Dormer Pramet A125 1.50 mm x 160 mm HSS ST STRAIGHT SHANK EXTRA LONG SERIES DRILL BS 328

Meet the Dormer Pramet A125 1.50 mm x 160 mm HSS straight shank extra long drill BS 328—the drill bit designed for serious deep-hole work in metal. With a precisely engineered 118-degree conventional point, this drill starts cleanly, centers quickly, and stays true through the cut, making it a reliable choice for demanding fabrication tasks.

Exceptional performance where depth meets precision

• 118-degree conventional point — a robust tip that’s easy to re-grind, delivering dependable starts and reducing wandering when you begin a hole.
• Bright finish — minimizes material sticking to the cutting edge, promoting smoother chip flow and extended edge life in tough metals.
• Extra long length (160 mm) — specially suited for drilling very deep holes or reaching into recessed workpieces where standard drills can’t reach.
• Premium HSS material — high-speed steel built for durability across a range of metals, including steel, aluminium, and stainless steel, while maintaining sharpness under demanding workloads.
• Straight shank design — ensures reliable clamping and compatibility with most drill chucks and machine setups, delivering consistent performance across different machines.
• BS 328 specification — aligned with industry standards for sizing and geometry, providing predictable results and interchangeability with other tools in the same class.

Why this drill stands out

When you’re drilling deep into metal, accuracy and repeatability matter. The A125’s combination of a strong point, long reach, and a finish that keeps the cutting edge clean translates into fewer re-drills, less chatter, and smoother hole quality. It’s a versatile choice for workshops that tackle automotive components, fabrication projects, and maintenance tasks where access is limited and precision is non-negotiable.

Ideal use scenarios

Use this drill to create deep, clean holes in steel brackets, machine frames, and profiles where a standard-length drill would fall short. It performs reliably on a variety of metals when paired with appropriate feeds and speeds, and its regrindable tip helps extend service life between replacements, keeping downtime to a minimum.

For best results, pair with a capable drill press or machine spindle, and maintain consistent cutting conditions to preserve the 118-degree point geometry and edge integrity over multiple holes.
