OSG HP255-2165 Series HP255 5.50mm HY-PRO CARB Coolant Drill - TiALN Coated, Jobber Length, 5XD Carbide Drill Bit for Metalworking, CNC Machining & Industrial Applications

The HY-PRO CARB carbide drill series is an ideal blend of performance and cost-efficiency. Strong radial rake combined with precision point geometry and multi-layered coating makes this drill extremely versatile in application.

Negative Radial Rake - Stronger cutting edge to resist chipping

Refined honing on cutting edge - Provides more consistent performance from the first hole to the last hole

Multi-layered TiAlN Coating - Multiple layers provide superior resistance to thermal cracking from heat, versus other mono-layered coatings
