Description

Double cut burs are cross cut and ideal for machining cast iron, steel, stainless steel (INOX), nickel-based alloys, and titanium alloys. These burs have a high stock removal rate.

Universal line burs are designed for fine and coarse stock removal on the key materials used in industrial manufacturing. They provide a good stock removal rate and are not specific to a particular material.

Cylindrical bur

Advantages
  • Good stock removal rate due to high quality tungsten carbide, bur shape, cut, and optional coating.
  • Durable.
  • The highly accurate concentricity enables precise work free from chatter marks. This considerably reduces wear on the bur and power tool or machine.
  • High surface quality.
Recommendations for use
  • For the most cost-effective bur use, work with higher rotational/peripheral speeds. For burs with a 1/4" shank diameter, use power tools with a power output from 300 watts.
Safety notes
  • For safety reasons, the maximum application speeds with contact with the workpiece require a reduction in the recommended speed of tungsten carbide burs with standard shanks. Observe the reduced speeds outlined in the product details.
  • When working with longer shanks, it is crucial that the bur is in contact with the workpiece (or inserted in the hole or slot to be machined) before the power tool is turned on. As a rule, the bur must remain in contact with the workpiece for as long as the machine is running. Failure to observe this procedure may result in shank failure (bending) and hence an increased risk of accidents. If continuous contact between the tool and the workpiece is not guaranteed during use, the maximum idling speeds must not be exceeded.
  • Not designed for robotic or stationary applications due to risk of bending. Use only rigid clamping systems/power tools.
