With the innovative STEEL cut, PFERD has developed unique burs for steel and cast steel. These burs feature significantly increased aggressiveness and easy control for safe and precise work. Due to their incredibly high stock removal rate, STEEL cut burs help users save considerable time and money. Tree bur with radius end, shape F. 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
- Up to 50% higher stock removal rate on steel and cast steel in comparison to conventional double cut burs.
- Significantly increased aggressiveness, creates large chips, and has very good chip removal due to its innovative tooth design.
- Workpieces are protected due to significantly lower thermal load.
- The highly accurate concentricity enables precise work free from chatter marks. This considerably reduces wear on the bur and power tool or machine.
Recommendations for use
- Use the burs on powerful power tools with elastically mounted spindles to avoid unwanted vibration.
- Observe the recommended rotational speed.
- The smaller the bur diameter is in the area being used, the higher the recommended rotational speed can be.
- 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
- Very high speeds can cause discoloration on the shank. This does not constitute a safety risk.
- 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.
