The Dormer Pramet A117 1.30 mm HSS-E Straight Shank Stub Drill (DIN 1897) is a precision small-diameter drill designed for clean starts and reliable hole quality in metalworking. It’s built for a wide audience—from engineers and buyers to tradespeople and hobbyists—delivering consistent performance in challenging materials.

With a 1.30 mm diameter and a straight shank that fits standard chucks and holders, this drill is ideal for tight-tolerance work where accuracy matters. Its feature set—118° split point, bronze oxide finish, and premium HSCO material—enhances starting reliability, reduces sticking, and enables drilling in hard materials including tool steel.

• 118° split point: Creates a strong, self-centering tip that starts cutting immediately and is easy to re-sharpen, reducing wandering and improving hole accuracy.
• Bronze oxide finish: Helps prevent workpiece material from sticking to the cutting edge, promoting cleaner cuts and a better surface finish with less built-up edge.
• Premium HSCO material with heavy-duty design: Combines a cobalt-enriched composition with a robust construction to deliver dependable performance for hard materials, including tool steel, and withstand demanding applications.

This drill is engineered for real-world use—delivering precise holes, durable edge life, and reliable operation across a range of metals. Its tough build and optimized tip geometry help you complete jobs faster, with fewer reworks and consistent results from the first hole to the last.
