Dormer Pramet A120 4.20 mm HSS ST STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A120 4.20 mm HSS Straight Shank Stub Drill (DIN 1897) is a compact, high-performance drill bit designed for metalworking tasks in tight spaces. With a straight shank and stub length, it delivers rigid, vibration-resistant performance in both handheld drills and machine setups.

Made from premium high-speed steel and sized at 4.20 mm, this drill bit is built to drill a variety of metals—including steel, aluminium, and stainless steel—with consistent accuracy. Its 135° split point, steam oxide finish, and precision-ground geometry help you start holes quickly, achieve cleaner finishes, and maintain reliable results across jobs.

• 135° split point for self-centering and reduced push force: The tip design starts holes precisely where you want, minimizes wandering, and reduces the effort required to begin cutting, helping you achieve accurate holes on the first pass.
• Steam oxide finish for reduced sticking and smoother cut: The oxide coating minimizes workpiece material from sticking to the cutting edge, improves chip flow, and contributes to cleaner hole finishes and less downtime cleaning.
• Premium HSS material for versatile material compatibility: Engineered to drill a range of metals—including steel, aluminium, and stainless steel—so you can handle diverse jobs with a single drill bit and reduce tool changes.

With the A120 drill, you gain reliable, repeatable results across common metals, quicker starts, and cleaner, more accurate holes. The combination of a self-centering point, oxide finish, and robust HSS construction helps you work faster, reduce rework, and keep your drill cutting smoothly through varied projects—from maintenance tasks to fabrication work.
