Brazing Department

Mastercut Tool in Safety Harbor, FL employs some of the most dynamic machinery and personnel in the industry in our carbide bur brazing department.

Brazing is the process in which a tri-metal wafer is inserted in-between the shank and the head of a bur. The bur blank is heated to melt the wafer, and when it solidifies, the carbide head of the bur is permanently affixed onto a steel shank. Key elements to getting a good braze are cleanliness, consistent materials, consistent brazing temperatures and timing, and accurate centering devices.

To cover all of these critical elements, our brazing department uses automated CNC brazing equipment in a clean, controlled environment. With this system and their knowledge and experience, they can produce thousands of high quality parts per day. Our engineers and maintenance teams have completely customized their machines and their procedures to optimize the bur brazing process to ensure solid braze integrity and tight concentricity.

The members of our brazing team also run a battery of quality control tests to measure braze strength and tool concentricity (the photo shown below is a hydraulic destructive test). If any questionable items surface during any of the tests, then the entire lot is tested before the burs can proceed to the next operation.

Our brazing team has achieved 99.99% braze integrity success rate based on actual customer use. This means that less than one bur per 10,000 experiences a braze failure during actual use. We are proud of the engineering challenges they have overcome over the years and the innovations they have created to give our customers world-class burs. We respectfully present them as a testimony to our teamwork and devotion to giving you only the best!
