- Universal use
For all conventional power tools depending on diameter: 115-230 mm for dry cutting on angle grinders and wall chasers 300-400 mm with 20, 22.2 and 25.4 mm holes for dry or wet cutting on floor saws and bench saws 300 and 350 mm with 30 mm hole and 25.4 mm reducing ring feature a silent-core main blade, therefore used exclusively for wet cutting on bench saws
A newly developed generation of diamond discs with superb cutting performance and speed as well as excellent service life. The symmetrically arranged diamonds are integrated throughout the segment in four layers, which gives the disc an unprecedented cutting speed and an extremely comfortable cutting feel even in the toughest stone materials and also in iron. Laser-welded with a segment height of 12 (10+2) mm, with a segment height of 15 (13+2) mm for sizes of 230 mm and larger.
Advantages
- Pure diamond quality with a hardness level of 10 ensures maximum performance:
- Maximum cutting speed in concrete, reinforced concrete, exposed aggregate concrete as well as in granite and other hard natural stones.
- Maximum service life due to 15 mm high segments (diameter 115-180 mm: 12 mm). With the exception of a 2 mm diamond-free zone ("base"), the segments can be processed with the same maximum performance.
- Maximum working comfort due to cobalt-based bond. The selected base material ensures a smooth cutting feel and smooth immersion into the stone being cut without exerting pressure on the power tool.
- Clear production processes ensure consistent quality!
Advice
- The small diameters of 115 and 125 mm have a hole of 22.23 mm, as well as the new X-Lock mount for the latest generation of angle grinders. They can therefore be used on all conventional power tools as well as on the new X-Lock power tools.
- All discs with a 25.4 mm hole have an additional drive hole.
- The discs with a 30 mm hole and a 25.4 mm reducing ring feature a silent core ("silentio") main blade and can therefore only be used for wet cutting on bench saws.
