M.a. Ford. 43250027 Carbide Ball Bur SD-1-D 1/4 Inch Shank

Product Description

The M.A. FORD. 43250027 is a double-cut carbide abrasive bur in a ball head shape, conforming to industry specification SD-1-D. It is designed for material removal, deburring, shaping, and surface finishing tasks in metalworking and fabrication environments. The cutting head measures 0.25 inches in diameter with a length of cut of 0.2187 inches, mounted on a 1/4-inch shank. Overall length is 2.0 inches. The uncoated solid carbide head delivers the hardness and wear resistance needed for aggressive work on tough materials. Machinists, tool-and-die workers, and maintenance professionals use this bur with die grinders and rotary tools at speeds up to 45,000 RPM.

This bur is suited for use in industrial, production, and shop environments where precision material removal is required. It handles a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, as well as other hard materials. The double-cut tooth style generates a smoother finish and produces smaller chips compared to single-cut geometry, making it appropriate for both rough stock removal and finer finishing passes. Typical applications include port and cavity work, weld blending, mold and die finishing, and deburring of machined components.

Key Features

• Ball head shape per industry specification SD-1-D for contoured surface access
• Double-cut tooth geometry for efficient material removal and smoother finish
• Solid carbide head for high hardness and extended tool life on tough alloys
• Rated up to 45,000 RPM for use with standard die grinders and rotary tools
• 1/4-inch shank diameter fits common collet sizes on pneumatic and electric die grinders
• Compatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium

Compatibility

Designed as an OEM-style single-piece carbide bur for use in die grinders and rotary tools accepting a 1/4-inch shank collet. Suitable for material removal on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials as stated in the product specifications.

Installation Notes

Installation is performed by machinists and maintenance technicians using a die grinder or rotary tool with a matching 1/4-inch collet. Ensure the tool is fully powered down and the collet is secure before and after bur insertion. Do not exceed the rated maximum speed of 45,000 RPM. Always wear appropriate eye protection and follow shop safety protocols when operating rotary cutting tools on metal workpieces.
