Dormer Pramet A977 1.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (2) DRILL DIN 1869 / 2

Discover the Dormer Pramet A977 1.50 mm HSS‑E High Performance Multi‑App Straight Shank Extra Long Drill (DIN 1869/2) — a compact, precision micro‑drill delivered as a convenient two‑bit pack. Crafted for dependable micro‑hole drilling across a range of metals, it’s the go‑to choice when depth and accuracy matter in tight spaces.

• 130° self‑centering point: begins cutting precisely where you aim, minimizes drift, and reduces push force for cleaner starts in confined pockets.
• Bright finish: a polished cutting edge that resists material sticking, supporting smoother chip flow and cleaner holes.
• Parabolic flute design: optimized for drilling extra‑deep holes in a single pass, promoting efficient chip evacuation and reduced clogging.
• Premium HSS‑E alloy: cobalt‑enhanced steel delivering improved hardness and heat resistance, suitable for steels, stainless steels, and aluminium.
• Extra‑long length: extended reach for deep holes, thick components, or hard‑to‑access areas while maintaining rigidity.
• Straight shank, DIN 1869/2: compatible with common chucks and collets; precise 1.50 mm diameter ensures controlled, repeatable holes.
• Pack of two: ready for multi‑hole projects or backup tools on busy shop floors.

Who should reach for the A977 1.50 mm drill? It’s ideal for micro‑machining tasks in electronics enclosures, precision mechanical assemblies, and tight‑tolerance fixtures where deep, accurately placed holes are required without frequentTool changes. Its all‑purpose performance makes it a reliable choice for shops that regularly switch between steel, stainless steel, and aluminum workpieces.

Practical tips for best results:

• Use appropriate cutting fluid or coolant to manage heat when drilling harder materials.
• Begin at a conservative speed and feed, then gradually increase as the hole depth and material allow.
• Secure the workpiece firmly to minimize vibration and ensure straight, true holes.
• For very deep holes, maintain steady lubrication and avoid aggressive plunging to prevent edge chipping.
• Inspect the hole after drilling for burrs and deburr as needed to ensure proper fitment of subsequent components.
