Dormer Pramet A110 5.60 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Discover precision and reach in one reliable drill with the Dormer Pramet A110 5.60 mm HSS ST Straight Shank Long Series Drill DIN 340. Engineered for demanding metalworking tasks, this bit pairs a robust cutting geometry with a long flute design to tackle deeper holes without compromising hole accuracy.

• 118-degree conventional point delivers a strong, self-centering entry and resharpens cleanly, helping you maintain true holes even after multiple regrinds.
• Steam oxide finish reduces friction and minimizes adhesion of workpiece material to the cutting edge, promoting smoother chip evacuation and cleaner cuts.
• Long length series provides extended reach for deeper holes and applications where access is limited or distances are greater than standard bits allow.
• Premium HSS material offers versatile performance across a range of metals—from steel and aluminum to stainless steel—making it a reliable choice for mixed-material projects.
• Straight shank ensures compatibility with a wide array of chucks and turning centers, making it suitable for both handheld drilling and machine operations.
• DIN 340 specification guarantees consistent sizing and interchangeability with common tooling setups in professional workshops.

What makes this drill stand out is its smart balance of toughness, reach, and compatibility. The A110’s long series design minimizes deflection when drilling deep holes, helping you maintain straight, accurate drill paths in thick workpieces. The 118-degree point reduces wandering at entry, so you can start holes confidently in challenging materials. And with the steam oxide finish, you’ll experience improved chip control and easier cleanup after completing a job.

Best suited for professional shops, maintenance teams, and fabrication work, the Dormer Pramet A110 drill shines in scenarios like drilling deep pilot or through-holes in steel plates, fabricating aluminum components with precise hole alignment, or preparing fastener holes in stainless steel assemblies where reach matters as much as precision.

Practical use tips to get the most from this long-reach drill:

• Secure the workpiece firmly and use a suitable clamp or vise to minimize deflection during deep-hole drilling.
• Start with a light, controlled feed to establish a clean entry and prevent chip packing at depth.
• Use appropriate lubrication or cutting fluid to extend tool life and improve surface finish, especially on harder materials.
• Keep the drill perpendicular to the work surface to avoid angled holes; regrind the point as needed to maintain sharpness and accuracy.
• Match your speed and feed to the material being drilled and the depth of the hole—adjustments may be required for steel, aluminum, or stainless steel to optimize chip evacuation and cutting efficiency.
