Sgs Pro 13878 Abrasive Bur Tree Double Cut 5/16 in

Product Description

The SGS PRO 13878 is a double-cut tungsten carbide abrasive bur with a tree-with-pointed-end head geometry, designed for aggressive material removal in metalworking and fabrication applications. The 5/16-inch cutting diameter and 3/4-inch length of cut give the tool reach and surface coverage suited to contouring, deburring, and port work. With a 1/4-inch shank and a maximum rated speed of 45,000 RPM, it is compatible with standard die grinders and rotary tools used in production and maintenance environments. The uncoated tungsten carbide head holds an edge across a broad range of hard materials without requiring a specialty driver or adapter.

This bur is suited for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. Typical applications include weld blending, cavity shaping, flash removal, and precision deburring in fabrication shops, maintenance facilities, and tooling operations. The tree-with-pointed-end profile is well suited for reaching into recessed areas and contoured surfaces where flat or cylindrical profiles cannot make full contact. It is installed and used by machinists, pipefitters, welders, and maintenance technicians.

Key Features

• Double-cut flute pattern for faster stock removal and a smoother finish pass
• Tree with pointed end head shape for access to recessed and contoured workpiece geometry
• Tungsten carbide construction for extended tool life on ferrous and non-ferrous metals
• Rated to 45,000 RPM for use with standard pneumatic and electric die grinders
• 1/4-inch shank fits the most common die grinder collet size
• SG-2 industry specification for consistent cross-supplier sizing and performance standards

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch collet. Rated for cutting steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys.

Installation Notes

Install the bur into a 1/4-inch collet and tighten securely before operation. Verify that the tool, grinder, and workpiece are secure before reaching rated speed. Always wear eye protection and appropriate PPE when operating rotary abrasive tools. Do not exceed the 45,000 RPM maximum rated speed for this bur.
