Hammer hollow core with RATIO thread
Flexible use with many 259 system components, such as drill adapters, extension pieces etc. / Extremely solid design for the most demanding applications / Manufactured of chrome- nickel-molybdenum steel which is used, among other things, for crankshafts and drive axles in the automotive industry / Particularly high impact strength carbide studs which also cut very well / High-temperature vacuum brazing at 1,120°C / 2-steps special high temperature treatment
The principle:
Interchangeability of all components in the drilling system / Any length of extension is possible by simply screwing together parts
System 259 product overview and example
Features
- Economic drilling in concrete, masonry and lightly reinforced concrete from ø35 to ø150mm diameter and to a depth of up to 2 metres
- Above-average tool life
- Smooth breakthroughs through concrete and masonry up to large diameters due to practical designs.
- The system can be extended as required by simply screwing together the 300 mm and 450 mm extension pieces
- It is recommended to grease the threaded bolts to ensure easy and non-destructive release of the components
- We recommend the thread grease for this (Item 259 008 010)
