Assists in drilling 1 mm diameter holes on the end and sides of the round bar.
- Compatible with diameters of 2, 3, 4, and 5 mm
- A jig for making straight holes in the core (end face) and side surface.
- Only for drill blades with a diameter of 1 mm.
- If you want to make a hole smaller than 1 mm in diameter, use a drill blade with a 1 mm shaft and a small diameter blade at the tip (however, the total length of the blade must be 18 mm or more for core and end face machining).
