The Dormer Pramet A117 7.30 mm HSS-E straight shank stub drill is a DIN 1897 precision drill built for tough metalworking tasks. Crafted from premium HSS-E (cobalt-enhanced high-speed steel), it delivers reliable cutting performance on hard materials, including tool steel. The 135° split point helps you start holes with confidence, reducing wandering and push force, while the bronze oxide finish minimizes sticking at the cutting edge for smoother cuts.

With a heavy-duty design, this stub drill is engineered for difficult materials and applications, delivering consistent hole quality and longer tool life in everyday workshop use.

• 135° split point for self-centering and reduced push force: Start holes accurately with less wandering and effort, improving first-pass accuracy on hard metals.
• Bronze oxide finish resists sticking and edge buildup: Maintains a clean cutting edge for smoother cuts and more consistent hole quality over time.
• Premium HSCO material for hard materials including tool steel: Provides durability and sustained performance when drilling tough materials where standard drills struggle.

This combination translates to faster, more reliable drilling with cleaner hole finishes and reduced downtime. The 7.30 mm diameter and DIN 1897 straight shank ensure smooth tool changes and stable performance in compatible chucks, while the heavy-duty design withstands demanding workpieces. It’s a dependable choice for engineers, machinists, fabricators, and hobbyists who value precision and consistent results in metal drilling.
