Cut burs designed for use on hard titanium alloys

Pferd Inc. has introduced Titanium cut burs, designed for machining hard titanium alloys with tensile strength greater than 500 N/mm2. The double-cut bur’s tooth geometry generates stock removal rates up to 60 percent higher than conventional cross-cut burs, the company states.

Suitable for electric or pneumatic straight grinders and automated equipment, the burs can be used for milling, chamfering, contouring, and weld dressing, as well as applications on structural components, thin-walled tubing in chemical processing, and components requiring extremely high corrosion resistance.

Recommended cutting speed is 850 to 1,500 SFPM. The cut burs are available with a 3/8-in.-dia. cutting head and 2-1/2-in. length and a ½-in.-dia. cutting head with 2-3/4-in. length. Both have a shank diameter of ¼ in. Rotational speed is up to 14,000 RPM for the 3/8-in. model and 12,000 RPM for the ½-in. model.
