Dormer Pramet A123 3.30 mm HSS SHEET METAL STUB DRILL DIN 1897

The Dormer Pramet A123 3.30 mm HSS Sheet Metal Stub Drill (DIN 1897) is a compact, precision tool designed for thin sheet metal work. With a 3.30 mm diameter, it’s ideal for cleanly creating small holes in lightweight materials and fits into standard sheet-metal fabrication workflows.

Its 120-degree conventional point with a thin core (web) aids self-centering and reduces the push force needed to start a hole, helping you achieve accurate starts with less effort. The steam oxide finish helps prevent workpiece material from sticking to the cutting edge for smoother cuts, while the absence of body clearance during manufacture improves hole roundness and overall accuracy.

• Self-centering 120° point with thin web: Enables precise hole starts with less effort, reducing walking and improving first-pass accuracy.
• Steam oxide finish: Minimizes material buildup on the edge for cleaner cuts and easier chip evacuation.
• Precise manufacturing without body clearance: Improves hole roundness and consistency when drilling thin sheets for reliable results.

Designed for versatility, this premium HSS sheet-metal drill handles a range of materials including steel, aluminium, and stainless steel. Specifically optimized for thin-material drilling, it delivers consistent hole quality in everyday fabrication, maintenance, and light production tasks, helping you complete projects more efficiently with fewer reworks.
