M.a. Ford. 42375027 Carbide Bur SC-3-D Ball Nose Cylinder

Product Description

The M.A. FORD. 42375027 is a double-cut carbide abrasive bur with a ball nose cylinder (cylinder with radius) head profile, conforming to industry specification SC-3-D. It features a 3/8-inch cutting diameter, a 3/4-inch length of cut, and a 1/4-inch shank for use in standard die grinders and rotary tools. The carbide head delivers aggressive material removal across a wide range of workpiece materials, making this bur a practical choice for deburring, blending, porting, and surface finishing tasks. It is uncoated and rated for use up to 30,000 RPM. Machinists, tool and die technicians, and fabricators are the primary installers and users of this tool.

This bur is suited for both shop and field applications where controlled material removal is required on ferrous and non-ferrous stock. Typical use cases include deburring weld seams, shaping castings, cleaning up ports, and finishing hard-to-reach contours. The double-cut tooth geometry produces a smoother finish than single-cut styles while still removing material efficiently. It is appropriate for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials.

Key Features

• SC-3-D industry specification, ball nose cylinder head shape for radius blending and contouring
• Double-cut tooth style for efficient material removal and smoother surface finish
• Carbide head construction handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• 30,000 RPM maximum speed rating for compatibility with high-speed die grinders
• 3/8-inch cutting diameter with 3/4-inch length of cut
• 1/4-inch shank fits standard collet-type die grinders and rotary tools

Compatibility

Designed as an OEM-style carbide bur for use in any die grinder or rotary tool accepting a 1/4-inch shank collet, for material removal on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium.

Installation Notes

Install and remove this bur only after the die grinder or rotary tool has been fully powered down and the collet has released all stored energy. Secure the shank fully within the collet to the manufacturer-specified depth before operation. Always wear appropriate eye and face protection when operating carbide burs at high RPM. Inspect the bur head for chips or cracks before each use and do not operate above the 30,000 RPM rating.
