M.a. Ford. 46250020 Carbide Abrasive Bur Tree 0.25in

Product Description

The M.A. FORD. 46250020 is a single-cut carbide abrasive bur with a tree-with-pointed-end head geometry, designed for precision material removal in demanding industrial and trade applications. Built to the SG-1 industry specification, this bur features a 0.25 inch cutting diameter and a 0.625 inch length of cut. The uncoated carbide head delivers consistent cutting performance across a wide range of hard and abrasive materials. With a maximum rated speed of 45,000 RPM, it is suited for use with high-speed rotary tools and die grinders. Machinists, tool-and-die technicians, and fabricators are the primary installers and users of this type of bur.

This bur is appropriate for stock removal, deburring, shaping, and contouring operations on a variety of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The tree-with-pointed-end profile allows access to contoured surfaces, cavity work, and angled areas where flat or cylindrical profiles cannot reach. It is commonly used in fabrication shops, maintenance and repair environments, and precision machining operations requiring controlled material removal.

Compatibility

Designed as an OEM-style replacement or standard-supply carbide abrasive bur for use with rotary tools and die grinders accepting a 0.25 inch shank. Suitable for work on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials as stated in the product specification.

Installation Notes

Installation of carbide burs should be performed by a qualified machinist or technician familiar with rotary tool operation and applicable shop safety standards. Always power down and disconnect the rotary tool or die grinder before inserting or removing the bur from the collet. Confirm the tool spindle speed does not exceed the 45,000 RPM maximum rating for this bur. Use appropriate eye protection and secure workpieces properly before beginning any cutting or deburring operation.
