Meet the Dormer Pramet A125 6.00 mm x 200 mm HSS straight shank drill — a purpose-built tool designed for dependable deep-hole drilling across a range of materials. This extra-long series is crafted to reach those hard-to-access spaces without compromising precision or edge durability, making it a trusted choice for fabrication, maintenance, and engineering workshops.

Key features that matter on the job

• 118° conventional point — delivers a strong, self-centering start that’s easy to re-sharpen, helping you maintain accuracy even after repeated sharpening.
• Steam oxide finish — reduces workpiece material from sticking to the cutting edge and enhances chip flow, keeping cutting action smooth and steady.
• Extra-long length (200 mm) — designed for drilling very deep holes and for applications where extended reach is required, minimizing the need for multiple tools or setups.
• Premium HSS material — versatile enough for drilling steel, aluminum, and stainless steel, delivering dependable performance across common workshop materials.
• Straight shank — broad compatibility with a wide range of drilling machines and chucks, enabling straightforward integration into existing toolkits.

Why this drill stands out for deep-hole tasks

When deep, precise holes are essential, the A125’s geometry and robust construction minimize wandering and chatter while maximizing control. The extended flute length and strong point reduce breakthrough force, helping you maintain clean hole finishes in challenging materials. This isn’t a one-trick tool: it excels in everyday deep-hole work and specialty projects alike, from lifting eyelets in structural work to precision bores in automotive components.

Use cases and practical tips

• Ideal for deep holes: reach into recesses or recessed channels where standard bits can’t reach, such as long through-holes in steel brackets or aluminum housings.
• Material versatility: trusted for drilling steel, aluminum, and stainless steel with dependable edge retention and efficient chip evacuation.
• Machining approach: use proper work-hold to prevent movement, apply a compatible cutting fluid or lubricant, and employ a cautious pecking technique to clear chips and prevent heat buildup.
• Sharpening and care: the 118° point is easy to re-sharpen; keep the edge clean and true to preserve performance across multiple uses.
