Dormer Pramet A110 13/32 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 13/32 Inch HSS ST Straight Shank Long Series Drill (DIN 340) is engineered for serious depth work without sacrificing precision or versatility. Designed to cut through a range of materials with reliability, this drill bit pairings a robust build with practical geometry for real-world drilling tasks.

Key features that matter in the workshop

• 118° conventional point — a strong, self-centering tip that resists wandering and is easy to re-sharpen, helping you maintain a true hole without repeated adjustments.
• Steam oxide finish — a anti-stick coating that minimizes built-up edge and workpiece material on the cutting edge, leading to smoother starts and cleaner holes.
• Long length series — optimized for drilling deeper holes and reaching into tight or recessed areas where standard bits can’t reach.
• Premium HSS material — versatile enough for drilling steel, aluminum, and stainless steel, delivering dependable performance across common workshop metals.
• Straight shank design — broad compatibility with a wide range of machine chucks and hand-held drills, simplifying tool changes and minimizing runout.
• DIN 340 compliant — built to standard specifications, ensuring reliable interchangeability with other DIN 340 tooling for consistent results.

Ideal use cases

• Producing deep holes in steel components, chassis parts, and structural members where standard-length bits fall short.
• Holes in aluminum or stainless steel where clean entry and reduced friction are valued for precision work and better surface finishes.
• Hands-on workshop projects and machine drilling alike—this bit performs reliably in benchtop mills, drill presses, or handheld drilling setups.
• Maintenance and fabrication tasks that require a single versatile drill bit you can rely on across multiple materials without switching tooling.

Why this drill makes sense for serious work

Rather than chasing a collection of specialty bits, the Dormer Pramet A110 Long Series consolidates depth, durability, and compatibility into one reliable solution. Its 13/32 inch diameter is a practical choice for mid-scale holes, keeping material removal efficient while preserving workpiece integrity. The combination of a tough HSS core, an edge-friendly steam oxide finish, and a geometry that supports easy regrinding means you’ll spend less time sharpening and more time drilling.

Practical tips for best results

• Match the drill speed to the material—significantly higher speeds for aluminum, moderate speeds for steel, with appropriate lubrication to extend cutting life.
• Let the bit do the work—steady feed pressure minimizes deflection and produces straighter holes, especially in deeper drilling tasks.
• When regrinding, preserve the original 118° point to maintain predictable starts and cutting performance.
• Use appropriate clamping and support for long-hole drilling to control chatter and ensure hole accuracy.

What you gain

With the Dormer Pramet A110, you’re choosing a drill that combines depth capability with universal compatibility, delivering dependable performance across common workshop metals. It’s a practical, no-nonsense solution for professionals and DIYers who value consistent hole quality, reduced risk of snags or edge build-up, and the flexibility to tackle projects that demand both reach and precision.
