Hertel SZ2022TB Abrasive Bur Tree Radius End 3/8 in

Product Description

The HERTEL SZ2022TB is a solid carbide abrasive bur with a tree-with-radius-end head geometry and a single-cut tooth style. It is designed for material removal, deburring, and shaping operations on metals, composites, and hard materials in fabrication, toolroom, and maintenance environments. The cutting diameter measures 3/8 inches, the length of cut is 3/4 inches, and the overall length is 6 inches. The 1/4-inch shank fits standard die grinders and rotary tool chucks. The uncoated solid carbide construction delivers consistent cutting performance across a range of workpiece materials.

This bur is suited for die grinders, flexible shaft machines, and CNC tool changers equipped with a 1/4-inch collet. Typical applications include weld cleanup, port matching, mold and die work, and contour finishing where a tree-with-radius-end profile is required to reach recessed or curved surfaces. It is used by machinists, tool-and-die makers, maintenance mechanics, and metalworking fabricators. The SF-3L6 industry specification identifies this bur within the standardized carbide bur classification system.

Key Features

• Tree with radius end head shape for contoured and recessed material removal
• Single-cut tooth style for smooth finishes and controlled stock removal
• Solid carbide head construction for durability in hard materials
• Uncoated head — no coating buildup to affect dimensional clearance
• 3/8-inch cutting diameter with 3/4-inch length of cut
• 1/4-inch shank diameter fits standard die grinder collets

Compatibility

Designed to fit die grinders, flexible shaft machines, and rotary tools with a 1/4-inch collet. Conforms to industry specification SF-3L6 for standardized carbide bur interchangeability.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a standard die grinder with a matching 1/4-inch collet. Ensure the tool is fully de-energized and the collet is clean and undamaged before seating the shank. Do not exceed the RPM rating of the host tool. Eye protection and appropriate PPE are required when operating rotary carbide burs.
