M.a. Ford 42250030 SC-1 Carbide Abrasive Bur 1/4 Inch

Product Description

The M.A. FORD 42250030 is a carbide abrasive bur in the SC-1 cylinder with radius (ball nose cylinder) configuration, designed for aggressive material removal and surface finishing in metalworking and fabrication applications. With a 1/4-inch cutting diameter and a 1/4-inch shank, this bur fits standard die grinders and rotary tools used daily in shop and field environments. The fine tooth style produces a smoother finish with reduced chatter on hard and abrasive materials. Rated to 45,000 RPM, it delivers consistent cutting performance across a broad range of metals. Installation and use require no special tooling beyond a compatible collet-style grinder.

This bur is suited for deburring, contouring, chamfering, and weld preparation on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The ball nose cylinder profile makes it especially effective for internal radius blending, port work, and cavity finishing where a flat-end bur cannot reach cleanly. Fabricators, tool-and-die machinists, and maintenance technicians routinely reach for this profile when working in confined areas or blending complex curved surfaces.

Key Features

• SC-1 ball nose cylinder profile for internal radius blending and contour finishing
• Solid carbide head construction for hardness and wear resistance on tough materials
• Fine tooth style for smoother surface finish and reduced vibration
• 45,000 RPM maximum speed rating for use with high-speed die grinders
• 1/4-inch shank fits standard collet die grinders and rotary tool chucks
• Uncoated head — no coating delamination risk on abrasive or interruptive cuts

Compatibility

Designed for use in standard 1/4-inch collet die grinders and rotary tools. Suitable for cutting and finishing operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium per the manufacturer material application specification.

Installation Notes

Installation is performed by a machinist, fabricator, or maintenance technician using a compatible die grinder with a 1/4-inch collet. Ensure the grinder is powered off and the collet is fully tightened before operation. Do not exceed the 45,000 RPM maximum speed rating. Wear appropriate eye and face protection per applicable shop safety standards whenever operating rotary cutting tools.
