Adjustable large diameter drill with cartridge
- Drill diameter can be adjusted by changing setting plates. SCM440
- The same inserts as the TungdrillTwisted or the TungSixDrill
can be used.
This simplifies inventory control.
- By exchanging cartridges, the drill body maintains a S45C
long tool life even if the insert seat is damaged.

Highly rigid body and optimized insert position No chip control difference with or without setting plates.
This ensures stable machining in each diameter range.
- Provides well balanced cutting forces and stable machining
conditions for highly accurate hole making. Drill : TDBU2461-2579-2.5 Cutting speed : Vc = 410 SFM
- Creates small chips and allows excellent chip evacuation. Insert : XPMT08T308R-DJ Hole depth : H = 2.75"
