High speed and outstanding free cutting in very hard concrete and stone. The segment shape helps the mud evacuation and provides less friction. For motors from 1.5 kW.
82 mm / 3.23 "
The revolutionary technology Diagrip™ ensures an optimal 3D diamond distribution. The result is superior drilling capacity, longer life and smooth, rapid drilling.
The standard core lengths are 450 mm and 500 mm (CR128), but other tube lengths are available on request.
In addition to the standard diameters, other diameters are available upon request.
This extensive series covers most applications, and customised tools can be arranged upon request.
The segments are firmly fixed on the steel tube, notched into the tube and a high-resistance solder is used.
The segment edge design helps to centre the bits in order to give a smooth and fast start. This is especially useful when drilling in walls and/or with big diameters.
Low active surface and evenly distributed cutting edges reduce the friction, which results in a faster drilling.
The notch design of the segments provides efficient cooling of the core bit and evacuates the abrasive slurry, which increases the life and speed.
With accessories such as adapters, centering devices and extenders the drill job can be made easier.
Easy drilling with high speed.
