High-performance tungsten carbide burs, TOUGH cut, Cylindrical bur with radius end – Shape C

Technical information

PFERD Carbide Bur SC-3L6 Cylindrical Radius End TOUGH DC 3/8" x 3/4" x 1/4" Shank

The TOUGH cut has been specially designed for tough operating conditions such as in shipyards, foundries and steel construction. It is also ideal for all demanding production environments where frequent tooth breakages and other damage to conventional burs occur. Cylindrical bur with rounded radius end, shape C. Tungsten carbide burs with extended shanks are ideal for efficiently machining small, hard-to-reach areas. The shanks can be shortened if required. This bur has a long steel shank.

Special features

• The highly accurate concentricity enables precise work free from chatter marks. This considerably reduces wear on the bur and power tool or machine.
• Innovative quick-mounting system guarantees convenient handling and cool grinding
• Minimized tooth chipping/breakage, splintering, and bur failures due to very robust, high-performance cut.
• Can also be used at a lower rotational speed.
• Due to their extreme impact resistance, they are an ideal option when an extended-shank bur is needed.

Recommendations for use

• Observe the recommended rotational speed.
• The TOUGH cut can be used on materials up to 580 HV (54 HRC). For hard materials, it is recommended to test the bur on the same material before using on the actual workpiece.
• TOUGH cut carbide burs are also designed for high-impact applications when using shank extensions, for applications with a high surface contact angle, for work on narrow contours, and for applications where slower rotational speeds are used.
• 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.
