1.5 mm Drilling Head

U-STAR 1.5 mm modeling drill bit

Drill bits are a consumable tool that a modeler buys according to what is being built at the time. A diameter of 1.5 mm is among the most used: it is big enough for a drill to last more than a few holes and at the same time small enough for most detailing work in all the ordinary scales. It is clamped in a pin vise or in a mini drill.

Where a diameter of 1.5 mm suits

Typically for holes for handles bent from wire, for mounting antennas and masts, for counterboring under the tubing of replacement barrels and exhausts, and for preparing the pins on which two parts hold together. It is also used to lighten solid shapes, when a plastic tube or nozzle is meant to look hollow, and to open out holes a pin from another part will not fit into.

How to work with it

• Mark the spot beforehand with a needle or the point of a knife, otherwise the drill will slide across smooth plastic.
• Drill at right angles and without pressure; side force is what breaks thin drills.
• Work up to a larger hole from a smaller diameter; the result is cleaner.
• Keep withdrawing it and clearing the swarf, so that the flutes do not clog.
• Support or clamp the part, so that it does not twist under the drill.
• Before you buy, check that the diameter of the shank will fit into your chuck.

Who it is for

For modelers who add detail to models and do not want to rely on what is in the box. This is a tool, not a kit or an accessory for a particular model.
