The OSG Flat Bottom Carbide Drill with Through Coolant, 3xD, EGIAS Coated (4.53 mm) is built for high-precision flat-bottom holes in steel and alloys. Designed for machinists who demand reliability in demanding drilling tasks, it combines through-coolant efficiency with a durable coating for extended performance.

• Diameter: 4.53 mm
• Geometry: Flat-bottom design for accurate bottom-hole seating
• Length/Depth: 3xD length ratio provides greater drilling depth
• Coolant: Through-coolant delivery for efficient chip evacuation and cooling
• Coating: EGIAS coating enhances wear resistance and enables higher-speed operation
• Material: Solid carbide construction for rigidity and durability

The through-coolant system helps manage heat and evacuate chips, resulting in cleaner holes and longer tool life. The 3xD length supports deeper drilling in a single pass, while the EGIAS coating adds wear resistance for sustained performance in tough applications. Built from premium carbide, this drill delivers dependable rigidity and consistency for professional machining tasks.
