Description
The Dormer Pramet A110 6.75 mm HSS ST Straight Shank Long Series Drill (DIN 340) is purpose-built for deep-hole drilling with dependable performance across a range of metals. Its 118° conventional point delivers a strong, self-centering start and remains easy to re-sharpen, so you spend less time resharpening and more time drilling. This long-series drill is specifically designed for extended reach, making it the go-to choice when you need to access deeper holes without sacrificing precision.
- DIN 340 long-series design ensures compatibility and consistency across standard tooling, with a straight shank that fits a wide array of hand-held and machine drilling equipment.
- 118° conventional point provides a robust entrance into the workpiece and improves hole accuracy, while also staying manageable to re-sharpen for repeated use.
- Steam-tempered (steam oxide) finish reduces chip sticking at the cutting edge, helping maintain clean starts and extending tool life in repetitive drilling tasks.
- Long length series is optimized for deeper holes and real-world reach in confined spaces, maintaining rigidity and precision even when access is limited.
- Premium HSS material handles a variety of metals—from steel and stainless steel to aluminum—without compromising tip integrity, making it a versatile addition to any workshop.
- Versatile for handheld and machine applications, giving you the flexibility to tackle projects on a workbench or in automated setups with consistent results.
Ideal for machinists, maintenance technicians, and fabricators who regularly drill thicker workpieces or components requiring extended reach, the A110 long-series drill is well-suited for both prototyping and production environments. In steel, aluminum or stainless steel, this drill delivers steady feeds, controlled chip formation, and reliable hole quality, helping you minimize run-out and rework.
