The Frost step drill is a high-speed steel (HSS) stepped bit that drills and progressively enlarges holes from 4mm up to 12mm with a single tool.
Use it to bore and step out clean holes in thin metal, sheet and similar materials without changing bits.
Frost 4 12mm Hss Step Drill is a high-speed steel step drill designed for precise drilling in various materials including sheet metal, aluminium, plastic, and fibreglass.
The Frost 4 12mm Hss Step Drill is engineered for efficiency and control during drilling tasks. Constructed from high-speed steel, this drill features a spiral flute design that minimises vibration, allowing for greater accuracy through each step. The fixed drilling steps eliminate the need for pre-drilling, making it suitable for sheet metal applications. Additionally, the three-flat shank is compatible with 3-jaw chucks, ensuring a secure grip. As each step is drilled, the subsequent step deburrs the previously drilled hole, enhancing the overall finish.
