Dormer Pramet A952 15.00 mm HSS HIGH PERF MULT-APP MORSE TAPER SHANK EXTRA LONG SERIES DRILL DIN 1870 (2)

The A95215.0 is an extra-long HSS drill engineered for demanding deep-hole applications in a variety of materials. With a 15 mm cutting diameter and a Morse taper shank, this DIN 1870 (2) drill is built to fit directly into machine spindles while delivering consistent, accurate holes from the first entry to the final exit.

Key features that matter in real-world drilling

• 130° point for precise start – the acute tip promotes self-centering and reduces the initial push force, helping you avoid wandering at the workpiece edge and maintain true hole alignment.
• Bright finish – the clean, polished edge minimizes material adhesion to the cutting edge, reducing built-up edge and improving chip evacuation for smoother, cleaner holes.
• Parabolic flute design with parabolic web – optimized for deep-hole drilling, letting you reach substantial depths in a single pass without pecking, especially in steel.
• Premium HSS (High-Speed Steel) – versatile performance across common metals, including steel, aluminum, and stainless steel, making it a reliable choice for mixed-material jobs.
• Extra-long length, DIN 1870 (2) Morse taper shank – designed for machine ops where the drill is held directly in the spindle, providing stability and consistent concentricity for long-hole work.
• Depth capability – optimized for drilling up to 20×D without pecking in steel, enabling deep-hole projects with fewer tool changes and tighter process control.
• No coolant channel – a straightforward through-diameter design that suits dry or flood coolant setups as your machining setup requires.

Why this drill stands apart for multi-application drilling – The A952 series is purpose-built for versatility. When you’re switching between steel, aluminum, and stainless workpieces, you need a single drill that can handle the job with minimal setup changes. The 130° point reduces centering effort, while the parabolic core and flute geometry minimize chatter and deflection during long-hole passes. This combination translates to tighter hole tolerances, smoother finishes, and fewer interruptions in production runs.

Who benefits most – machinists and operators who routinely perform long-hole drilling in DIN 1870 compliant toolholders, fabricators building automotive housings, gear blanks, or structural components, and shops handling mixed-material prototypes where tool inventory efficiency matters.

Practical usage tips

• Match spindle speed and feed rate to the 15 mm diameter and 20×D depth target to maintain a stable cut and prolong insert edge life.
• Secure the workpiece firmly and use light, consistent feed to exploit the drill’s self-centering capability and reduce runout.
• Monitor chip removal to prevent recutting; a steady flow of chips improves hole quality and surface finish.
• Since this drill has no through-coolant channel, plan cooling strategy accordingly—dry drilling or flood cooling as your setup requires.

Designed for reliable, high-performance drilling in industrial settings, the Dormer Pramet A95215.0 delivers depth, precision, and versatility in a single, robust tool. Its DIN 1870 (2) Morse taper shank and extra-long geometry ensure it remains the workhorse choice for machines that demand consistent, deep-hole capability from a single tool.
