PRODUCTS — LARGE-DIAMETER DRILLING
SMV Large-Diameter Modular Drills
Ø32–101 mm standard — up to 127 mm custom — with twin cutting edges that deliver up to 100% higher productivity than conventional modular drills of the same size.
- Ø32–101 mm · custom to 127 mm
- 5×D–10×D standard · 20×D custom
- Twin cutting edges — up to 100% faster
Double the Cutting Edge. Double the Output.
SMV combines the high feed and depth capability of modular drills with the speed of rigid bodies. Two full cutting edges work simultaneously — up to 100% higher productivity at the same diameter.
- Standard Ø32–101 mm; custom intermediate sizes to Ø127 mm
- 5×D–10×D from stock; custom bodies to 20×D and 1200 mm
- BTFL butterfly interface — two head types, one body system
- Center insert (SC3015 / SC3010) plus WCMT outer inserts
Built for Big Holes, Built Fast
SMV is engineered for large-diameter drilling where every minute of cycle time matters.
Twin Cutting Edges
Two complete edges in the cut — up to 100% higher productivity.
BTFL Interface
The butterfly interface accepts two head types on one body.
Spiral-Flute Bodies
Optional spiral flutes for better chip evacuation in cast iron.
Custom-Ready
Intermediate diameters to 127 mm, bodies to 1200 mm, regrindable center inserts.
Performance note: beyond 20×D, depth capability is application-dependent — our engineers will confirm feasibility.
Why Machinists Choose SMV
