Flexovit 3/8 in. x 5/16 in. Ball carbide burs feature precision ground flutes crafted using advanced five-axis CNC fluting machines, ensuring exact control over tool geometry. This precision manufacturing process helps eliminate chatter and premature wear, enhancing the tool's durability and performance. Designed with a chisel tooth cutting pattern, these double cut carbide burs produce small, distinct granular chips instead of long sharp slivers. This unique cutting action prevents the loading of the bur’s flutes and minimizes chatter during use.
