3M 7010300290 Flap Disc 7 Inch 40 Grit Cubitron Ii 967A

Product Description

The 3M 7010300290 is a 7-inch, 40-grit right-angle flap disc from the Cubitron II 967A line, engineered for medium-pressure grinding and surface preparation on flat and contoured workpieces. Built with 3M Precision-Shaped Grain, the disc delivers a fast, consistent cut rate throughout its service life. As individual flaps wear down, they expose fresh abrasive mineral, maintaining cutting performance without the need to increase pressure. Weighing 0.72 pounds, it is sized for standard 7-inch right-angle grinders used in fabrication and metalworking environments. Licensed tradespeople and fabricators in welding, sheet metal, and structural steel work are the primary installers and users of this product.

This flap disc is suited for medium-duty applications including weld leveling, light deburring, and surface prep prior to paint or coating on mild steel. It also performs well in stainless steel fabrication where finish quality and gouge resistance are priorities. The poly-cotton backing promotes controlled, even wear under medium unit pressure, making it a reliable choice for both flat surface work and contoured profiles where a rigid bonded wheel would lose contact.

Key Features

• 3M Precision-Shaped Grain construction for fast cut rate and extended disc life
• Individual flaps break down progressively, exposing fresh mineral throughout use
• Poly-cotton backing delivers controlled, even wear under medium unit pressure
• Less gouging than fiber discs and bonded abrasive wheels on mild and stainless steel
• Suitable for both flat and contoured surface grinding in a single disc
• Right-angle mounting fits standard 7-inch angle grinders

Compatibility

Designed for use on standard 7-inch right-angle grinders; suitable for mild steel and stainless steel applications including weld leveling, deburring, and pre-paint surface preparation.

Installation Notes

Mount this flap disc on a right-angle grinder rated for the disc diameter and maximum RPM before use. Disconnect or de-energize the grinder and confirm the spindle is fully stopped before changing discs. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination. Always follow ANSI B7.1 safety standards and wear appropriate PPE including eye and face protection when operating abrasive wheels.
