Htc H-33 Abrasive Bur Tree Radius 1/4in Single Cut Hss

Product Description

The HTC H-33 is a tree-with-radius-end abrasive bur designed for material removal, deburring, shaping, and surface finishing in metalworking and fabrication applications. Built from high speed steel with an uncoated finish, it delivers consistent single-cut performance on ferrous and non-ferrous metals. The bur features a 0.25 inch cutting diameter, a 0.5 inch length of cut, and a 1.5 inch overall length. The 0.125 inch shank fits standard die grinders and rotary tool chucks commonly found in machine shops, maintenance facilities, and fabrication environments. Licensed tradespeople and skilled machinists rely on this geometry for reaching contoured or recessed areas.

The H-33 is suited for precision deburring, port matching, weld cleanup, and contour grinding where a tree-with-radius profile is required. The single-cut tooth style produces a smoother finish and longer chip flow compared to double-cut designs, making it appropriate for finish passes on steel, cast iron, and similar hard materials. It is a standard bench-stock item for tool cribs and die shops handling light to medium stock removal tasks.

Installation Notes

Installation is performed by machinists, tool and die makers, and maintenance technicians using standard die grinders or rotary tools.

Secure the shank fully within the collet and tighten to the tool manufacturer's specified torque before operation. Always wear appropriate eye protection and follow applicable shop safety standards when operating rotary abrasive tooling.
