAF8502 CBN Grinding Wheel

The PROKUT GAF8502 is a professional-grade CBN (Cubic Boron Nitride) grinding wheel designed for maintenance of 3/4″ pitch harvester chains. Measuring 125mm x 8mm with an 11.1mm (7/16″) bore, this Australian-made wheel is CNC-machined for precise balance and dimensioning. Unlike traditional wheels, it maintains its profile for its entire service life and requires no dressing or deglazing.

• Application: 3/4″ Pitch Harvester Chains (Standard Hardened Steel).

• Dimensions: 125mm (OD) x 8mm (T) x 11.1mm (Bore).

• Key Benefit: Cooler grinding to preserve cutter temper

PROKUT GAF8502 CBN Grinding Wheel (125mm x 8mm x 11.1mm)

PROKUT GAF8502 CBN Grinding Wheel (125mm x 8mm x 11.1mm) This CBN grinding wheel is a durable alternative to traditional vitrified stones for maintaining 3/4″ harvester chains. It is CNC-machined from a solid steel block to ensure balanced, vibration-free operation and a consistent sharpening geometry.

Technical Characteristics:

• Thermal Management: The CBN material draws heat away from the chain during the grinding process. This protects the metallurgical temper of the cutters and prevents the “blueing” associated with standard stones.

• Fixed Profile: Unlike standard wheels that wear down and change diameter, the steel core of the GAF8502 remains the same size for its entire lifespan. This ensures the 8mm profile stays accurate for consistent gullet shaping.

• No Dressing Required: This is a plated wheel that does not become glazed. You do not need to use dressing bricks or profiling tools to keep the wheel effective.

• Reduced Dust: Because the wheel does not break down during use, there is a significant reduction in abrasive dust in the workshop environment.

Specifications:

• Part Number: GAF8502

• Diameter: 125mm

• Thickness: 8.0mm

• Bore Size: 11.1mm (7/16″)

• Material: High-concentration CBN on a steel core.

• Origin: Made in Australia.

Usage Note: Designed for use with standard hardened steel chains only. Use on Tungsten Carbide-tipped chains will damage the CBN plating.
