Walter Surface Technologies 15F304 Mounted Flap Wheel 40 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15F304 is a mounted flap wheel designed for aggressive stock removal and surface blending on metal workpieces. Constructed with aluminum oxide abrasive on a cloth backing, it runs at up to 25,000 RPM on a 1/4-inch shank. At 2 inches in diameter and 1 inch in face width, this coarse-grade, 40-grit wheel delivers fast cutting action suited to deburring, weld blending, and edge finishing on aluminum, stainless steel, and carbon steel. It is installed directly into a die grinder or straight-shaft tool, making it a practical choice for fabrication shops and field service work on metal components.

This mounted flap wheel is used in light fabrication, maintenance, and repair applications where controlled surface conditioning is required. Its cloth-backed aluminum oxide construction handles heat and flex better than rigid abrasive points, making it well suited for contoured surfaces and inside radii. Typical applications include weld seam blending, deburring machined parts, and surface prep before coating or inspection. It is compatible with bench grinders and straight-shaft tools accepting a 1/4-inch shank.

Key Features

• Aluminum oxide abrasive on cloth backing for durability and flexibility
• 40 grit, coarse grade for aggressive material removal
• 25,000 maximum RPM rating for use with high-speed die grinders
• 1/4-inch shank mount for compatibility with standard straight-shaft tools and bench grinders
• 2-inch diameter and 1-inch face width suited to detail work and inside contours
• Rated for use on aluminum, stainless steel, and carbon steel

Compatibility

Designed for use with bench grinders and straight-shaft tools equipped with a 1/4-inch collet or chuck. Rated for material applications on aluminum, stainless steel, and steel.

Installation Notes

Installation is performed by threading the 1/4-inch shank into the collet of a die grinder or straight-shaft tool and tightening securely before operation. Always verify that the tool spindle speed does not exceed the 25,000 RPM maximum rating of the wheel. Disconnect power to the tool before mounting or removing the flap wheel. Wear appropriate eye protection and observe all applicable ANSI B11 and OSHA grinding safety requirements during use.
