Dnipro-M 13-Piece M35 Cobalt Drill Bit Set (1.5mm – 6.5mm)

Product Overview
Engineered for extreme durability and precision, the Dnipro-M 13-Piece Cobalt Drill Bit Set is the ultimate solution for drilling through hard metals. Crafted from premium M35 High-Speed Steel with 5% Cobalt (HSS-Co), these bits are specifically designed to maintain their hardness and cutting edge at high temperatures. Whether you're working with stainless steel, cast iron, or heat-treated alloys, these bits deliver superior performance where standard HSS bits fail.

Technical Specifications

What’s Inside the 13-Piece Set:

• Metric Sizes: 1.5, 2.0, 2.5, 3.0, 3.2, 3.5, 4.0, 4.5, 4.8, 5.0, 5.5, 6.0, 6.5 mm.

Key Features

• M35 Cobalt Construction: The 5% Cobalt alloy provides exceptional heat and abrasion resistance, extending tool life by up to 10X in hard-metal applications.
• 135° Split Point Tip: Starts cutting on contact without "walking" or skating, eliminating the need for a center punch and reducing required feed pressure.
• Precision Ground Flutes: Fully ground spirals ensure fast chip removal and reduce friction for cleaner, more accurate holes.
• Extreme Heat Resistance: Designed to operate at higher speeds and withstand the intense heat generated when drilling stainless steel and hardened alloys.
• Industrial Strength: Heavy-duty web construction provides additional strength to prevent bit breakage under high-torque loads.
