A specially designed hexagonal shaft drill bit specially designed for model making!
You can dig holes safely without worrying about it spinning freely.

A set of 5 pieces with a 4mm hexagonal shaft and drill diameters of 0.5mm, 0.6mm, 0.7mm, 0.8mm, and 0.9mm .

-The hexagonal shaft fits securely into the connection, so there is no need to worry about it spinning freely, allowing you to work with peace of mind.

- Compared to general drill bits, the overall length is shorter and the distance to the target is closer, making it easier to aim and control.

- The tip of the drill bit is designed with a blunt angle, so it can dig shallowly and make holes without penetrating thin plastic boards. It
　digs more slowly than a sharp-edged cutting edge, so it is less likely to shake and the hole is less likely to become distorted. The edges of the dug hole are also finished neatly.

What's more, if you use
the separately sold magnetic " Quick Power Pin Vise
", you can easily attach it by simply inserting it! It's very easy to attach and detach the pin vise, which increases your work efficiency!
