Key Benefits
- New diamond segments engineered for higher resistance and longer working life
- Higher diamond concentration (up to 2x) for improved cutting performance
- Titan-coated diamond segment design supports smoother, more effective drilling
- Corrugated segments improve rubble evacuation and reduce tool load
- Open segment design enables crown readiness for immediate use
- Forsheda seal helps support improved sealing performance during coring
Product Overview
The Diager L400 series core bit is built for professional contractors and installers requiring reliable drilling performance in hard aggregate and reinforced structures. Its improved segment design provides faster penetration, stable cutting, and reduced strain on both the coring machine and operator—especially during prolonged drilling.
Optimized for concrete and reinforced concrete applications, the L400 bit also performs on brick, granite, and stone. The corrugated segment geometry supports better debris evacuation, helping maintain consistent coring speed and minimizing binding.
Ideal Applications
- Concrete coring for plumbing, electrical, and mechanical penetrations
- Reinforced concrete drilling (including rebar contact)
- Brick and masonry opening for conduit and piping runs
- Stone drilling for construction and installation work
