Sgs Pro 14953 SK-3 Cone Carbide Bur Double Cut 3/8 in

Product Description

The SGS PRO 14953 is a tungsten carbide abrasive bur in the SK-3 cone geometry, designed for aggressive material removal and deburring in metalworking and fabrication applications. The double-cut tooth pattern produces faster stock removal than single-cut fluting and leaves a moderately smooth finish suitable for most metal prep work. The cone head measures 3/8 inch in cutting diameter with a 90-degree included angle, an overall length of 2.0625 inches, and a 1/4 inch shank for use in standard die grinders and rotary tools. Maximum rated speed is 37,500 RPM. This bur is sold individually and is uncoated.

This bur is suited for use in metal fabrication shops, maintenance facilities, and manufacturing environments where machinists, pipefitters, welders, and tool-and-die technicians need to deburr, shape, or enlarge holes in hard metals. Its double-cut geometry makes it effective on ferrous and non-ferrous materials including steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. The 1/4 inch shank fits the collets of most standard pneumatic and electric die grinders found in trade and shop environments.

Key Features

• SK-3 cone geometry with 90-degree included angle for precise material removal in tapered and conical surfaces
• Double-cut fluting delivers fast stock removal with moderate surface finish
• Tungsten carbide head withstands heat and wear across a wide range of hard metals
• Rated to 37,500 RPM for use with high-speed die grinders
• Uncoated head on a 1/4 inch shank - fits most standard die grinder collets
• Compatible material list includes steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys

Compatibility

Designed for use with standard die grinders and rotary tools accepting a 1/4 inch shank collet. Rated for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys per manufacturer specification.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a die grinder fitted with a matching 1/4 inch collet. Always power down and disconnect the tool before inserting or removing the bur. Verify that the tool RPM rating meets or exceeds the bur maximum of 37,500 RPM before operation, and confirm the collet is fully tightened to prevent slippage. Eye protection and appropriate PPE are required when operating rotary cutting tools on metal.
