Dnipro-M 19-Piece M35 Cobalt Drill Bit Set (1.0mm – 10.0mm)

Product Overview
The Dnipro-M 19-Piece Cobalt Drill Bit Set is a professional-grade solution engineered for drilling through the toughest metals. Crafted from premium M35 High-Speed Steel with 5% Cobalt (HSS-Co), these bits offer extreme heat and abrasion resistance. Specifically designed for drilling stainless steel, cast iron, and high-tensile alloys, this set provides superior performance and longevity where standard HSS bits fail.

Technical Specifications

What’s Inside the 19-Piece Set:

• Metric Sizes: 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, 10.0 mm.

Key Features

• Industrial M35 Cobalt Alloy: Formulated with 5% Cobalt to maintain cutting edge hardness even at high temperatures, extending tool life by up to 10X in hard-metal applications.
• 135° Split Point Tip: High-performance tip starts cutting immediately on contact without "walking" or skating, eliminating the need for a center punch.
• Precision-Ground Flutes: Fully ground spirals ensure rapid chip evacuation and minimize friction for cleaner, more accurate holes.
• Extreme Heat Resistance: Engineered to withstand the intense heat generated when drilling through Inox (Stainless Steel) and hardened structural steels.
• Reinforced Web Design: Heavy-duty internal core provides extra strength to prevent bit breakage during high-torque operation.
