3M 7000148192 Cubitron Ii 967A 7 Inch 80 Grit Flap Disc

Product Description

The 3M 7000148192 is a Type 29 right-angle flap disc built on the Cubitron II 967A platform and engineered for medium-pressure grinding and surface preparation tasks. At 7 inches in diameter and 80 grit, it uses 3M Precision-Shaped Grain — a triangular ceramic abrasive mineral that fractures along consistent planes to continuously expose sharp cutting edges. The result is a fast, aggressive cut rate that holds up across the life of the disc without the stepwise dulling typical of conventional aluminum oxide flap discs. Weighing 0.54 pounds, it mounts on standard right-angle grinders used by fabricators, welders, and metalworkers.

This disc is well-suited to flat and contoured surface work in metal fabrication shops and field welding environments. Primary applications include weld bead leveling, light deburring, and surface prep ahead of painting or coating on mild steel. It also performs reliably on stainless steel fabrication work where controlled material removal and gouge resistance are priorities. The poly-cotton backing promotes even, progressive wear under medium unit pressure, keeping the disc tracking flat against the workpiece rather than loading or glazing prematurely.

Key Features

• 3M Precision-Shaped Grain delivers a fast, consistent cut rate from first use to disc end-of-life
• Individual flaps break down progressively, exposing fresh mineral throughout the disc life
• Poly-cotton backing supports controlled, even wear under medium unit pressure
• Less gouging than bonded wheels and fiber discs on flat and contoured surfaces
• Type 29 right-angle geometry suits both flat stock and curved weld profiles
• Effective on mild steel and stainless steel fabrication applications

Compatibility

Designed for use with standard 7-inch right-angle grinders. Suitable for medium-pressure grinding, weld leveling, light deburring, and surface preparation on mild steel and stainless steel.

Installation Notes

Flap discs of this size are installed and serviced by welders, fabricators, and metalworkers using standard right-angle grinders. Before mounting, confirm the grinder spindle speed rating meets or exceeds the disc maximum RPM rating printed on the hub. Always install the backing hub and locking nut fully before operating. Wear appropriate PPE — face shield, gloves, and hearing protection — when grinding.
