The OSG Flat Bottom Carbide Drill - Through Coolant 3xD - EGIAS Coated delivers precise flat-bottom holes in steel and alloys, built for reliability in demanding machining tasks. Its through-coolant design and 3xD length enable deeper holes with efficient chip evacuation and cooling.
- Diameter: 12.40 mm
- Drill type: Flat Bottom Carbide Drill
- Length ratio: 3xD for deeper drilling
