Dormer Pramet A125 1.50 mm x 125 mm HSS ST STRAIGHT SHANK EXTRA LONG SERIES DRILL BS 328

Meet the Dormer Pramet A125 1.50 mm x 125 mm HSS ST Straight Shank Extra Long Series Drill BS 328 — a precision drill built for deep-hole tasks where reach and reliability matter as much as edge quality. This isn’t just another twist drill; it’s a purpose-built tool designed to deliver consistent performance in demanding metalworking environments.

• 118-degree conventional point: a robust, easy-to-reground tip that starts cleanly and resists wandering, even when drilling through tougher materials.
• Bright finish: minimizes workpiece material sticking to the cutting edge, promoting smoother chip flow and steadier hole quality.
• Extra long length: tailored for drilling very deep holes or accessing recessed features, giving you extended reach without sacrificing rigidity.
• Premium HSS material: versatile across a range of materials, including steel, aluminium, and stainless steel, making it a reliable choice for mixed-material environments.
• Straight shank: designed for secure clamping in common drill chucks and CNC interfaces, delivering stable cutting performance on long-hole operations.
• BS 328 specification: ensures consistent geometry and interchangeability with standard tooling, reducing setup time and ensuring predictable results.

Ideal uses: drilling deep holes in steel and non-ferrous metals where access is restricted, performing through-hole and blind-hole operations, and tackling applications that demand reliable performance from an extra-long drill without complex tooling changes.

Why this matters: when you’re shaping components with tight tolerances or machining assemblies with internal features, hole diameter control and edge integrity are critical. The A125’s combination of a robust tip, bright finish for efficient chip evacuation, and extended reach translates into cleaner holes, fewer re-drills, and improved productivity across your workshop or production line.
