Dormer Pramet A170 23.00 mm HSS ST STRAIGHT SHANK JOBBER DRILL, 1/2IN SHANK

The Dormer Pramet A170 23.00 mm HSS straight shank jobber drill is a versatile, ready-to-use drilling solution built for professional shops and home workshops alike. With a 23 mm diameter and a 1/2" parallel shank, it fits standard handheld power tools and machine spindles, making it easy to tackle larger-hole work with confidence.

Designed for a wide range of tasks, this drill uses premium HSS material to handle steels, aluminum, and stainless steel. The steam oxide finish helps prevent material from sticking to the cutting edge, while the 118° conventional point provides a strong, easy-to-sharpen tip for clean starts and durable performance.

• 118° conventional point: Provides a strong tip that’s easy to re-sharpen, helping you maintain sharpness and consistent starts over many holes.
• Steam oxide finish: Reduces built-up material on the edge, supporting smoother cutting and longer tool life.
• 1/2" parallel shank: Enables secure, compatible use in conventional handheld power tools and machines, even with larger diameter drills.

With these features, the A170 drill delivers dependable, repeatable results across common metals. The combination of a robust HSS core, strong point geometry, and a practical 1/2" shank means fewer tool changes, faster hole creation, and cleaner finishes in both handheld and machine drilling applications.
