Meet a drill built for precision deep-hole work: the Dormer Pramet A110 8.70 mm HSS ST Straight Shank Long Series Drill (DIN 340). Designed for performance where standard-length bits fall short, this long-series twist drill delivers dependable reach and consistent cutting action across a range of metals.
- 118-degree conventional point provides a strong, self-centering entry and is easy to re-grind, helping you maintain peak performance with minimal downtime.
- Steam oxide finish reduces built-up material on the cutting edge, minimizing friction and preventing chip adhesion for cleaner holes and longer edge life.
- Long length series enhances reach for deep holes and tight cavities, boosting accuracy in components with extended drilling depths.
- Premium HSS material handles drilling diverse materials—from steel and stainless steel to aluminum—without compromising rigidity or control.
- Straight shank (ST) design ensures secure grip in chucks and machine spindles, making it versatile for both handheld drilling and powered equipment.
- DIN 340 compliance aligns with standard tooling systems for reliable interchangeability in workshops and production floors.
Who benefits most: machinists, fabricators, and maintenance technicians tackling deep-hole tasks in metal enclosures, automotive components, brackets, and structural parts. When you need to drill deeper, stay on plan with predictable hole quality, clean entry, and minimal deflection—every time.
Practical application tips: start with a light pilot hole if material is particularly hard, use appropriate cutting fluid consistent with your material, and periodically re-sharpen the 118° point to preserve edge geometry for clean, accurate holes.
