Dormer Pramet A920 4.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK STUB DRILL DIN/ANSI

The Dormer Pramet A920 4.50 mm HSS-E straight shank stub drill is a versatile, high‑performance drilling solution designed for a wide range of materials and applications. With a DIN/ANSI straight shank, it fits a broad array of holders and machines, making it suitable for engineers, machinists, tradespeople, and hobbyists who value reliable hole quality in compact tool setups.

Equipped with a 130° point for self‑centering and reduced push force, a bright finish that minimizes workpiece material sticking to the cutting edge, and a parabolic flute design that enables deeper holes in a single pass, this drill pairs precision with efficiency. Constructed from premium HSS‑E, it is capable of drilling steel, aluminium, and stainless steel at high speeds and feeds, delivering consistent h10‑tolerance holes.

• 130‑Degree Point for Self‑Centering and Reduced Push Force: Helps start holes accurately and minimizes guiding effort, improving control and reducing wandering during initial contact.
• Bright Finish to Reduce Material Sticking: Keeps the cutting edge cleaner, promoting smoother entry and easier chip evacuation for better surface finish.
• Parabolic Flute Design for Deep Holes in One Pass: Efficient chip evacuation and stable drilling that enables deeper holes without multiple passes, boosting productivity and reducing tool changes.

Designed for demanding work environments, this 4.50 mm HSS‑E stub drill delivers dependable performance across common metal alloys while maintaining precise hole geometry at high speeds. It helps you streamline setups, minimize rework, and expand your capabilities—from quick maintenance tasks to production runs—without sacrificing accuracy or surface quality.
