Hertel SZ20017T Abrasive Bur Tree 1/4 in Shank Solid Carbide

Product Description

The HERTEL SZ20017T is a solid carbide abrasive bur with a tree-with-pointed-end head shape, designed for aggressive material removal in tight and contoured work areas. It features a double cut tooth style that shears material in both directions, improving stock removal rate and leaving a smoother finish than single cut alternatives. The 1/4 inch shank fits standard die grinder collets and rotary tool chucks used across metalworking, fabrication, and maintenance trades. The uncoated solid carbide head delivers hardness and heat resistance suited for ferrous and non-ferrous metals, hardened steel, and cast iron.

This bur is used in applications requiring precise deburring, porting, shaping, and surface blending on metal workpieces. It is well suited for fabrication shops, tool and die work, aerospace component finishing, and general maintenance machining. The pointed tree profile allows access into angled recesses, cavities, and port entries where flat or cylindrical profiles cannot reach. Machinists, tool grinders, and skilled fabricators are the primary users in both job shop and production environments.

Key Features

• Tree with pointed end head shape for access into angled cavities and recessed areas
• Double cut tooth style for faster stock removal and smoother finish
• Solid carbide head construction for hardness and extended tool life
• 1/4 inch shank diameter compatible with standard die grinder collets
• 5/8 inch length of cut provides adequate working depth for most burring tasks
• Uncoated head suitable for use on ferrous metals, non-ferrous metals, and hardened alloys

Compatibility

Designed as an OEM-style replacement bur conforming to industry specification SG-1, compatible with 1/4 inch collet die grinders and rotary tools accepting standard shank carbide burs.

Installation Notes

Installation is performed by machinists and fabricators using die grinders or rotary tools with a 1/4 inch collet. Always power down and disconnect the tool from its air supply or electrical source before inserting or removing the bur. Ensure the shank is fully seated and the collet nut is properly tightened before operating. Do not exceed the recommended RPM rating of the tool for the bur diameter in use.
