The Dormer Pramet A125 13.00 mm x 400 mm HSS straight shank extra long drill is engineered for serious deep-hole work. With a robust 118° conventional point and a long reach, this BS 328-compliant drill powers through metals while maintaining true alignment and precision, even in tight or hard-to-reach spots.

• 118° conventional point. A strong, easy-to-regrind cutting tip that promotes reliable starts and consistent hole dimensions, reducing walk and chatter during initial entry.
• Steam tempered (steam oxide) finish. The specialized finish minimizes workpiece material sticking to the cutting edge and improves chip flow, helping maintain a clean cut over long production runs.
• Extra-long length (400 mm overall). Designed for drilling very deep holes or applications where extended reach is essential, while preserving rigidity along the flute length. The flute length is typically around 300 mm, providing substantial cutting depth.
• Premium HSS material. High-speed steel offers versatile performance across a wide range of workpiece materials, including steel, aluminum, and stainless steel, making this drill a dependable choice in mixed-material setups.
• BS 328 standard, 10xD drilling capability. This extra-long drill is specified for deep-hole work up to 10 times the diameter in a single pass in steel, a practical feature for production environments where efficiency matters.
• Versatile, machine-ready performance. Compatible with a range of machining centers and drill presses, the A125 series is well-suited for workshops that demand reliable, repeatable deep-hole drilling without changing tools frequently.

Ideal for professional machinists, fabrication shops, and maintenance engineers tackling deep-hole projects, the Dormer Pramet A125 drill delivers dependable entry, long life, and consistent hole quality. When you need reach without sacrificing edge life or material versatility, this 13.0 mm x 400 mm drill is a proven choice that aligns with BS 328 specifications and real-world drilling demands.
