P&N by Sutton HSS Cobalt Metric Drill Set w/ Bonus Countersink - 25 Piece

The P&N by Sutton 25 Piece Cobalt Drill Set is the heavy-duty answer for drilling hard, abrasive materials that destroy standard bits. Enriched with Cobalt for superior heat resistance, these bits cut through stainless steel and cast iron without softening or dulling. The set is thoughtfully curated with extra quantities of the most commonly used sizes (3, 4, and 5mm) and includes a bonus 16.5mm countersink, ensuring you have everything needed to drill and finish holes neatly in a single durable case.

Features:

Heavy Duty Cobalt Formula: Manufactured from High-Speed Steel containing Cobalt, which significantly improves abrasive resistance and strength, allowing the bit to maintain its edge in high-temperature applications like drilling stainless steel.
135° Split Point: Features a self-centering 135-degree split point that bites into the material immediately, preventing the bit from "walking" and enabling 50% faster drilling with less feed pressure.
Bonus Countersink Included: Comes with a 16.5mm HSS Countersink, allowing you to deburr the hole and recess screw heads flush with the surface immediately after drilling, without searching for a separate tool.
Duplicate Popular Sizes: Includes two of each of the most common sizes (3mm, 4mm, and 5mm), ensuring that if you snap or lose a bit during a critical job, you have a backup ready to go.
Versatile Application: While optimized for hard metals, the geometry is also perfectly suited for drilling brass, aluminium, wood, and plastic, making it a comprehensive all-rounder for portable and pedestal drills.
