Hertel SZ20011T Abrasive Bur Tree Double Cut Solid Carbide

Product Description

The HERTEL SZ20011T is a solid carbide abrasive bur with a tree with pointed end head shape, designed for material removal, deburring, and surface finishing in metalworking and fabrication applications. Built to industry specification SG-53, this bur features a double cut tooth style that delivers efficient chip removal and smooth surface results. The 3/16 inch cutting diameter and 1/2 inch length of cut make it well suited for working in confined areas and contoured surfaces. It mounts on a standard 1/8 inch shank and is supplied uncoated. Machinists, tool and die makers, and fabricators use this type of bur with die grinders and rotary tools.

This bur is appropriate for use in precision material removal tasks across a range of base metals and harder alloys. The tree with pointed end geometry allows access to tapered grooves, angled cavities, and transition radii that straight or ball-nose profiles cannot reach. It is a single-piece solid carbide construction with no brazed inserts, which maintains concentricity and reduces deflection at higher RPM. Typical applications include weld cleanup, port matching, mold work, and general deburring in job shop and production environments.

Key Features

• Solid carbide head construction for rigidity and extended tool life in harder materials
• Double cut tooth style for faster material removal with reduced chatter
• Tree with pointed end geometry for access to tapered and angled features
• 3/16 inch cutting diameter with 1/2 inch length of cut
• Standard 1/8 inch shank fits common die grinders and rotary tool chucks
• Uncoated head, no coating delamination risk in abrasive or interrupted cuts

Compatibility

Designed as an OEM-style replacement bur conforming to industry specification SG-53, compatible with die grinders and rotary tools accepting a 1/8 inch shank collet.

Installation Notes

Installation is performed by machinists or fabricators using a die grinder or rotary tool with a matching 1/8 inch collet. Before mounting, confirm the tool is fully powered off and unplugged or air supply is disconnected. Seat the shank fully into the collet and tighten the collet nut to the tool manufacturer specification before operation. Always wear appropriate eye protection and observe the maximum RPM rating of the rotary tool when running carbide burs.
