Applications in slot and modelling

In slot preparation, small diameter drill bits are essential for adjusting guides, enlarging motor mounting holes, working on axle anchors, or making small modifications to chassis and bodies. The 2.2 mm diameter covers one of the most common sizes in these types of operations.

In static modelling, figures and dioramas, this drill bit allows for the opening of rod passages, anchoring metal elements, working on ventilation holes in bodies, or preparing pieces for assembly with pins.

Recommended mounting and use

Compatible with handheld mini-drills or precision column drills like Dremel or similar. To achieve the best results, work at a moderate speed and with constant pressure, especially on injected plastic, to avoid vibrations that may damage delicate pieces.

Frequently asked questions

What type of materials is this drill bit suitable for?

It is primarily suitable for plastic, resin, and lightweight materials commonly used in slot and modelling. It is not designed for drilling hard metals or high-density abrasive materials.

What tool is it used with?

It is mounted on a precision mini-drill, rotary drill like Dremel, or handheld chuck. Ensure that the chuck accommodates the drill bit shank before use.

Is it a single-use drill bit or can it be resharpened?

For drill bits of such small diameter, home resharpening is neither common nor recommended. When the edge loses precision, it is most practical to replace it.

What is the difference between a 2.2 mm drill bit and a 2.0 mm drill bit in slot?

0.2 mm can make the difference between a tight fit and a loose fit. In slot, the choice of the exact diameter depends on the screw, rod, or axle you are going to accommodate, so it is advisable to measure always before drilling.
