Dormer Pramet A110 5.75 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 5.75 mm HSS straight shank long series drill (DIN 340) is built for precision, longevity, and versatile metalworking performance. Designed for professional drills and demanding materials, this drill delivers a reliable, repeatable hole every time thanks to its carefully engineered geometry and premium construction.

What makes the A110 stand out

• 118-degree conventional point provides a robust cutting edge that resists wandering and maintains alignment, while offering ease of re-grinding when the edge wears—keeping downtime to a minimum in busy workshops.
• Steam oxide finish minimizes material sticking to the cutting edge, reducing pull-out and smear when drilling tough metals, and helping chips evacuate cleanly for smoother progress.
• Long length series delivers increased reach for deep holes and hard-to-access positions, making it ideal for fabrications, brackets, and assemblies where standard drills can’t reach.
• Premium HSS material handles a wide range of metals—from steel and stainless steel to aluminum—providing a dependable drilling experience across common workshop jobs without changing tools.
• DIN 340 straight shank geometry ensures solid grip and compatibility with common drill chucks, adapters, and machines, enabling consistent performance in both handheld and machine-controlled setups.

Ideal use cases and scenarios

• Drilling precise, deep holes in steel chassis, automotive components, and structural metalwork where standard-length drills don’t reach.
• Fabrication tasks requiring consistent hole size and smooth wall finishes in aluminum and stainless applications.
• Maintenance and repair work where quick regrinding of the tip extends tool life and reduces downtime.
• Handheld drilling on smaller machines or portable drills that benefit from a long-reach tool with dependable rigidity.

Practical guidance for best results

• Use proper feeds and speeds for the material: lighter feeds with aluminum, moderate to heavy feeds for steel and stainless to maintain courteous chip formation and edge life.
• Apply a suitable cutting fluid or lubricant to improve heat management and prolong edge life, especially during deeper hole drilling where heat buildup is higher.
• Secure workpieces firmly and consider pilot holes for stainless or harder steels to reduce walking and improve accuracy.
• For long holes, periodically retract the drill to break chips and prevent clogging, keeping cutting edges clean and effective.

The Dormer Pramet A110 5.75 mm HSS straight shank long series drill is a practical, durable choice for professionals who need a dependable drill that can reach deeper, perform consistently across common metals, and stand up to rigorous use in both handheld and machine environments. With its engineered tip geometry, protective finish, and versatile DIN 340 shank, this drill tackles a wide range of metalworking tasks with clarity and control.
