Dormer Pramet A125 11/64 Inch x 160 mm HSS ST STRAIGHT SHANK EXTRA LONG SERIES DRILL BS 328

Meet the Dormer Pramet A125 11/64 Inch x 160 mm HSS ST Straight Shank Extra Long Series Drill BS 328—built for deep, precise holes in a variety of metals. With an 118-degree conventional point, this bit starts cleanly and resists wandering, delivering accurate hole location right from the first cut.

• Steam oxide finish helps prevent workpiece material from sticking to the cutting edge, reducing chip welding and extending tool life in tough metals.
• Extra-long length (160 mm) provides extended reach for drilling deep holes, through thick workpieces, or in assemblies where access is limited.
• Premium HSS material handles a broad range of metals—from steel and aluminium to stainless steel—with dependable performance and durability.
• Straight shank offers universal compatibility with most drill chucks, collets, and machines—from drill presses to CNC mills, ensuring stable, accurate cuts.
• BS 328 compliance guarantees standard dimensions and quality you can rely on in professional shop environments.

This drill is ideal for fabricators, machinists, and engineers tackling deep-hole projects: automotive components, hydraulic blocks, frame assemblies, or any application where you need to reach into the heart of the workpiece without repositioning the setup. Use with appropriate cutting fluid, start with a light feed to establish a true start, and gradually increase pressure as the flute clears chips. Regrindability of the point helps you maintain repeatable performance over many holes.

In practice, the A125 Extra Long Drill reduces tool changes and increases productivity by letting you complete deeper holes in a single setup. It’s a versatile, durable choice for metalworking tasks that demand long reach, precise starts, and reliable edge quality.
