Pferd 21725212 Carbide Bur SM-2 Pointed Cone 1/4 in

Product Description

The PFERD 21725212 is a double-cut carbide abrasive bur designed for aggressive material removal and finish work on metals, castings, and hard materials. Built to the SM-2 industry specification, it features a pointed cone head geometry with a 1/4 inch cutting diameter and a 3/4 inch length of cut. The 1/4 inch shank fits standard die grinders and rotary tools. Rated to 48,000 RPM, this bur handles demanding applications without chattering. The uncoated carbide head delivers consistent cutting action across a range of workpiece materials. Machinists, tool-and-die workers, and fabricators are the primary users.

This bur is suited for deburring, contouring, and port work in confined areas where the pointed cone profile reaches tight geometry. The 14-degree included angle makes it effective for cleaning weld joints, chamfering internal bores, and detailing cast surfaces. It is commonly used in maintenance, repair, and production environments across metalworking, automotive, and general fabrication shops. The compact overall length of 1-15/16 inches keeps the tool manageable in close-quarters operations.

Key Features

• Double-cut tooth style for fast stock removal with reduced loading
• Pointed cone head shape accesses tight radii and confined cavities
• Carbide construction provides hardness and wear resistance on ferrous and non-ferrous materials
• 1/4 inch shank fits standard die grinder collets
• 48,000 RPM maximum rating supports high-speed rotary tool use
• SM-2 industry specification ensures consistent geometry and fit

Compatibility

Designed as an OEM-style replacement bur fitting any die grinder or rotary tool with a standard 1/4 inch collet and compatible with SM-2 specification tooling applications.

Installation Notes

Installation is performed by machinists, fabricators, or tool-and-die technicians using a standard die grinder with a 1/4 inch collet. Ensure the tool is fully de-energized and the collet nut is tightened securely before operation. Do not exceed the rated 48,000 RPM maximum speed. Inspect the shank for wear or damage before each use and replace if any deformation is present.
