Meet the Dormer Pramet A125 8.00 mm x 250 mm HSS straight shank drill—an indispensable tool for metalworkers who demand depth, precision, and lasting performance in a single bit. Designed to handle demanding deep-hole work without sacrificing hole quality, this drill is built to keep pace with professional fabrication and maintenance environments.

• 118-degree conventional point delivers confident starts and precise hole entry, reducing wander and improving straightness from the first cut. The point is easy to re-grind, helping you extend tool life without sacrificing accuracy.
• Steam oxide finish minimizes friction and prevents workpiece material from sticking to the cutting edge, producing cleaner holes and smoother chip evacuation—especially in harder alloys.
• Extra long length (250 mm) is purpose-built for deep drilling tasks, thick sections, or constrained workpieces where standard-length drills can’t reach. When reach matters, this bit shines.
• Premium HSS material offers generous toughness and heat resistance, enabling reliable drilling across a variety of metals—including steel, aluminum, and stainless steel—without frequent tool changes.
• Straight shank ensures broad compatibility with most chucks, drill presses, and CNC/milling machines, delivering stable feeding and minimal run-out for accurate, repeatable holes.
• BS 328 compliant designation signals dependable industrial usability and clear interchangeability with standard tooling setups.

This drill is ideal for shops and workshops that routinely tackle deep-hole tasks: thick plates, automotive frames, stainless components, or aluminum assemblies where hole depth and edge quality are paramount. Its robust core and long reach let you drill through challenging materials with confidence, reducing tooling downtime and boosting productivity on time-sensitive projects.

Why rely on the Dormer Pramet A125 in your tool kit? Because it combines a proven point geometry with a finish that keeps the edge clean, a length that conquers deep holes, and a versatile material construction that handles a broad spectrum of metals. If you’re drilling deep, precise holes in steel, aluminum, or stainless steel, this drill delivers dependable performance, fewer tool changes, and consistent hole quality from start to finish.
