The Dormer Pramet A952 21.00 mm High-Performance HSS drill is engineered for serious metalworking demands. Built around a premium HSS core and a purposefully long design, this drill delivers dependable accuracy, reach, and versatility in a single tool. Designed for machines that hold the drill directly in the spindle, it combines precision with durability for everyday workshop performance and demanding production tasks.

• 130-degree point for excellent self-centering and a lighter push force, helping you start holes cleanly and reduce breakage during entry.
• Bright finish minimizes material sticking to the cutting edge, promoting smoother chip flow and easier finishing passes.
• Special parabolic flute design tailored for deep-hole drilling, allowing extra-long holes to be produced in a single pass with consistent accuracy.
• Premium HSS material capable of drilling a broad range of metals, including steel, aluminium, and stainless steel, without frequent tool changes.
• Extra-long series with Morse taper shank for extended reach and secure retention in compatible spindles (DIN 1870 standard), enabling access to challenging workpieces and deep cavities.
• Multi-application versatility ideal for machine tools and setups where the drill is mounted directly in the spindle, reducing grip issues and improving runout stability.

Who benefits most from the Dormer Pramet A952? machinists and fabricators tackling deep-hole drilling, jobs in tight spaces, or projects requiring repeated, reliable performance across materials. It’s a practical choice for tool inventories that demand one drill to handle steel, aluminum, and stainless steel with dependable wear resistance and precise hole geometry. Whether you’re drilling through thicker sections, creating clean clearance holes, or preparing pilot holes for threading operations, this drill offers a straightforward, durable solution.

Practical tips for optimal results:

• Maintain appropriate cutting speeds and feeds for each material to extend tool life and improve hole quality.
• Use a suitable coolant or lubrication to manage heat during longer drilling passes.
• For very deep holes, advance gradually with periodic pecking to clear chips and prevent clogging.
• Ensure the spindle and drill mate securely to maximize accuracy and reduce runout, especially with the Morse taper shank.
