DeWalt HSS E Cobalt Drill Bit 5.2 mm – set of 10

DeWalt HSS E Cobalt Drill Bit 5.2 mm – set of 10 are high-speed steel cobalt drill bits designed for drilling metal and other industrial materials. Each bit has a 5.2 mm cutting diameter and is supplied in a bulk set of 10, suitable for workshop environments and professional use. The HSS E cobalt alloy increases hardness and maintains cutting performance at higher temperatures compared with standard HSS bits, enabling longer tool life when working with hardened steels and abrasive metals. These bits are compatible with handheld drills and drill presses and are intended for tasks that require reliable metal-drilling performance.

Advantages

HSS E cobalt construction provides improved heat resistance and wear performance, reducing the frequency of bit replacement during continuous or demanding drilling operations. The 5.2 mm diameter offers a common size for through-holes, pilot holes and metal fabrication tasks. Supplied as a set of 10, this product ensures availability of spare bits for repeated operations and reduces downtime. The bits are suitable for use in both handheld and bench drilling equipment, providing versatility in workshop and site applications.

Suitable for

• Drilling mild to hardened steels and other ferrous metals
• Metal fabrication and maintenance work
• Production environments requiring multiple identical bits
• Workshop and on-site drilling with handheld drills or drill presses

Key specifications

• Material: High-speed steel with cobalt alloy for enhanced heat resistance
• Cutting diameter: 5.2 mm
• Quantity: Set of 10 drill bits
• Intended use: Metal and industrial material drilling
• Compatibility: Suitable for handheld drills and drill presses

How to use

Secure the appropriate drill bit in the chuck of a handheld drill or drill press, ensuring it is centered and tightened. Mark and, if needed, center-punch the drilling location on the workpiece to prevent walking. Use appropriate cutting speeds and feed rates for the metal being drilled; reduce speed for harder or heat-sensitive materials. Apply cutting lubricant or coolant when drilling stainless or hardened steels to extend bit life and improve chip evacuation. Clear chips frequently and allow the bit to cool between prolonged cuts to maintain cutting performance.

Usage recommendations

For optimal performance, use recommended drilling speeds for cobalt HSS bits and apply cutting fluid when working with stainless or high-strength steels. Store the set in a dry place and replace worn bits to maintain hole quality and operator safety.
