Sgs Pro 15878 SN-2 Inverted Cone Carbide Bur 3/8 in

Product Description

The SGS PRO 15878 is a double-cut tungsten carbide inverted cone bur conforming to the SN-2 industry specification. It is designed for aggressive material removal and deburring in metalworking applications. The bur features a 3/8-inch cutting diameter, a 3/8-inch length of cut, and an overall length of approximately 2.09 inches, with a 1/4-inch shank for use in standard die grinders and rotary tools. The double-cut tooth pattern generates less heat and produces a finer finish compared to single-cut burs. Licensed machinists, tool-and-die technicians, fabricators, and maintenance mechanics are the primary users of this tool.

This bur is suited for precision deburring, shaping, and stock removal on a wide range of metals including steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. It is commonly used in automotive, aerospace, and industrial maintenance shops where close-tolerance work in confined areas requires a compact, controlled cutting geometry. The inverted cone profile is particularly effective for undercutting, back-beveling, and cleaning up recessed features or counterbore edges.

Key Features

• SN-2 industry specification inverted cone geometry with a 13-degree included angle
• Double-cut tooth pattern for efficient chip removal and reduced chatter
• Tungsten carbide head - uncoated - for long service life on hard materials
• Rated to 37,500 RPM for use with standard pneumatic or electric die grinders
• 1/4-inch shank diameter fits the most common die grinder collet size
• Compatible with steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys

Compatibility

Designed as an OEM-specification replacement or direct-use carbide bur for die grinders and rotary tools accepting a 1/4-inch shank collet. Suitable for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys as specified by the manufacturer.

Installation Notes

Install and remove bur shanks only with the grinder fully de-energized and the air supply disconnected or power switch locked out. Seat the shank fully into the collet and tighten securely before operation. Do not exceed the rated 37,500 RPM maximum speed; verify the tool RPM rating before use. Eye protection and appropriate hand protection are required when operating rotary carbide burs.
