M.a. Ford. 43250020 Carbide Ball Abrasive Bur SD-1

Product Description

The M.A. FORD. 43250020 is a single-cut carbide abrasive bur with a ball head profile, designed for precision material removal, deburring, and surface finishing in metalworking applications. The cutting head measures 0.25 inches in diameter with a length of cut of 0.2187 inches and an overall length of 2.0 inches. The 0.25-inch shank is compatible with standard die grinder chucks and rotary tool collets. Rated to 45,000 RPM, this bur delivers controlled stock removal across a wide range of materials. The uncoated carbide head provides consistent cutting geometry without coating buildup that can affect surface finish.

This bur suits applications in metal fabrication shops, maintenance facilities, and manufacturing environments where close-tolerance work is required. Typical tasks include weld blending, port matching, cavity shaping, and deburring drilled or cast features. The ball profile makes it well suited for contoured surfaces, internal radii, and hard-to-reach cavities. It is installed and operated by machinists, tool-and-die makers, and maintenance technicians working with die grinders or high-speed rotary tools.

Key Features

• Ball head geometry for contouring, radius work, and internal cavity finishing
• Single-cut tooth style for smooth material removal with reduced chatter
• Uncoated carbide head maintains sharp cutting edges across a wide material range
• Rated to 45,000 RPM for use with standard high-speed die grinders
• Industry specification SD-1 designation for consistent sizing and fitment

Compatibility

Designed for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Fits any die grinder or rotary tool accepting a 0.25-inch shank collet.

Installation Notes

Install into a properly sized collet and tighten securely before use. Always confirm the tool spindle RPM rating meets or exceeds the bur rating before operating. Wear appropriate eye protection and secure the workpiece. Do not exceed the 45,000 RPM maximum rating, and inspect the bur for chips or damage before each use.
