3M 7010363164 Flap Disc 4.5 in 80 Grit Type 29 13300 Rpm

Product Description

The 3M 7010363164 is a coated abrasive flap disc designed for high-pressure metalworking applications where fast stock removal and a blended finish are both required. Built on a Type 29 conical profile, the disc runs at up to 13300 RPM and features alumina zirconia mineral bonded to heavyweight polyester-backed flaps. The alumina zirconia grain, combined with a grinding aid, cuts faster and runs cooler than standard aluminum oxide across all metal types. At 80 grit, this disc handles aggressive material removal while leaving a surface that does not require a separate blending step. Licensed trades and fabrication professionals use this disc to reduce cycle time on demanding metalwork.

This flap disc is suited for structural steel fabrication, heavy equipment repair, pipeline work, and general weld finishing. Typical applications include weld removal, sharp-edge deburring, and beveling on carbon steel, stainless steel, and other ferrous metals. The Type 29 angle grind geometry delivers increased contact area on flat and curved surfaces, making it practical for both bench and field service work. The quick-change design reduces downtime during disc swaps.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide on all metal types
• Type 29 conical profile increases surface contact on flat and contoured workpieces
• Heavyweight polyester-backed flaps extend disc life under high-pressure grinding conditions
• Combines grinding and blending into a single pass, eliminating a secondary finishing step
• Quick-change disc design reduces changeover time during production work
• Rated to 13300 RPM for use with standard 4.5 inch angle grinders

Compatibility

Designed for use with 4.5 inch angle grinders rated at or above 13300 RPM. Suitable for weld removal, sharp-edge work, and beveling on carbon steel, stainless steel, and ferrous metals.

Installation Notes

Mounting and disc changes must be performed with the grinder unplugged or the power source isolated. Verify that the grinder's rated RPM meets or exceeds the disc's 13300 RPM rating before mounting. Wear appropriate PPE including face shield and gloves during installation and operation. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel use.
