Meet the Dormer Pramet A976 6.10 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Drill, a purpose-built solution for deep-hole work across a range of materials. With a precise 6.10 mm diameter and DIN 1869 / 1 designation, this drill is engineered for dependable accuracy in demanding environments where reach and consistency matter.

• 130-degree point for self-centering accuracy and reduced push force, helping you start holes cleanly and maintain alignment even in hard-to-reach spots.
• Bright finish minimizes sticking and built-up material on the cutting edge, promoting smoother starts and longer edge life.
• Special parabolic flute design optimizes chip evacuation and stability when drilling very deep holes in a single pass, reducing chatter and improving hole quality.
• Premium HSS-E material delivers toughness and heat resistance, suitable for drilling steel, aluminum, and stainless steel without frequent tool changes.
• Extra long length series provides the extended reach needed for deep cavities, internal drilling, and applications where standard-length bits just won’t reach.
• Straight shank ensures compatibility with a wide range of chucks and holders, delivering reliable grip and precise retraction.
• DIN 1869 / 1 compliance confirms dimensional standards and reliability for machining setups that rely on standardized tooling.

Typical use scenarios include drilling deep holes in structural steel components, automotive housings, hydraulic and pneumatic manifolds, and aerospace-grade assemblies where long reach and precise hole geometry are critical. This drill shines when you need one tool to handle multi-material workpieces without changing bits mid-project, reducing downtime and tool inventory.

How this drill improves outcomes:

• Cleaner starts and reduced exit wandering thanks to the 130-degree point.
• Lower risk of workpiece sticking and built-up edge due to the bright finish.
• Consistent deep-hole holes with less chatter because of the parabolic flute design.
• Versatility across common metals—from steel to stainless—without swapping tooling.
• Extended reach that enables access to cavities, blind holes, and long internal channels.

Practical tips for best results: use appropriate cutting fluid or dry machining with light lubrication, select spindle speeds and feeds suited to the material, and maintain steady alignment to maximize the benefits of the extra-long reach and the drill’s self-centering geometry. For DIN-standard setups, pairing this drill with compatible holders and an appropriately designed drilling cycle will yield consistent hole quality and extended tool life.
