Dormer Pramet A920 8.30 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK STUB DRILL DIN/ANSI

The Dormer Pramet A920 is a high‑performance HSS‑E straight shank stub drill designed for reliable metalworking across a range of materials. With an 8.30 mm diameter and a DIN/ANSI straight shank, it fits standard chucks and holders for quick setup and consistent results, making it suitable for engineers, buyers, tradespeople, hobbyists, and shops that need dependable hole quality.

Key features are engineered to improve start accuracy, drilling efficiency, and material versatility: the 130° point promotes self‑centering starts and reduces push force, the parabolic flute design enables deeper holes in a single pass, and the premium HSS‑E material supports drilling across steel, aluminium, and stainless steel with high precision.

• 130° Point for Self‑Centering and Reduced Push: Delivers easier starts and cleaner holes by guiding the drill precisely into the workpiece, lowering operator effort and improving accuracy.
• Parabolic Flute Design for Deeper Holes in One Pass: Optimizes chip evacuation and stability, enabling efficient drilling of longer depths without re‑entry or wander.
• Premium HSS‑E Material for Versatile, High‑Quality Drilling: Delivers reliable performance across common metals, maintaining hole quality at higher speeds and feeds with tight h10 tolerance.

This drill combines a bright finish to help prevent material from sticking to the cutting edge with a robust HSS‑E composition, delivering durable performance and consistent results across multiple materials. Its design supports fast, repeatable hole quality, reducing rework and downtime while keeping you productive on demanding projects.
