Hertel SZ0011TW Abrasive Bur Tree Radius 1/2 in Solid Carbide

Product Description

The HERTEL SZ0011TW is a solid carbide abrasive bur designed for material removal, deburring, shaping, and surface finishing in metalworking and fabrication applications. It follows the SF-5 industry specification and features a tree with radius end head shape with a single cut tooth style. The cutting diameter measures 1/2 inch with a 1-inch length of cut, and the 1/4-inch shank diameter fits standard die grinders and rotary tools. The head is uncoated solid carbide, delivering hardness and wear resistance suited for ferrous and non-ferrous metals.

This bur is used in metal fabrication shops, tool and die operations, maintenance and repair environments, and precision machining applications. It is suited for porting, blending, and contouring work where a tree with radius end profile is required. The single cut configuration produces a smoother finish with less chatter and is preferred when working on aluminum, cast iron, and softer steel alloys. Machinists, tool grinders, and industrial maintenance technicians are the typical installers and operators.

Key Features

• SF-5 industry specification tree with radius end geometry for contouring and blending
• Solid carbide head construction for hardness and extended tool life
• Single cut tooth style reduces chatter and produces a smoother surface finish
• 1/2 inch cutting diameter with 1-inch length of cut for moderate material engagement
• 1/4 inch shank diameter fits most standard die grinders and rotary tool chucks
• Uncoated head — no coating buildup concerns when working aluminum or soft metals

Compatibility

Designed as an OEM-specification replacement and standard-stock abrasive bur for die grinders and rotary tools accepting a 1/4-inch shank, conforming to SF-5 industry geometry standards.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder or rotary tool with a compatible 1/4-inch collet or chuck. Secure the shank fully in the collet before operation and verify the tool RPM rating does not exceed the bur manufacturer rating for the cutting diameter. Wear appropriate eye protection and secure the workpiece before engaging the bur. Inspect the bur for chipping or wear before each use and remove from service if damage is present.
