Description
The Dormer Pramet A321 13.00 mm HSS Tri-Flat Shank Intermediate Length Mechanics Drill is a versatile high-speed steel drill designed for strength, durability, and precision. The tri-flat shank provides a secure grip in drill chucks, helping minimize slipping during operation.
With an intermediate length, it strikes a balance between rigidity and reach, making it ideal for general-purpose drilling across steel and non-ferrous metals. The polished finish reduces friction and improves chip evacuation, helping you achieve clean, accurate holes with less effort.
- Tri-Flat Shank for Secure Chuck Grip: Keeps the drill firmly engaged in the chuck, reducing slippage and improving hole alignment during demanding drilling tasks.
- Intermediate Length for Rigidity and Reach: Offers the right mix of stiffness and access, enabling reliable performance in tighter workspaces and deeper holes without deflection.
- Polished Finish and HSS Material: Delivers smoother cutting action, better chip evacuation, and compatibility with steels and non-ferrous metals for versatile use.
Whether you’re an engineer, machinist, or hobbyist, this drill helps you finish jobs faster with consistent hole quality and fewer tool changes. The robust HSS composition and secure shank design translate to reliable performance across a range of materials, reducing downtime, improving workflow, and delivering repeatable results you can trust on every project.
