3M 7000045315 Mounted Flap Wheel 80 Grit Ceramic Alumina

Product Description

The 3M 7000045315 is a mounted flap wheel designed for precision grinding, blending, and finishing on metal and other hard surfaces. It measures 2.5 inches in diameter with a 1 inch face width, and uses a ceramic alumina abrasive coat on a cloth backing for consistent stock removal. The 1/4 inch shank mounts directly into a die grinder or drill press, making it well suited for use in fabrication shops, maintenance environments, and finishing lines. At 80 grit, this medium-grade wheel delivers efficient material removal while leaving a controlled surface finish. Maximum rated speed is 18,000 RPM.

This mounted flap wheel is used in applications where access is limited and a standard bench grinder or angle grinder cannot reach. Typical uses include deburring weld seams, blending surface irregularities, and finishing inside contours, slots, or bores on metal workpieces. It is commonly installed and operated by machinists, fabricators, maintenance mechanics, and metalworking tradespeople working in production or field repair settings.

Key Features

• Ceramic alumina abrasive delivers durable cutting action and extended wheel life on hard metals
• 80 grit medium grade balances material removal rate with surface finish quality
• Cloth backing provides flexibility for contouring and blending on irregular surfaces
• 1/4 inch shank mounts directly to standard die grinders and rotary tools
• 18,000 RPM maximum speed rating supports high-speed tool operation
• No interleaf construction for direct abrasive contact and consistent cut rate

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive accessory for standard 1/4 inch collet die grinders and compatible rotary tools used in metalworking and fabrication applications.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance mechanics using a die grinder or rotary tool with a 1/4 inch collet. Always confirm the tool's rated RPM meets or exceeds the wheel's 18,000 RPM maximum before mounting. Power down and disconnect the tool from its air or electrical supply before changing wheels. Do not exceed the stated maximum RPM and always inspect the wheel for damage before each use.
