3M 7000148199 Cubitron Ii 967A Flap Disc 5 in 60 Grit

Product Description

The 3M 7000148199 is a Type 29 right-angle flap disc built on the Cubitron II 967A platform, engineered for medium-pressure grinding and surface preparation on flat and contoured workpieces. At 5 inches in diameter and 60 grit, it is suited for weld leveling, light deburring, and surface prep ahead of paint or coating. The disc is powered by 3M Precision-Shaped Grain, a ceramic abrasive geometry that fractures along controlled planes to expose fresh cutting edges throughout the life of the disc. Individual flaps break down progressively, maintaining a consistent cut rate from first use to last. Weighing 0.22 pounds, it is light enough for extended overhead or vertical work without operator fatigue.

This flap disc is primarily used in metal fabrication shops, structural steel work, and maintenance welding environments. It performs on mild steel for weld removal and scale cleanup, and on stainless steel where finish quality and gouge resistance matter. The poly-cotton backing provides controlled, even wear under medium unit pressure, making it appropriate for both flat passes and work on contoured geometry. Fabricators, ironworkers, and maintenance welders typically reach for this disc when fiber discs leave too much surface damage or bonded wheels remove too aggressively.

Key Features

• 3M Precision-Shaped Grain delivers fast, consistent cut and longer disc life versus conventional ceramic abrasives
• Progressive flap breakdown continuously exposes fresh mineral, maintaining cut rate through the full disc life
• Poly-cotton backing supports controlled, even wear under medium unit pressure on flat and contoured surfaces
• Reduced gouging compared to fiber discs and bonded wheels, minimizing rework before paint or coating
• Right-angle Type 29 configuration suits both flat grinding and moderate contour work
• 5 inch diameter and 60 grit target weld leveling, light deburring, and pre-paint surface preparation

Compatibility

Designed for use on standard 5 inch right-angle grinders with a compatible arbor. Suitable for mild steel and stainless steel applications requiring medium-pressure surface preparation or weld leveling.

Installation Notes

Mounting and use should be performed by personnel familiar with abrasive wheel safety per ANSI B7.1 guidelines. Verify the grinder spindle speed rating meets or exceeds the maximum RPM marked on the disc before mounting. Always power down and disconnect the grinder before changing discs, and inspect the disc for cracks or damage prior to each use. Appropriate eye protection, face shield, and hearing protection are required during operation.
