Dormer Pramet A110 11.00 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 11.00 mm HSS ST Straight Shank Long Series Drill, DIN 340, is crafted for deep, accurate holemaking in metalworking environments. Built to handle demanding materials while staying easy to re-sharpen, this drill delivers reliable performance when reach matters as much as precision.

Key features that deepen your drilling capability

• 118° conventional point: A robust, self-centering tip that starts cuts cleanly and can be re-ground to extend tool life without sacrificing accuracy.
• Steam oxide finish: Helps reduce workpiece material adhesion to the cutting edge and promotes smooth chip flow for cleaner holes and less friction.
• Long length series: Extended reach for deeper holes and hard-to-reach pockets, maintaining rigidity and stability in handheld or machine drilling setups.
• Premium HSS material: A versatile high-speed steel composition suitable for drilling steel, aluminum, and stainless steel with dependable wear resistance.
• Straight shank (DIN 340): Compatible with standard chucks and collets, enabling secure seating in both handheld drills and milling machines.

Ideal use cases and practical guidance

Perfect for fabricators, pattern makers, and maintenance technicians, the A110 excels wherever you need a deeper hole with consistent diameter. Use it for:

• Thick metal plates, structural steel, and alloy components where standard-length drills fall short
• Automotive and machinery housings that require precise, through-hole access
• Prototype work or production fixtures that demand repeatable hole depth and finish

Why this drill stands out from the pack

Many long-series drills trade off rigidity for reach, but the A110 design balances both. The 11.00 mm diameter coupled with a durable HSS composition delivers dependable performance across a range of materials, while the 118° point minimizes wandering on entry and reduces the need for frequent centering. The steam oxide coating further reduces sticking and improves chip evacuation, helping you maintain feed rates and surface finish even on tougher workpieces.

Pro tips for top results

• Apply a light cutting fluid or lubricant to extend tool life and improve finish, especially on stainless steel.
• Use a measured peck-drill approach to clear chips when drilling deep holes to prevent clogging and heat buildup.
• Keep the drill sharp; re-sharpen the point when you notice increased wandering or slower cutting performance.
• Match your speed and feed to the material: higher speeds for aluminum, moderate speeds for steel, and cautious feeds for stainless steel to avoid work-hardening.

DIN 340 compatibility ensures seamless integration with a wide range of drilling setups, making the Dormer Pramet A110 11.00 mm HSS Straight Shank Long Series Drill a dependable choice for both handheld and machine-driven applications.
