Hertel SZ0028B Abrasive Bur Ball 5/16 in Double Cut Carbide

Product Description

The HERTEL SZ0028B is a solid carbide abrasive bur with a ball-shaped head, designed for material removal, deburring, and surface finishing in metal fabrication and maintenance applications. Built to industry specification SD-2, it features a double cut tooth style that produces faster stock removal with a smoother finish compared to single cut configurations. The 5/16 inch cutting head diameter and 1/4 inch shank diameter make it compatible with standard die grinders and rotary tools used across mechanical, welding, and industrial maintenance trades. The uncoated solid carbide construction delivers hardness and heat resistance suited for ferrous and non-ferrous metals.

This bur is used in applications requiring precision material removal in confined areas, weld blending, port matching, and deburring of drilled or cast openings. The ball head geometry allows access to curved surfaces, internal radii, and contoured workpieces. It is a practical choice for machinists, fabricators, maintenance technicians, and toolmakers working on production floors or in field repair environments where consistent cut performance is required.

Key Features

• Ball head shape for access to curved surfaces and internal contours
• Double cut tooth style for fast stock removal and reduced chatter
• Solid carbide construction for hardness and extended tool life
• Uncoated head for broad material compatibility
• 5/16 inch cutting diameter per SD-2 industry specification
• 1/4 inch shank diameter fits standard die grinders and rotary tools

Compatibility

Designed as an SD-2 specification ball bur for use with die grinders and rotary tool handpieces accepting a 1/4 inch shank.

Installation Notes

Secure the shank fully into the collet of the die grinder or rotary tool before operation and verify the collet is properly tightened. Inspect the bur for cracks or chipping before each use and do not operate above the tool manufacturer's rated RPM for the shank diameter. Wear appropriate eye protection and secure the workpiece to prevent movement during grinding. Disconnect or de-energize the tool before changing burs.
