Sgs Pro 15550 Carbide Burr Cone SM-3 0.25in Single Cut

Product Description

The SGS PRO 15550 is a single-cut tungsten carbide burr in the SM-3 cone profile, designed for metal removal, deburring, and shaping work in industrial and trade applications. The cone geometry with a 10-degree included angle suits chamfering, countersinking, and contour work in confined areas. With a 0.25-inch cutting diameter, a 1-inch length of cut, and a 2-inch overall length, this burr fits standard 0.25-inch collet die grinders and rotary tools. It is rated to 55,000 RPM and is supplied uncoated and ready to use. Machinists, fabricators, weld-prep technicians, and pipefitters are the primary users.

This burr is suited for stock removal and finishing on steel, hardened steel, stainless steel, cast iron, titanium, cermet, nickel, copper, and copper alloys. The SM-3 cone profile is commonly used in weld preparation, port matching, deburring drilled holes, and surface blending on both flat and curved workpieces. It is applicable in fabrication shops, maintenance facilities, and field service environments where a die grinder or flex-shaft rotary tool is the primary driver.

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.25-inch collet. Compatible with steel, hardened steel, stainless steel, cast iron, titanium, cermet, nickel, copper, and copper alloys per the SM-3 industry specification.

Installation Notes

Install the burr into a die grinder or rotary tool with a matching 0.25-inch collet and tighten securely before use. Verify the tool is rated to handle the burr RPM rating before operating. Always wear eye protection and appropriate PPE when operating rotary cutting tools. Inspect the burr for chips or cracks before each use and remove from service if damage is found.
