Hertel SZ20018T Abrasive Bur Tree Double Cut Solid Carbide

Product Description

The HERTEL SZ20018T is a solid carbide abrasive bur with a tree with pointed end head shape, designed for precision material removal in metalworking and fabrication applications. Built to industry specification SG-2, this double cut bur features a 5/16-inch cutting diameter and a 3/4-inch length of cut. The 1/4-inch shank diameter fits standard rotary tool chucks and die grinder collets. The uncoated solid carbide head delivers consistent cutting performance on ferrous and non-ferrous metals, as well as hardened alloys. Machinists, tool-and-die workers, and fabricators reach for this style of bur when profiling, deburring, or porting workpieces that require controlled stock removal in confined areas.

This bur is suited for use in machine shops, production facilities, and maintenance environments where precise contouring and deburring are required. The tree with pointed end geometry allows access to angled surfaces, cavities, and contoured profiles that flat or cylindrical burs cannot reach effectively. It is typically used in handheld die grinders or rotary tool setups for both bench work and in-place deburring on assembled components. The double cut tooth pattern produces a finer finish than single cut while still maintaining an efficient material removal rate across a range of workpiece materials.

Key Features

• Tree with pointed end head shape for accessing angled cavities and contoured surfaces
• Double cut tooth style balances material removal rate with surface finish quality
• Solid carbide construction provides hardness and wear resistance for extended tool life
• 5/16-inch cutting diameter with 3/4-inch length of cut
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• Uncoated head — no coating delamination risk during high-speed operation

Compatibility

Designed as an OEM-style replacement or direct-use abrasive bur for die grinders and rotary tools accepting a 1/4-inch shank, conforming to industry specification SG-2.

Installation Notes

Installation of this bur is performed by machinists and fabricators using standard die grinders or rotary tools with a compatible 1/4-inch collet. Before mounting, confirm the tool is powered off and disconnected from its air or electrical supply. Insert the shank fully into the collet and tighten to the tool manufacturer's specified collet torque before operation. Always wear appropriate eye protection and follow shop safety protocols when operating rotary cutting tools.
