Sgs Pro 19211 Cylinder Ball End Abrasive Bur 3/8 in

Product Description

The SGS PRO 19211 is a double-cut tungsten carbide abrasive bur with a cylinder ball end head geometry, designed for material removal, shaping, and deburring in metal fabrication, tool and die work, and general industrial applications. The cutting head measures 0.375 inches in diameter with a 0.75-inch length of cut, mounted on a 0.25-inch shank. Rated to 37,500 RPM, this bur delivers aggressive stock removal on ferrous and non-ferrous metals, aluminum, and hard plastics. The uncoated tungsten carbide head provides the hardness needed for repeated use in demanding shop environments. Machinists, tool grinders, and fabricators typically reach for this style of bur for contour work and cavity finishing.

This cylinder ball end bur is suited for die grinding in production and maintenance settings. The ball end profile allows access to concave surfaces, slots, and blind cavities where flat-end or tapered burs cannot follow the geometry. The 2.5-inch overall length gives adequate reach for most rotary tool and air die grinder chucks. It is appropriate for use on ferrous metals, cast iron, steel alloys, and hard plastics in both shop and field service scenarios. Industry specification cross-reference is SE-51G D/C.

Key Features

• Double-cut flute pattern for fast material removal and reduced chatter on metal surfaces
• Cylinder ball end geometry for contouring, blending, and cavity work
• Tungsten carbide head for long service life on hard materials
• Maximum rated speed of 37,500 RPM compatible with most air die grinders and rotary tools
• 0.25-inch shank fits standard die grinder and rotary tool collets
• Uncoated head maintains consistent cutting geometry without coating buildup

Compatibility

Designed for use with die grinders and rotary tools accepting a 0.25-inch shank collet. Industry specification SE-51G D/C applies to this bur geometry and cut style.

Installation Notes

Carbide burs are installed and removed by a licensed machinist or trained fabricator using the appropriate collet wrench for the grinder in use. Always confirm the grinder RPM rating meets or exceeds the bur maximum of 37,500 RPM before operation. Secure the workpiece firmly before grinding to prevent movement. Wear appropriate eye protection and gloves in accordance with applicable shop safety standards.
