Description
Experience precision and reliability with the OSG Flat Bottom Carbide Drill, crafted for high‑precision flat‑bottom drilling in steel and alloys. Featuring through coolant and a robust EGIAS coating, it balances depth, durability, and performance for demanding machining tasks.
- Diameter: 6.53 mm
- Geometry: Flat bottom design for true, clean bottom surfaces
- Cooling: Through coolant for efficient chip evacuation and cooling
- Length ratio: 3xD length for greater drilling depth
- Coating: EGIAS coating enhances wear resistance and durability
- Material: Solid carbide for rigidity and long tool life
- Applications: Optimized for drilling in steel and alloys with high accuracy
This drill delivers consistent hole quality with reduced heat buildup, thanks to its through‑coolant design and wear‑resistant coating. The combination of a flat bottom geometry and a 3xD reach makes it ideal for precision pockets and deep, clean holes in tough materials, while the carbide construction ensures reliable performance even under high‑speed machining.
