Company record

Circofile manufactures a comprehensive portfolio of carbide burs, covering every type from standard industrial models to custom‑designed tools for niche applications. The product line includes miniature carbide burs with 1/4‑inch and 3/4‑inch diameter shanks, as well as a wide array of cutting geometries such as standard, double, diamond, fine, extra‑fine, coarse, rough and fast‑mill profiles. Specialized cuts—HSR, herringbone and high‑helix—are also offered. In addition to individual burs, Circofile stocks bur‑routers, internal grinding burs and art‑foundry burs, and provides special shank options, including extra‑long and metric sizes, on most models. Customers can purchase single pieces or assorted bur sets. The tools are engineered for material removal across a spectrum from soft to hard substances, including aluminum, bronze, cast iron, fiberglass and stone. Primary markets served encompass art foundries producing statues and sculptures, automotive shops performing cylinder‑head porting, aircraft manufacturers machining turbine blades, and welding operations addressing excess weld flash. Circofile further supports clients with a bur‑resharpening and life‑extension service, and offers expert guidance on tool selection and proper usage.
