Dormer Pramet A110 18.00 mm HSS Straight Shank Long Series Drill DIN 340

When you need to reach deeper without sacrificing edge life, the Dormer Pramet A110 18.00 mm HSS ST Straight Shank Long Series Drill DIN 340 is your dependable workhorse. Its 118-degree conventional point delivers a strong, self-centering tip that bites cleanly into a variety of materials and remains easy to re-grind, keeping downtime to a minimum.

The steam oxide finish minimizes sticking and built-up edge at the cutting edge, promoting smoother starts and steadier hole quality even in challenging workpieces. Designed as a long-length drill, it provides increased reach for deep holes and through-holes where access is limited—perfect for thick plates, assemblies, and recessed features.

Constructed from premium high-speed steel (HSS), this drill handles a broad range of materials, including steel, aluminium, and stainless steel, with reliable durability and performance. The straight shank ensures broad compatibility with common hand-held drills and drill presses, delivering stable runout and predictable hole geometry. DIN 340 dimensional standards mean consistent sizing and easy interchange with other tooling in your shop.

Key features at a glance

• 118° conventional point: strong, self-centering tip that’s easy to re-sharpen when wear sets in.
• Steam oxide finish: reduces built-up edge and sticking for smoother starts and better chip evacuation.
• Long length series: extended reach for deeper holes and tight workpiece access.
• Premium HSS material: versatile drilling across steel, aluminium, and stainless steel.
• Straight shank: broad compatibility with standard chucks and machines.
• DIN 340: precise, interchangeable dimensions for reliable performance.

Ideal uses and scenarios

Perfect for workshop environments that require deep-hole capabilities without swapping tools. Use this drill for fabricating and maintaining machinery, automotive components, and general engineering tasks where through-holes or long-reach drilling are essential. The re-grindable tip keeps the tool productive longer—when the edge dulls, restore the point and return to work without replacing the bit.

Practical tips for optimal results

• Match speed and feed to the material: use conservative speeds for aluminum to minimize built-up edge, and moderate speeds for steel to maintain a clean cutting action.
• Utilize appropriate cooling to control heat buildup and extend tool life, especially on stainless steel.
• Periodically re-sharpen the 118° point to maintain optimal penetration and hole accuracy.
• Ensure proper workpiece clamping and alignment to minimize deflection and ensure straight, true holes.
