Dormer Pramet A110 7.20 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 7.20 mm HSS ST Straight Shank Long Series Drill (DIN 340) — a purpose-built tool for deep-hole metalworking that combines a robust tip with extended reach for demanding applications.

Its 118° conventional point delivers a strong, self-centering start and is designed to be easily re-ground, so you can extend the life of the tool without sacrificing precision.

The steam-oxide finish reduces material sticking to the cutting edge, promoting cleaner holes and smoother chip evacuation on every pass.

The long-length series provides real advantages when drilling deep holes or reaching into recessed workpieces, enabling you to complete jobs in fixtures or with handheld setups where standard-length drills fall short.

Made from premium high-speed steel (HSS ST) for reliable performance across a range of metals — from structural steel and aluminium to stainless steel — this drill handles a variety of materials in fabrication, maintenance, and manufacturing environments.

Versatility is at the core of the Dormer Pramet A110. Whether you’re pairing it with a drill press, milling machine, or a handheld drill, this straight-shank drill maintains concentric accuracy and consistent hole quality. The DIN 340 designation ensures compatibility with common collets and chucks used in professional workshop settings.

• Diameter: 7.20 mm
• Point geometry: 118° conventional point, self-centering and re-grindable
• Finish: Steam oxide to minimize built-up edge
• Length: Long series — optimized for deep-hole drilling and extended reach
• Material: Premium HSS (high-speed steel)
• Applications: Steel, aluminium, stainless steel; suitable for hand-held and machine operations

Practical tips for best results: start with a clean pilot hole, use appropriate lubrication or cutting fluid on steel, and maintain steady feeds to preserve the tip. If you need to extend tool life, rely on the re-grindable point to restore accuracy rather than swapping to a new drill whenever possible.

Designed for professionals who demand precision and depth in every hole, the Dormer Pramet A110 7.20 mm HSS Straight Shank Long Series Drill helps you finish projects faster with reliable, repeatable results. Add it to your toolkit and experience improved hole quality, longer tool life, and the flexibility to tackle challenging depths with confidence.
