Dormer Pramet A125 4.00 mm x 200 mm HSS ST STRAIGHT SHANK EXTRA LONG SERIES DRILL BS 328

Introducing the Dormer Pramet A125 4.00 mm x 200 mm HSS straight shank drill—the trusted deep-hole partner for professional workshops and production floors. Built for sustained performance, this extra-long drill is engineered to reach into tight recesses and drill long through-holes with precision and reliability.

• 118-degree conventional point — emits a strong initial bite for clean starts and predictable re-grinding, minimizing wandering and improving hole accuracy from the first cut.
• Steam oxide finish — reduces material adhesion on the cutting edge and flutes, promoting smoother chip evacuation and extending tool life during demanding drilling cycles.
• Extra long length (200 mm) — specifically designed for drilling very deep holes and accessing hard-to-reach areas, while maintaining control and rigidity thanks to a robust straight shank.
• Premium HSS material — versatile enough to drill a wide range of metals, including steel, aluminium, and stainless steel, making it a practical choice for mixed-material applications.
• Straight shank design — ensures compatibility with common drill chucks and collets, delivering stable, straight holes even in challenging setups.
• BS 328 compatibility — built to meet standard boring and sizing conventions, enabling consistent interchangeability with compatible machinery and accessories.

Ideal for workshops and fabrication shops tackling deep-hole tasks, this drill is particularly effective in automotive components, machinery housings, and thick workpieces where reach matters as much as precision. The A125 series combines durability with practical convenience, reducing the need for frequent tool changes in long-hole operations.

Usage tips for best results:

• Clamp the workpiece securely and use a rigid drilling setup to prevent deflection during deep-hole cuts.
• Apply appropriate cutting fluid to minimize heat buildup and extend tool life, especially on harder materials like stainless steel.
• Start with a conservative speed and feed, then gradually increase as the drill tracks true and heat remains controlled.
• Maintain a steady, straight approach to preserve hole geometry and avoid wander in deep pockets.
