## Description

Set of 10 mini tungsten steel drill bits, ideal for making fine holes in PCBs with CNC or MiniCNC milling. Covers diameters from 0.1 to 1.0 mm, has a standard 3.175 mm shank for precise clamping, 38 mm length for drilling stability, delivered in a plastic case for organization and protection.
Drill set composed of 10 pieces enclosed in a plastic case, from 0.1 to 1mm in diameter.
They are made of tungsten steel and are used to make holes in PCBs, with a CNC cutter.
Careful! They are resistant to pressure (perpendicular drilling) but do not withstand bending well. Use exclusively with CNCs and MiniCNCs. Manual drilling can lead to their breakage, especially those with a small diameter.
They can also be used as a tool for cleaning the print nozzles (print head) of 3D printers. Avoid bending the drill bit.
