Description
Dormer Pramet A110 9.70 mm HSS ST Straight Shank Long Series Drill DIN 340 is built for serious metalworking tasks that demand depth, precision, and reliability. This long-series drill combines a robust HSS core with a straight shank for broad compatibility in handheld drills and machine tools, making it a go-to choice for fabricators, maintenance technicians, and dedicated DIY enthusiasts tackling deep-hole projects.
The 118-degree conventional point delivers a strong, self-centering entry that’s easy to re-grind when you need to restore a fresh cutting edge. Paired with a steam oxide finish, this drill minimizes chip adhesion and gumming at the cutting edge, helping you achieve cleaner holes and longer tool life in demanding materials.
Key features tailored for versatility and performance:
- Diameter: 9.70 mm for precise, consistent bore sizes in a range of applications.
- Long length series: Optimized for drilling deeper holes or accessing recessed areas where standard-length bits fall short.
- Premium HSS material: Suitable for drilling steel, aluminium, and stainless steel with durable edge retention.
- DIN 340 compliant: Ensures reliable fit and interchangeability with standard chucks and holders.
- Straight shank: Easy to clamp securely in both manual and automated setups, reducing runout and improving accuracy.
- Versatile in practice: A single drill for hand-held drilling, drill presses, and other machine tools across a range of fabrication tasks.
Who benefits most: professionals performing deep-hole drilling in metal components, engineers fabricating enclosures or frames, automotive and aerospace maintenance crews, and serious hobbyists who require consistent performance from a single, reliable drill bit in steel, aluminum, and stainless steel.
Practical guidance for best results
To maximize life and performance of the A110 drill, pair it with appropriate feeds and speeds for the material you’re drilling, use a steady cutting action, and apply a suitable cutting fluid or coolant to reduce heat buildup. For deeper holes, consider securing the workpiece and using a drill guide or depth stop to maintain straightness and prevent wandering. Always inspect the edge after each re-grind and refresh as needed to maintain the clean entry and true bore you rely on.
