M.a. Ford. 44250030L6 Carbide Abrasive Bur Oval 1/4in

Product Description

The M.A. FORD. 44250030L6 is a carbide abrasive bur with an oval head profile and a fine tooth style, designed for precision material removal and surface finishing in industrial and trade applications. The bur features a 1/4 inch shank diameter and an overall length of 6.375 inches, with a cutting diameter of 0.25 inches and a length of cut of 0.375 inches. The uncoated carbide head delivers consistent cutting performance across a wide range of workpiece materials. Machinists, fabricators, and tool-and-die tradespeople rely on this style of bur for deburring, blending, and contouring in tight or hard-to-reach areas.

This bur is suited for use in die grinders and rotary tools operating up to 45000 RPM. It performs across a broad range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, as well as other hard materials. The oval head shape makes it well-suited for internal contours, ports, and curved cavity work. It is commonly used in metalworking shops, maintenance and repair operations, and precision fabrication environments where fine material removal and surface quality are required.

Key Features

• Oval head profile for contouring internal curves and cavities
• Fine tooth style for smooth surface finishes and controlled material removal
• Carbide head construction for durability on hard and abrasive workpiece materials
• 1/4 inch shank fits standard die grinder and rotary tool collets
• Rated to 45000 RPM for compatibility with high-speed rotary tools
• Effective on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium

Compatibility

Designed to fit standard 1/4 inch collet die grinders and rotary tools. Industry specification SE-1L6-F applies to this bur geometry and tooth configuration.

Installation Notes

Installation and operation of abrasive burs should be performed by qualified machinists or metalworking tradespeople familiar with rotary tool safety. Before mounting the bur, ensure the rotary tool or die grinder is fully powered down and unplugged. Verify that the tool spindle speed does not exceed the 45000 RPM rating of this bur. Always secure the shank fully in the collet and inspect the bur for any visible damage before use. Appropriate eye protection and hearing protection are required during operation.
