Hertel SZ0015TW Abrasive Bur Tree Radius SF-3 Solid Carbide

Product Description

The HERTEL SZ0015TW is a solid carbide abrasive bur with a tree with radius end head shape, classified to industry specification SF-3. This rotary bur features a double cut tooth style that removes material efficiently on ferrous and non-ferrous metals, plastics, and composites. The cutting head measures 3/8 inch in diameter with a 3/4 inch length of cut, and it mounts on a standard 1/4 inch shank. The uncoated solid carbide construction delivers consistent hardness and wear resistance across a wide range of deburring, porting, and contouring tasks. Machinists, tool-and-die technicians, and fabricators reach for this bur when precision material removal in tight or contoured areas is required.

This bur is suited for use in die grinders, rotary tools, and flexible shaft machines in both production shop and maintenance environments. The SF-3 tree with radius profile is commonly applied to port and cavity work, weld blending, and radius blending on internal contours. Its 1/4 inch shank fits the collets and chucks most widely used in industrial and maintenance grinding setups. Both manual hand-tool operations and bench-mounted rotary tool applications are appropriate use cases for this bur geometry.

Key Features

• SF-3 tree with radius end geometry for contouring and cavity work
• Double cut tooth style for fast, smooth material removal
• Solid carbide head construction for hardness and long service life
• Uncoated head finish maintains sharp cutting edges without coating buildup
• 3/8 inch cutting diameter with 3/4 inch length of cut
• 1/4 inch shank fits standard die grinder and rotary tool collets

Compatibility

Designed as an OEM-style replacement or direct-use rotary bur for die grinders and rotary tools accepting a 1/4 inch shank collet, conforming to industry specification SF-3.

Installation Notes

Installation is performed by machinists or fabricators using standard collet-equipped die grinders or rotary tools. Ensure the tool is fully powered down and unplugged before inserting or removing the bur from the collet. Inspect the shank and cutting head for chips or cracks before each use, and do not exceed the rotational speed rating of the tool or bur. Eye protection and appropriate PPE should be worn at all times during operation per applicable shop safety standards.
