Carbide Burrs

Carbide burrs are machined tools that are used to clean casting areas that are internal or hard to reach. Our carbide burrs feature precision ground flutes. These flutes are manufactured on a five-axis CNC fluting machine resulting in precise control of tool geometry. This eliminates chatter and premature wear. Our carbide burr heads are made exclusively with American manufactured carburized tungsten with cobalt binders sintered at high temperatures. Their precise cutting and rapid stock removal reduce the amount of time to complete the application providing additional cost savings. Carbide burrs are used by mounting to air or electric tools. They are excellent for cleaning hard-to-reach and internal cavities on castings. They have a long life but can dull over time. Dull burrs can be returned for resharpening to extend the tool’s life.

We also offer long shank burrs, miniature burrs, and aluminum cut burrs. Our miniature burrs are used on a wide range of pneumatic, electric and flexible drive tools. Miniature burrs allow for effective freehand stock removal, weld preparation, and removal without contamination. Our aluminum cut burrs are manufactured in the United States from a high-quality carbide. The precise milling cutter-style flutes assure fast chip flow and swift stock removal. These aluminum cut burrs are machine ground to exact tolerances. The engineering of these tools offers a smooth, quality surface finish.

About Us

Carpenter Brothers, Inc. is the leading supplier of equipment, consumables, and technical expertise for the metal casting industry. Founded in 1917, by Everett and Milton Carpenter, the brothers were able to use their unique foundry experiences to solve the problem of the day: a reliable sand source.  They got their foot in the door by selling natural bonded molding sand, which was mined by hand, loaded into horse-drawn carts, and then delivered to customers.  Not only did they sell the sand, but their technical expertise was readily available for all customers, big or small, to help manufacture the best castings. After surviving The Great Depression, Carpenter Brothers, Inc. slowly increased the number of products it distributed and expanded its sales territory into what it is today.


Carpenter Brothers, Inc. has committed itself to its customer's success by providing exceptional service to go along with the superior products and equipment they supply.  With multiple warehouses around the United States we can get you the products you need when you need them. Our logistics team can handle getting your order to you by truck, plane, or train. Our technical sales and engineering staff all have experience in the industry, so when you buy from Carpenter Brothers you gain access to all of our knowledge.
