The Dormer Pramet A123 4.90 mm HSS Sheet Metal Stub Drill is a precision tool designed for drilling thin materials with confidence. Whether you’re setting up a jig, finishing a prototype, or performing routine fabrication, this drill delivers consistent, clean holes with minimal effort.

With a 120-degree conventional point and a thin web, it starts true, self-centers, and reduces the push force required. The steam oxide finish helps prevent workpiece material from sticking to the cutting edge, keeping the drill working smoothly. Manufactured without body clearance, it enhances hole roundness for improved accuracy. Made from premium HSS, it is suitable for drilling a range of materials, including steel, aluminium, and stainless steel, and is specifically optimized for sheet metal work in accordance with DIN 1897.

• Self-centering 120° point with thin web: Starts quickly and centers itself on thin sheets, reducing wandering and minimizing the effort needed to begin drilling.
• Steam oxide finish: Helps prevent material sticking to the cutting edge, resulting in cleaner cuts and less built-up edge during sheet metal drilling.
• Premium HSS with improved hole roundness: Durable, versatile for steel, aluminium, and stainless steel, and manufactured without body clearance to enhance hole accuracy and repeatable results.

Choosing this drill supports faster, more reliable sheet metal work by delivering accurate starts, clean holes, and dependable performance across common metals. Its DIN 1897 specification and 4.90 mm diameter fit standard tooling setups, helping you reduce rework and downtime while improving overall project quality.
