The OSG Flat Bottom Carbide Drill with through coolant is engineered for precise, flush-bottom holes in steel and alloys. Designed for durability and reliable performance, it’s ideal for machinists who need clean bottoms and repeatable results in demanding drilling tasks.

• Diameter: 9.30 mm
• Length-to-Diameter Ratio: 3xD for deeper drilling without sacrificing rigidity
• Through-Coolant: Through-coolant design for efficient chip evacuation and effective cooling during drilling
• Coating: EGIAS coating enhances wear resistance and enables higher-speed operation
• Material: Carbide construction for superior hardness and edge retention
• Application: Flat-bottom drilling to produce true, level bottoms in steel and alloys

Through coolant improves chip removal and cooling, helping maintain cutting edge sharpness and extend tool life. The flat-bottom geometry delivers true bottom surfaces for accurate pockets and seating features, while the 3xD length provides additional drilling depth without compromising stability. With the EGIAS coating, this drill supports higher speeds and longer-lasting performance in tough materials, making it a dependable choice for precision drilling in professional machining environments.
