Dormer Pramet A117 6.90 mm HSS-E STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A117 6.90 mm HSS‑E straight shank stub drill is a precision metalworking drill built for engineers, tradespeople, and serious hobbyists. With a DIN 1897 straight shank and a 6.90 mm diameter, it fits standard chucks for reliable performance and clean starts. Its 135° split point centers the drill and reduces the push force needed, helping you begin holes precisely with less wandering.

Made from premium HSCO material and finished with a bronze oxide coating, this drill resists wear, minimizes material sticking to the cutting edge, and delivers consistently accurate hole sizes even in harder metals. The heavy‑duty design is built for demanding applications, providing durable performance when drilling tool steel and other tough materials.

• 135° split point for self-centering: starts holes cleanly with less drift and reduced driving force, speeding up setups and reducing rework.
• Bronze oxide finish to prevent sticking: lowers chip buildup on the edge, extending tool life and maintaining a sharper cutting edge over more holes.
• Premium HSCO material with heavy‑duty construction: delivers reliable performance in hard materials (including tool steel) and stands up to challenging applications for longer tool life.

This drill helps you work more efficiently by delivering accurate hole sizes, smoother starts, and longer service life in tough metals. Its robust construction and wear‑resistant materials reduce downtime, minimize edge dulling, and provide consistent results across demanding projects.
