Dormer Pramet A977 1/16 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (2) DRILL DIN 1869 / 2

Meet the Dormer Pramet A977 1/16 Inch HSS-E High Performance Multi-Application Straight Shank Extra Long Drill (DIN 1869 / 2) — a precision micro-drill engineered for deep-hole precision across a range of metals. With its 1/16" diameter, this tool delivers focused performance in tight tolerances and hard-to-reach spots, making it a go-to for detailed metalworking tasks.

Why this drill stands out

• 130-degree point for self-centering starts and reduced push force, helping you initiate holes with minimal wandering and smoother entry.
• Bright finish minimizes material sticking to the cutting edge, enhancing chip evacuation and reducing built-up edge during drilling.
• Parabolic flute design tailored for extra-deep hole drilling in a single pass, keeping chips moving efficiently and maintaining hole quality even at great depths.
• Premium HSS-E material delivers robust performance across materials — from steel and stainless steel to aluminum — while offering extended tool life and consistent hole quality.
• Extra long length profile provides the reach needed for deep cavities, long blind holes, and applications where standard drills can’t reach.
• Straight shank design ensures secure clamping in standard drill chucks and holders, delivering reliable runout control for precision holes.

This drill isn’t just about cutting metal—it’s about dependable accuracy in demanding environments. The A977’s geometry and build are optimized for repeatable results, whether you’re producing a series of identical small-diameter holes or tackling intricate assemblies where depth and alignment matter.

Ideal applications and use cases

Perfect for machine shops, fabrication floors, and repair workshops that routinely drill deep holes or work in confined spaces. Ideal scenarios include automotive component fabrication, precision hardware, aerospace fixtures, and any project requiring accurate 1/16" holes with exceptional depth capability. The combination of a fine diameter, long reach, and deep-hole drilling capability makes it a versatile choice for multi-pass or single-pass drilling strategies.

Practical tips for best results:

• Use light, steady feeds and avoid aggressive plunging to preserve tool life and hole quality, especially in hard metals.
• Apply appropriate cutting fluid or coolant to reduce heat buildup when drilling deep holes.
• Take small pecking passes if chip evacuation becomes difficult, then resume steady drilling once the flute clears.
• Pair with compatible straight-shank holders and ensure proper alignment to maintain hole straightness through the entire depth.

Compliance and compatibility: DIN 1869 / 2 standard, combined with HSS-E substrate, ensures predictable interchange with common drill chucks and adapters. Store in a dry environment and protect the cutting edge to extend tool life between jobs.
