Dormer Pramet A976 3.20 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

The Dormer Pramet A976 3.20 mm HSS-E drill is built for deep-hole versatility across a range of materials. With an extra-long design and a straight shank, it reaches into tight spaces and thick sections where standard drills struggle, all while delivering precise, clean holes.

• 130° point for confident self-centering – The 130-degree point reduces the push force needed and helps the drill start accurately, minimizing wander and chatter during entry.
• Bright finish minimizes workpiece sticking – A smooth, bright coating keeps material from welding to the cutting edge, promoting consistent chip formation and easier part removal.
• Parabolic flute design for deep holes – The specially shaped parabolic flute provides efficient swarf evacuation, enabling drilling very deep holes in a single pass without frequent withdrawal.
• Premium HSS‑E (5% cobalt) for broad material compatibility – HSS‑E offers higher hardness and wear resistance, making the drill suitable for steel, aluminum, stainless steel, and other common workpiece materials.
• Extra-long length for increased reach – Designed for drilling very deep holes or applications where access is limited, this long-series drill extends your capabilities beyond standard drills.
• DIN 1869/1 standard and straight shank – Engineered to DIN 1869/1 specifications with a straight shank for compatibility with common drill chucks and holders.
• Drill depth capability – The A976 extra-long design is commonly used for high-depth drilling (approximately 15×D in many configurations), enabling long through-holes without constant restaging.

Ideal for machinists and workshops tackling deep-hole tasks in steel, aluminium, and stainless steel, the A976 combines a precise entry, efficient chip control, and extended reach to improve productivity on automotive, manufacturing, and maintenance projects. Its robust HSS‑E construction and parabolic flute system reduce the need for multiple pecks, saving time and friction while delivering consistent hole geometry.

Use cases include:

• Deep through-holes in steel components where access is limited
• Multi-material drilling in fabrication, automotive, and machinery assembly
• Pre-drilling for fasteners and alignment features in automotive and aerospace tooling

For best results, pair this drill with a rigid drilling setup, proper lubrication for steel workpieces, and appropriate feeds to leverage the parabolic flute’s swarf evacuation and the tool’s wear resistance.
