Introducing the Dormer Pramet A952 24.00 mm HSS High-Performance Multi-Application Morse Taper Shank Extra Long Series Drill (DIN 1870). Built for precision, depth, and reliability, this drill is engineered to tackle demanding metalworking tasks with consistent results—from clean centering to deep-hole performance.

Key features that matter in real-world drilling

• 130-degree point for self-centering and reduced push force, helping you start holes accurately without wandering off center.
• Bright finish minimizes workpiece material from sticking to the cutting edge, promoting smoother starts and cleaner holes.
• Parabolic flute design optimized for deep-hole drilling, enabling deeper holes in a single pass with efficient chip evacuation.
• Premium HSS material delivers solid performance across a range of metals, including steel, aluminum, and stainless steel, with good wear resistance and long tool life.
• Morse taper shank for direct, reliable mounting in machine spindles, ensuring concentricity and stability during heavy cutting
• Extra-long series extends reach for deep or through-hole drilling where standard length tools fall short, reducing tool changes and setup time.
• DIN 1870 compatibility ensures consistent fit with compatible chucks and spindles, simplifying replacement and interchangeability on standard tooling setups.

Why this drill is the right choice for multi-material work

The Dormer Pramet A952 is purpose-built for environments where you switch between different materials or need one drill that can handle multiple applications without changing tools. The combination of the 130-degree point and the parabolic flute geometry improves drilling efficiency, minimizes deflection, and reduces heat buildup—extending insert life and maintaining hole quality across workpieces like thick steel plates, aluminum sheets, and stainless components.

Ideal use cases and who benefits most

• Machine shops and job shops performing mixed-material drilling, from structural steel to aluminum fixtures and stainless assemblies.
• Fabrication and automotive shops that require deep-hole capability in a single setup to shorten cycle times.
• Educational or prototyping environments where dependable performance and repeatable centering matter for quick turnaround projects.

Practical tips for optimal performance

• Use appropriate spindle speeds and feeds tailored to the material being drilled; start with a conservative feed and increase gradually to balance hole quality and tool life.
• Maintain an ample lubrication or cutting fluid supply to reduce heat and extend life when drilling deep holes.
• Ensure the Morse taper shank seats fully in the spindle bore to preserve concentricity and reduce runout during operation.
• For very deep holes, consider peck drilling techniques in combination with the parabolic flute design to promote steady chip evacuation.

With the Dormer Pramet A952, you’re choosing a dependable, all-in-one drilling solution that combines precision centering, deep-hole capability, and broad material compatibility in a single, robust tool. It’s the smart choice for professionals who demand consistency, efficiency, and long tool life in every hole.
