Dormer Pramet A976 5.90 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Dormer Pramet A976 5.90 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1 is engineered for professionals who demand precision, reach, and reliability in deep-hole applications. This drill blends advanced geometry with premium materials to deliver consistent performance across a range of metals and demanding layouts.

Core advantages that drive real-world results

• 130° point for self-centering and reduced thrust
• Bright finish minimizes sticking and built-up edge on the cutting edge
• Parabolic flute design optimized for chip evacuation in deep holes, enabling a single-pass drill through long depths
• Premium HSS-E material enhanced wear resistance makes it suitable for steel, aluminum, and stainless steel
• Extra-long length, straight shank designed to reach deep pockets, cavities, and hard-to-access work areas
• DIN 1869 compliance ensures compatibility with standard drilling setups and tooling systems

Who benefits most

Ideal for machining professionals who routinely drill deep holes in automotive frames, machining centers, mold making, aerospace components, and hydraulic assemblies. The extra reach combined with stable centering reduces rework and improves hole accuracy in challenging workpieces where space is limited.

Use cases and practical applications

• Deep hole drilling in steel and stainless steel thank to the parabolic flute that efficiently channels chips away from the cutting edge
• Probing and boring operations where access is restricted or space is tight, thanks to the extra-long series
• Pre-machined or near-net shapes where precise centering minimizes walk and ensures clean through-holes
• Aluminum and non-ferrous work where the bright finish helps prevent material sticking and reduces galling

How this drill stands apart from alternatives

While many drills struggle with long-geometry holes or require multiple passes, the A976 combines a 130° point, a parabolic flute profile, and an extra-long straight shank to deliver accurate, deep-hole results in a single pass. The HSS-E construction adds durability for repeated use across diverse materials, reducing tooling downtime and boosting overall productivity in busy workshops.

Tips for optimal performance

• Use appropriate cutting fluid or coolant to manage heat during deep-hole drilling
• Start with a light feed to establish the 130° point and reduce walk, then maintain steady advancement
• Respect material hardness: for stainless steel, consider slower feeds and controlled speeds to maximize edge life
• Ensure proper workholding and steady clamping to prevent deflection on long reach operations
• Inspect the drill after use for edge wear and chip buildup, and store in a dry, organized rack to prevent corrosion
