Popular DeWalt Products

DeWalt's HSS drill bit range includes versatile jobber drill bit sets covering the most frequently used sizes from 1mm to 13mm, ideal for keeping in your van or workshop. Individual replacement bits are available for those specific sizes you use most often. For specialist metalworking applications, DeWalt offers cobalt-enhanced HSS bits that provide superior heat resistance when drilling stainless steel and other tough alloys. Their stepped drill bits are perfect for electricians and sheet metal workers, allowing multiple hole sizes from a single bit whilst delivering clean, burr-free edges in thin materials.

Frequently Asked Questions

What materials can I drill with DeWalt HSS drill bits?

DeWalt HSS drill bits are designed primarily for drilling metal including mild steel, aluminium, copper, and brass. They're also highly effective in wood, plastic, and composite materials, making them versatile additions to any toolkit.

How do I extend the life of my DeWalt HSS drill bits?

Always use appropriate cutting speeds for the material being drilled—slower speeds for harder metals. Apply cutting lubricant when drilling steel to reduce heat and friction. Ensure bits are sharp and replace them when dull, as forcing a blunt bit generates excessive heat and causes premature failure.

What's the difference between standard HSS and cobalt HSS bits?

Cobalt HSS bits contain a percentage of cobalt alloyed into the steel, providing significantly improved heat resistance and hardness. This makes them ideal for drilling harder materials like stainless steel and cast iron where standard HSS bits would quickly lose their edge.
