Dormer Pramet A125 7/32 Inch x 200 mm HSS ST STRAIGHT SHANK EXTRA LONG SERIES DRILL BS 328

Dormer Pramet A125 7/32 Inch x 200 mm HSS Straight Shank Extra Long Drill

Engineered for serious drilling tasks, this HSS straight-shank drill from Dormer Pramet blends precision, durability, and reach. The A125 series is built to handle demanding holes with a clean, accurate start, even when you’re working deep in a workpiece or drilling across multiple stations.

• 118° conventional point for quick, predictable starts and reduced wandering. The sharp, robust tip maintains precision through continued use and is easy to re-grind when necessary, extending the life of the tool.
• Steam oxide finish reduces material adhesion at the cutting edge, helping chips evacuate smoothly and minimizing built-up edge during drilling.
• Extra long length (200 mm) in the Extra Long Series is designed for drilling very deep holes and for applications needing increased reach, such as through-thickness workpieces or multi-pass bores.
• Premium HSS (High-Speed Steel) construction delivers dependable performance across a range of materials, including steel, aluminium, and stainless steel, while offering good wear resistance and heat tolerance.
• Straight shank compatibility with standard drill chucks and machines, delivering consistent grip and easy setup in a wide variety of drilling setups.
• Versatile drilling solution suitable for metal fabrication, maintenance workshops, automotive machining, and general engineering tasks—where depth and precision matter most.

Use cases you’ll appreciate: tackling deep holes in plate and structural sections, drilling through long components, or reaching recessed cavities in assemblies where shorter bits won’t suffice. The A125 drill is ideal for shop floors and production lines that demand reliable performance from a single, durable tool.

Pro tips for best results

• Match the feed rate and spindle speed to the material: lighter materials like aluminium benefit from higher speeds with generous chip clearance; tougher steels require moderate speeds and steady pecking to prevent overheating.
• Use a light cutting fluid or oil to reduce friction, especially when drilling stainless steel or through-hardened materials.
• Peck drilling in deeper bores helps clear chips and maintains cutting efficiency; retract the drill periodically to wipe clean and re-lubricate the edge.
• Maintain the drill with regular inspection of the cutting edge; a sharp tip preserves accuracy and reduces required force during entry.

Whether you’re upgrading your metalworking toolkit or tackling a challenging deep-hole project, the Dormer Pramet A125 7/32" x 200 mm drilling solution delivers dependable performance, long life, and precise results—every time you pull the trigger.
