Sgs Pro 12578 Ball Carbide Bur SD-6 Double Cut 5/8 in

Product Description

The SGS PRO 12578 is a double-cut tungsten carbide abrasive bur in a ball head profile, designed for aggressive material removal and finishing on a wide range of metals and hard alloys. Conforming to industry specification SD-6, this bur features a 5/8 inch cutting diameter and a 1/4 inch shank, making it compatible with standard die grinders and rotary tools. The double-cut tooth pattern generates faster stock removal than single-cut styles and produces a smoother finish in one pass. Licensed machinists, fabricators, welders, and maintenance technicians rely on this type of bur for deburring, porting, contouring, and surface blending tasks.

This bur is suited for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. It performs well in both production and maintenance environments where precise material removal is needed on interior contours, weld beads, or drilled openings. The ball shape allows access to concave surfaces, rounded recesses, and spherical cavities that straight or tapered profiles cannot reach efficiently. Typical applications include metal fabrication shops, tool and die operations, aerospace maintenance, and heavy equipment repair.

Key Features

• SD-6 industry specification ball-profile bur for consistent dimensional standards
• Double-cut tooth style for faster stock removal and reduced chatter
• Tungsten carbide head provides hardness and wear resistance on ferrous and non-ferrous metals
• Uncoated head maintains cutting edge integrity without coating delamination risk
• Rated to 22,500 RPM for use with standard pneumatic and electric die grinders
• 1/4 inch shank fits the most common collet sizes on rotary and die grinder tools

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4 inch shank collet. Suitable for cutting and finishing steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys as stated by the manufacturer.

Installation Notes

Install this bur into a properly sized 1/4 inch collet and tighten securely before operation. Verify that the tool spindle speed does not exceed the 22,500 RPM maximum rating for this bur. Always wear appropriate eye protection and secure the workpiece before engaging the grinder. Do not exceed the rated RPM, apply side-loading beyond normal cutting pressure, or use a damaged or cracked bur.
