Ball-Nosed Cone Burs (SL)
Available91 products
Ball-nosed cone burs (SL) contour surfaces and debur and finish tapered openings with a round bottom. The long, cone-shaped head fits into narrow angles, tight spots, and areas that are difficult to access. Cone-shaped burs have straight tapered sides for smoothing beveled and chamfered surfaces, while the short cutting area maneuvers into counterbored holes. Cutting edges are made from carbide, which is a hard material that resists wear and limits heat. Carbide burs attach to rotary power tools such as die grinders, high-speed engravers, and pendant drills.
Double-Cut Ball-Nosed Cone Burs
Double-cut ball-nosed cone burs (SL) have crossing left- and right-hand flutes to quickly remove stock from steel, stainless steel, and other high-strength ferrous metals while leaving a smoother finish than single-cut burs.

Single-Cut Ball-Nosed Cone Burs
Single-cut ball-nosed cone burs (SL) have parallel rows of right-hand spiral flutes to balance stock removal and finish. Single-cut burs are used in general applications to evacuate chips on most materials, including brass, copper, cast iron, and steel.

Steel-Cut Ball-Nosed Cone Burs
Steel-cut ball-nosed cone burs (SL) make aggressive cuts in steel and hardened steel. Large chips are removed quickly to keep surface temperatures low to reduce annealing that can cause workpiece discoloration.
