Premium diamond cutting disc specially developed for all construction trades with enormous versatility, extremely high service life and maximum cutting speed. The perfect disc for all angle grinders, wall slitting cutters, hand-held and floor saws.

Maximum cutting speed and extremely clean and precise cutting edges

Special segment shape and innovative segment technology

Long service life

Up to 15 mm high segments

Optimised dust removal and cooling

Specially shaped innovative fan segments feed in cooling air and transport the dust out of the cut. Special cooling openings with an arrow arrangement serve as additional cooling and as a captive running direction indicator.

Smooth running and pleasant working conditions

The special innovative slot geometry reduces uncontrolled vibrations and unpleasant running noises.

Protection against undercut, especially when working with particularly abrasive materials

Specially arranged protection segments with a disc diameter of 115 to 150 mm

  • Diamond cutting discs become blunt at excessively high rotation speeds and wear too rapidly at insufficient circumferential speeds

  • If ease of cutting is lost (indicated by heavy sparking), resharpen the disc in abrasive material, e.g. sandstone, with several cuts

  • Separate larger workpiece cross-sections into several sections (swing cut)

  • Work without applying pressure — the weight of the machine is sufficient. Increased pressure causes increased wear.

  • Diamond cutting discs are designed for straight cutting. Cutting curves deforms the blade and results in core cracks and segment tear-offs — risk of injury!

  • Despite the level of safety offered by the tool, always wear safety glasses and clothing while working

  • Observe the information on the label (max. rotation speed), the restrictions of use and the safety instructions

  • The direction arrow on the disc must match the machine's direction of rotation

  • Must not be used for lateral grinding

  • Use the appropriate protective hood

  • Clamping must be performed only by a trained specialist (do not use force, use clean clamping flanges of the same size, perform a test run)

  • If grinding tools are clamped wrongly or used incorrectly or are damaged, they represent a danger and may cause serious injury
