Pferd 21823402 Carbide Bur Flame Double Cut 1/8 in

Product Description

The PFERD 21823402 is a double-cut carbide rotary bur with a flame head profile, designed for material removal, deburring, and shaping in metalworking and fabrication applications. The 1/8-inch cutting diameter and double-cut tooth pattern allow aggressive stock removal with reduced vibration compared to single-cut designs. The uncoated carbide head delivers consistent performance on ferrous and non-ferrous metals, hardened steels, and cast iron. With a maximum rated speed of 95,000 RPM, this bur is suited for use in high-speed die grinders and rotary tools. Machinists, tool-and-die workers, welders, and fabricators install and use this bur for precision profiling and finishing work in tight spaces.

This bur fits standard 1/8-inch collet die grinders and pencil grinders commonly used in production shops, maintenance environments, and field fabrication. The flame geometry is well-suited for contour work, blending weld seams, and accessing concave or irregular surfaces. The 1/4-inch length of cut and 1-1/2-inch overall length make it appropriate for detailed work where reach and control are priorities. It follows the SH-41 industry specification, making it a recognized standard form factor for interchangeability across tooling setups.

Key Features

• Flame head profile for contour deburring and weld blending on curved surfaces
• Double-cut tooth pattern for fast material removal with smoother finish than single-cut
• Solid carbide head, uncoated, rated for ferrous metals, non-ferrous metals, and cast iron
• 1/8-inch shank diameter fits standard die grinder collets
• Maximum speed rating of 95,000 RPM for high-speed rotary tool use
• SH-41 industry specification for standardized fitment and interchangeability

Compatibility

Designed for use in 1/8-inch collet die grinders, pencil grinders, and rotary tools rated for the 95,000 RPM maximum speed of this bur. Conforms to SH-41 industry specification.

Installation Notes

A licensed machinist or qualified fabricator should inspect the collet and spindle for wear before seating the bur. Always verify the tool RPM rating meets or exceeds 95,000 RPM before operation. Secure the shank fully in the collet and confirm the locking mechanism is tight before powering on. Eye protection and appropriate PPE are required per ANSI and shop safety standards when operating rotary burs.
