Dormer Pramet A110 6.70 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Engineered for depth and durability, the Dormer Pramet A110 6.70 mm HSS straight shank long-series drill (DIN 340) is built to conquer deep-hole tasks with precision and reliability. This drill bit combines a rugged 118-degree conventional point with a steam oxide finish, delivering a clean entry and reduced tendency for built-up material on the cutting edge.

Key features that matter in real work

• 118-degree conventional point — creates a strong, self-centering entry that's easy to re-grind when necessary, minimizing downtime in repetitive drilling tasks.
• Steam oxide finish — reduces sticking and built-up edge, helping chips evacuate smoothly and extending usable life on ferrous and non-ferrous materials.
• Long-length series — designed for deeper holes and applications where reach matters, letting you access recessed workpieces or thick assemblies without switching tools.
• Premium HSS material — versatile for drilling steel, aluminum, and stainless steel, delivering dependable performance across a range of metals in both handheld and machine setups.
• Straight shank, DIN 340 — compatibility with standard chucks and drill presses ensures solid, accurate performance in everyday fabrication and workshop environments.

Why this drill stands out in your toolbox

• For shops that routinely drill deep holes in metal components—engine brackets, gearbox housings, or thick plates—the A110 long-series drill provides reliable reach without compromising cutting efficiency.
• In handheld drilling, you’ll notice steadier starts and cleaner hole walls thanks to the precise 118° point and robust HSS core, reducing the need for rework.
• When used in a milling or drilling machine, the straight shank maintains consistent alignment, improving performance in production runs where speed and accuracy matter.

Ideal use scenarios

• Fabrication and repair work requiring deep, straight holes in steel, aluminum, or stainless steel.
• Automotive and industrial assemblies where long reach prevents repositioning or flipping parts mid-drill.
• DIY and workshop projects that demand dependable drilling performance across multiple metals with a single tool.

Practical tips for best results

• Keep the drill sharp; refresh the 118° point as needed to maintain a clean entry and precise hole alignment.
• Use appropriate lubrication or cutting fluid to manage heat, especially on stainless steel and thicker sections.
• Securely clamp workpieces to minimize runout and maximize hole accuracy when using a long-series drill.
• Match the speed and feed to the material being drilled, prioritizing steady, controlled cuts to extend tool life.
