The Dormer Pramet A952 14.00 mm HSS High-Performance Multi-Application Morse Taper Shank Extra Long Series Drill (DIN 1870) is built to conquer demanding deep-hole tasks with precision and reliability. Designed for modern machining where rigidity and consistent hole quality matter, this drill delivers a dependable, long-lasting performance in a compact, single-pass design.

• 130-degree point for self-centering—reduces workpiece deflection and lowers push force, helping you start holes accurately and maintain alignment under challenging feeds.
• Bright finish—minimizes material sticking to the cutting edge, improving chip evacuation and reducing built-up edge during prolonged drilling sessions.
• Parabolic flute design—optimized to penetrate deeply with minimal clogging, enabling extra deep holes in a single pass and improving hole concentricity.
• Premium HSS material—engineered for versatile performance across common drillable materials including steel, aluminum, and stainless steel, delivering dependable tool life in mixed-material environments.
• Morse taper shank—provides robust, central rigidity in the spindle for high-torque drilling, ideal for machine work where the drill is held directly in the spindle.
• Extra-long series—designed to reach deeper holes without multiple setups, boosting productivity in fabrication, automotive, and aerospace applications.

Typical use scenarios include through-holes and blind holes in steel or alloy components, aerospace fixtures, automotive chassis work, and general fabrication where deep hole quality and repeatability are critical. The A952’s 14.00 mm diameter is a precise choice for exacting holes that demand reliable centering, clean exits, and consistent diameter control across long depths.

Compared with standard-length or shorter drills, this tool’s extended reach and rigid Morse shank minimize deflection and chatter, helping you maintain straight, true holes even when workpieces are tough or geometry is complex. Its design supports high-speed drilling with minimal coolant interruption, enabling efficient production runs without frequent tool changes.

Tips for optimal performance:

• Use appropriate spindle speeds and feeds for the material being drilled to maximize tool life and hole quality.
• Apply a light cutting fluid or coolant to reduce heat and extend edge life, especially on stainless steel and alloys.
• Ensure proper workpiece clamping to prevent vibration, which can compromise hole straightness on deep drilling tasks.
• Inspect the flute condition after heavy use; a sharp edge and clean flutes are essential for consistent hole diameters.
