5/16" Tuff-Cut™ Solid Tungsten Carbide Bur, 5/16" Head Diameter, 1/4" Shank Diameter, 1/4" Flute Length, 1 Each

These precision burs are crafted from metallurgically inspected tungsten carbide blanks and durable steel shanks, ensuring superior performance and longevity. Featuring sectional end cuts, these burs provide usable flutes on all end-cut designs for versatile cutting. The hydrogen atmosphere brazed-on shanks enhance reliability, making them ideal for burring applications on heat-treated and tough alloy steels. A combination of right-hand and left-hand helical flutes creates a chisel-type cutting tooth, delivering faster stock removal with reduced chatter and bounce. The double-cut design produces fine, granular chips for smoother operation compared to traditional single-cut burs. Good for high-performance, high-precision tasks.
