COMP Cams POW351915 Cross Buff Abrasive 1.5" Very Fine Grit 10-Pack

The COMP Cams POW351915 Cross Buffs are professional-grade abrasive tools designed for engine porting, polishing, and deburring work. This pack of 10 features a 1.5-inch diameter and very fine grit construction, making them ideal for finishing passes on cylinder heads, intake manifolds, and other performance engine components where a smooth, refined surface is required.

Cross buffs are a staple in any engine builder's toolkit. Their cross-shaped abrasive pad design conforms to contours and port walls, allowing consistent material removal and surface blending that flat or cylindrical tools cannot achieve. The very fine grit is suited for final finishing stages — removing minor tool marks, blending transitions, and bringing surfaces to a smooth finish without aggressive material removal.

Key Features:

• Diameter: 1.5 inches (1-1/2 in.)
• Grit: Very Fine
• Quantity: 10 per pack
• Application: Engine porting, deburring, and surface finishing
• Compatible with the COMP Cams Cross Buff Mandrel (sold separately), which accepts 3/4", 1", and 1.5" cross buffs
• Ideal for cylinder heads, intake ports, exhaust ports, and manifold work

For best results, use with a die grinder or drill at appropriate RPM. Pair with the COMP Cams Cross Buff Mandrel for secure, centered mounting. Complete your porting kit with cross buffs in additional sizes and grits, available separately from COMP Cams.
