Abrasive Types & Performance Highlights

1. DEERFOS BORA 5 Microcrystalline Ceramic

• Self-Sharpening Ceramic Alumina: Microcrystalline ceramic grain fractures under pressure to continually expose sharp cutting edges under heavy grinding pressure.
• Active Cooling Top Coat: Formulated with a specialized grinding aid coating that reduces friction and interfacial heat, preventing workpiece burning and bluing on heat-sensitive stainless and tool steels.

2. High-Strength Aluminum Oxide (AO)

• Heavy Polyester Backing: High mechanical tear resistance maintains edge stability during contour shaping and flat platen sanding.
• Versatile Multi-Material Sanding: Provides consistent cutting action across mild steel, furniture hardwood, non-ferrous alloys, and composites.

3. Seamless Endless Wool Felt Buffing Belts

• Zero-Vibration Seamless Construction: Continuous ring without joints ensures smooth, chatter-free polishing on delicate knife blades and curved tubing.
• Buffing Compound Carrier: Pairs with green rouge, white compound, or diamond lapping paste for scratch-free optical mirror finishes.

Applications & Usage Recommendations

Engineered for knife makers, fabricators, and metalworkers using 2"x42" grinders. Recommended workflow: shape profiles and grind primary bevels with BORA 5 Ceramic (P40–P120); refine scratch patterns and handle contours with AO belts (P120–P800); achieve high-luster mirror finishes using Wool Felt charged with buffing compound.
