Dormer Pramet A952 28.00 mm HSS HIGH PERF MULT-APP MORSE TAPER SHANK EXTRA LONG SERIES DRILL DIN 1870 (2)

The Dormer Pramet A952 28.00 mm HSS High Performance Multi-App Morse Taper Shank Extra Long Series Drill, DIN 1870, is built to redefine deep-hole metalworking. This precision drill brings together long-reach capability with rugged reliability, making it a go-to choice for demanding installation, maintenance, and fabrication tasks.

• 130-degree point for confident self-centering and a smoother start, reducing the push force you feel at the drill tip and helping you maintain pierce accuracy from the first cut.
• Bright finish minimizes material adhesion on the cutting edge, simplifying chip evacuation and reducing workpiece drag during extended drilling passes.
• Parabolic flute design engineered for extra-deep holes, enabling efficient chip removal and stable cutting in a single pass—ideal when reach matters as much as diameter.
• Premium HSS material delivers dependable performance across a range of metals, including steel, aluminum, and stainless steel, making this drill a true multi-material workhorse.
• Extra-long series with Morse taper shank provides extended reach in machine tools while maintaining rigid alignment in the spindle, so you can drill deep pockets, step through housings, or pierce thick workpieces without repositioning.
• DIN 1870 compatibility ensures reliable fit in compatible drill chucks and CNC/spindle setups, supporting consistent hole quality in automation environments.

Why this drill stands out in a crowded field is its combination of reach, precision, and material versatility. The extra-long body paired with a robust HSS core minimizes deflection and chatter on deep holes, while the self-centering point and efficient flute geometry keep hole geometry clean and true, even when drilling through challenging alloys or seasoned metals.

This drill is ideal for workshops, job shops, and production environments where every deep-hole operation must be accurate, repeatable, and capable of penetrating multiple materials without changing tools. It’s especially well-suited for automotive and aerospace fixtures, engine blocks, hydraulic and pneumatic manifolds, and general fabrication tasks that demand long, reliable drilling performance.

Practical tips for best results: - Use steady, controlled feeds to take advantage of the parabolic flute’s chip evacuation. - Apply a compatible cutting fluid or coolant when drilling stainless steel or alloys prone to work-hardening to extend tool life. - Ensure the drill is properly seated in the spindle and the Morse taper is fully seated to minimize runout on deep holes. - Deburr and chamfer hole entrances after drilling to achieve clean, functional tolerances in assemblies.
