Dormer Pramet A940 4.80 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Dormer Pramet A940 4.80 mm HSS‑E High Performance Multi‑Application Straight Shank Long Series Drill (DIN/ANSI)

Designed for metalworking pros who demand consistency, the A940 drill balances versatility with precision. Built around premium HSS‑E material, this 4.80 mm drill excels across a wide range of ferrous and non‑ferrous metals, from structural steel to aluminum and stainless steel, delivering reliable holes that meet exacting specifications without constant tool changes.

• 130° point for self‑centering — minimizes wandering at entry and reduces push force, helping you start every hole squarely with less effort.
• Bright finish — lowers friction and prevents workpiece material from sticking to the cutting edge, promoting smoother cuts and cleaner holes.
• Parabolic flute design — engineered for deep drilling in a single pass, enabling you to reach true depth without the need for frequent retracts or pecking.
• Premium HSS‑E material — optimized for durability and toughness to handle a broad spectrum of materials, including steel, aluminum, and stainless steel.
• Straight shank long series — compatible with a wide range of drilling machines and collet systems, ideal for extended reach and stable cutting performance in longer holes.
• DIN/ANSI standard geometry — ensures dependable fit and predictable performance across common machine tools and setups.
• High‑performance, high‑speed precision — engineered to produce high‑quality holes with tight tolerances, achieving H10 accuracy when paired with proper feeds and speeds.

Exacting projects benefit from the A940’s purposeful design: precise dowel holes, through‑holes in steel or stainless, and deep pockets where uniform hole depth matters. This drill is a practical choice for automotive fixtures, maintenance workshops, and fabrication shops that require multi‑material versatility without swapping tools mid‑job.

Usage tips to unlock its full potential: set speeds and feeds according to material type, use a suitable cutting fluid on steel and stainless, and adopt a steady pecking approach for deep holes to prevent chip clogging and to maximize tool life. The result is consistently centered holes with minimal deflection and excellent surface finish.
