Hertel SZ0018B Abrasive Bur Ball 5/16 in Solid Carbide

Product Description

The HERTEL SZ0018B is a solid carbide abrasive bur with a ball head geometry, designed for material removal, deburring, and surface finishing in metal fabrication and maintenance applications. The ball-shaped cutting head measures 5/16 inches in cutting diameter and is mounted on a 1/4-inch shank for use with standard die grinders and rotary tools. The single-cut tooth style delivers efficient stock removal with good surface finish control. At 0.031 pounds, this is a compact, lightweight tool suited for precision hand-held grinding work in tight spaces. The uncoated solid carbide construction provides hardness and wear resistance across a range of workpiece materials.

This bur is suited for use in metalworking, tool and die, maintenance and repair, and light fabrication environments. Typical applications include deburring drilled or cast holes, blending weld beads, porting and relieving metal components, and surface contouring in hard-to-reach areas. The ball profile is particularly useful for concave surface work and internal radius blending. Machinists, tool grinders, maintenance mechanics, and fabricators working with ferrous and non-ferrous metals are the primary installers and users of this type of bur.

Key Features

• Ball head geometry suits concave surface blending and internal radius work
• 5/16-inch cutting diameter for moderate material removal in confined areas
• Solid carbide construction for hardness and extended wear life
• Single-cut tooth style balances stock removal rate with surface finish quality
• 1/4-inch shank diameter fits standard die grinder collets and rotary tool chucks
• Uncoated head allows use across a broad range of metal workpiece materials

Compatibility

Designed for use with standard 1/4-inch collet die grinders and rotary tools. Meets SD-2 industry specification for ball-style carbide burs with a 5/16-inch cutting diameter and 1/4-inch shank.

Installation Notes

Install and remove burs only with the die grinder or rotary tool fully powered off and air supply disconnected or battery removed. Secure the shank fully into the collet and tighten to the tool manufacturer specification before operation. Always wear appropriate eye protection and gloves when operating rotary cutting tools. Do not exceed the RPM rating of the tool or apply excessive side-load pressure to the bur shank.
