Osg 800-8019 Carbide Ball Bur Double Cut 1/8 Inch Shank

Product Description

The OSG 800-8019 is a double-cut carbide abrasive bur with a ball head profile, designed for aggressive material removal in metalworking and fabrication applications. Conforming to SD-42 industry specification, this bur features an uncoated carbide head mounted on a 1/8-inch shank with an overall length of 1.5 inches. The double-cut tooth pattern produces a faster cut rate than single-cut geometry while generating less vibration and a smoother surface finish. Rated to 80,000 RPM, it is well-suited for use in pneumatic die grinders and rotary hand tools across a range of hard materials.

This bur is used in metal fabrication, tool and die work, weld blending, deburring, and surface preparation. Suitable for use on steel, stainless steel, cast iron, superalloys, and titanium, it handles hard and abrasion-resistant materials where standard HSS burs fall short. Common install scenarios include shop floor finishing, maintenance and repair work, and aerospace or heavy-equipment fabrication where close-tolerance material removal is required. Machinists, tool and die makers, and maintenance technicians are the primary users.

Key Features

• Ball head profile per SD-42 industry specification for contoured surface work and cavity blending
• Double-cut tooth style for fast stock removal with reduced chatter
• Carbide head construction handles steel, stainless steel, cast iron, superalloys, and titanium
• Rated to 80,000 RPM for use with high-speed pneumatic and electric die grinders
• Uncoated carbide head — no coating delamination concern in demanding applications
• Compact 1.5-inch overall length for access in confined areas

Compatibility

Designed as an OEM-style replacement or direct-use carbide bur for rotary die grinders and flex-shaft tools accepting a 1/8-inch shank, conforming to SD-42 industry specification.

Installation Notes

Installation is performed by machinists or fabricators using a standard die grinder collet rated for 1/8-inch shanks. Confirm the tool spindle is fully stopped and the power source is disconnected or air supply is isolated before changing burs. Do not exceed the rated 80,000 RPM maximum or operate the bur without appropriate eye protection and chip guarding. Secure the workpiece before use to prevent movement during high-speed material removal.
