Sgs Pro 13503 SF-11 Tree Radius Carbide Bur Double Cut

Product Description

The SGS PRO 13503 is a tungsten carbide abrasive bur in the SF-11 ball nose tree with radius profile, designed for aggressive material removal in die grinding, deburring, and surface preparation applications. The double cut tooth pattern produces fast stock removal with a smoother finish compared to single cut geometry. With a 1/8 inch cutting diameter and 2.25 inch overall length, this bur fits standard die grinder and rotary tool collets via its 1/4 inch shank. Maximum rated speed is 100,000 RPM. Installation and use require no special tooling beyond a compatible rotary tool with a 1/4 inch collet.

This bur is suited for metalworking professionals working across a broad range of ferrous and non-ferrous materials. The SF-11 profile is commonly used for contoured surface work, port matching, weld cleanup, and cavity blending in tool-and-die, maintenance, and fabrication settings. The uncoated tungsten carbide head performs across a wide material range including steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys.

Installation Notes

Installation is performed by machining and metalworking tradespeople using standard die grinders or flexible-shaft rotary tools. Always power down and unplug the rotary tool before inserting or removing the bur from the collet. Secure the shank fully within the collet and tighten per tool manufacturer guidelines before operating. Do not exceed the rated maximum RPM, and always wear appropriate eye protection and gloves when operating carbide burs.
