05.090.23 3-PIECE STEPPED HOLE DRILL SET MARCO TOOLS SPIN

Excellence in Drilling Sheets and Composite Materials

The Spin model, Cod. 05.090.23, was developed for maintenance professionals, installers, and body shop technicians who require perfectly circular, burr-free holes in thin-walled materials. Thanks to its stepped geometry, each tip allows for drilling of different diameters with a single tool, acting simultaneously as a hole drill and countersink.

Technical Features and Benefits

• Deformation-Free Drilling: The particular shape of the cutting edges is specifically designed to penetrate thin metal sheets without "tearing" or bending the material, guaranteeing a superior aesthetic and functional result.
• Material Versatility: Extremely effective on all types of metal (mild steel, aluminum, copper) and on thermoset or thermoplastic industrial plastics.
• Wide Operating Range: The set covers almost every standard drilling need thanks to the three included bits that allow you to range from small service holes up to large cable passages (32 mm).
• Load Capacity: Optimized for working on sheets and panels with a maximum thickness of 3 mm.
