Dormer Pramet A110 5.00 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 5.00 mm HSS ST Straight Shank Long Series Drill DIN 340 is engineered for serious metalworking tasks where depth and precision matter. With a robust HSS composition and a carefully designed geometry, this drill delivers dependable performance from first hole to last, even in challenging materials.

• 118° conventional point provides a strong, self-centering bite that starts cleanly and stays true. The geometry also makes re-grinding straightforward, helping you extend the life of the tool without sacrificing accuracy.
• Steam oxide finish reduces friction and minimizes material sticking to the cutting edge, helping to prevent built‑up edge and deliver smoother chip evacuation during deep drilling.
• Long length series is designed for deeper holes and applications where reach is critical. The extended flute length maintains rigidity while providing the extra depth you need without compromising hole quality.
• Premium HSS material handles a variety of substrates—from standard steel to aluminum and stainless steel—while maintaining solid drills with consistent diameters and reliable performance across jobs.
• Versatile straight shank compatibility means this drill works seamlessly with handheld drills and machine spindles alike, offering dependable seating and minimal runout in a wide range of setups.
• DIN 340 compliance ensures compatibility with standard workholding and tooling interfaces, simplifying integration into existing tooling inventories.

Who benefits most: machinists, fabricators, and maintenance professionals who routinely drill deep holes in metal, as well as DIY enthusiasts tackling demanding projects where accuracy and reach matter. The A110 5.00 mm drill is ideal for through-holes in steel, stainless, and aluminum, where clean starts, controlled feeds, and reliable tool life are non-negotiable.

Practical tips for best results:

• Use a steady, moderate feed rate and maintain consistent cutting speed to maximize life and hole quality.
• Let the drill cut without aggressive plunging; start with a center mark to ensure accurate entry.
• Apply light lubrication or cutting fluid for stainless and high-strength steels to reduce heat and wear.
• Re-sharpen or replace when you notice increased chatter or gradual deviation in hole diameter.
