DRILL SET METRIC 25 PCE COBALT S3

The Sutton Tools® HD-Cobalt Metric 25-Piece Drill Set (S3) is built for industrial performance, delivering superior strength and reliability when drilling the toughest materials. Engineered with 5% cobalt high-speed steel (HSS-Co), these jobber drill bits offer outstanding heat resistance and durability—ideal for cast iron, bronze, hardened steel, stainless steel, and other high-tensile metals.

A thick core design enhances rigidity for stable drilling in hard materials, while the 135° split point (for sizes above 2mm) ensures precise starts, reduced wandering, and lower drilling pressure. Housed in a durable plastic index case, this set covers 1.0mm–13.0mm for full versatility in workshop and industrial applications.

Features:

• 135° split point (>2mm & >3/32") for accurate positioning and reduced thrust

• Thick core for enhanced rigidity in demanding materials

• Precision parallel shank ensures accurate, consistent hole sizing

• HSS-Co (5% cobalt) for exceptional heat and abrasion resistance

• Colour-tempered finish for easy cobalt drill identification
