Dormer Pramet A110 14.50 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

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.
