The Dormer Pramet A110 14.50 mm HSS straight shank long series drill is built for precision, reach, and dependable performance across a wide range of metals. Designed to DIN 340 specifications, this drill combines a robust substrate with a geometry that stays sharp through repeated work, making it a smart choice for professional workshops and demanding fabrication tasks.

Why this drill stands out

• 14.50 mm diameter with a conventional 118-degree point for clean initial penetration and easy re-grinding when needed, helping you maintain accuracy over time.
• Steam oxide finish minimizes built-up edge by reducing friction, so material tends not to smear or cling to the cutting edge—extending tool life and keeping holes consistent.
• Long length series delivers increased reach for drilling deeper holes and accessing recessed or hard-to-reach work areas without sacrificing rigidity.
• Premium HSS material suitable for drilling a variety of metals including steel, aluminum, and stainless steel, providing versatility in mixed-material projects.
• Straight shank (DIN 340) ensures broad compatibility with common drill chucks and holders, making it easy to drop into existing setups, whether in handheld or machine drilling.
• Versatility in one tool ideal for a range of applications—from automotive fabrication and metal fabrication to DIY metal projects—where deep-hole drilling and reliable edge retention matter.

Practical uses and how it helps you

• For thick workpieces, this drill’s long length lets you reach through multiple layers without flipping to a shorter tool, reducing setup time and tool changes.
• When drilling stainless steel or aluminum, the steam oxide coating helps maintain a clean cutting edge, producing smoother holes with fewer passes.
• In hand-held drills or CNC-compatible fixtures, the DIN 340 straight shank ensures stable feed and consistent hole geometry, reducing runout and improving drilling accuracy.
• Perfect for repeated drilling on steels and alloys where you need to balance durability with the ability to re-sharpen the tip when it starts to dull.

Tips for best results

Match cutting speed to the material, use steady feed pressure, and apply a suitable cutting fluid or coolant to minimize heat buildup. Start with a light pilot hole if the material is particularly tough, then progress to the full 14.50 mm diameter. After use, inspect the edge for built-up material and re-sharpen as needed to maintain precision on future projects.

Whether you’re outfitting a machine shop or tackling a demanding DIY project, the Dormer Pramet A110 long series drill provides reliable depth, edge retention, and compatibility with a broad range of materials, making it a dependable workhorse in any metalworking toolkit.
