DIY slot and modelling drill 2.3mm

Precision to the tenth of a millimetre for your slot and modelling projects

When working at a reduced scale, the difference between a correct hole and a poorly executed one can ruin hours of preparation. The Tectime TT720 drill bit of 2.3 mm is designed exactly for that type of work: detailed interventions where diameter control is essential.

Main features

• Diameter: 2.3 mm, a very commonly used size in slot chassis preparation and static model assembly.
• Reference: TT720, from the Tectime tool range.
• Designed for use in fine DIY, slot, and modelling in general.

Applications in slot and modelling

This diameter of 2.3 mm is particularly useful in common operations in the slot and modelling workshop:

• Opening or enlarging holes in plastic or metal chassis to accommodate screws, axles, or inserts.
• Adjustment work on resin or injected plastic bodies.
• Preparation of parts for static models, figures, and dioramas.
• Any precision drilling that requires an intermediate diameter between 2 and 2.5 mm.

Recommended assembly and use

To achieve the best results with this drill bit, it is recommended to use it with a handheld micro-drill or a bench-top pillar drill set to low speed. In soft materials like plastic, working without excessive pressure prevents tearing of the material. In light metals, a few drops of lubricant will extend the tool's life and ensure a clean cut.

Frequently asked questions

What type of drill is this bit used with?

It is compatible with handheld micro-drills like Dremel, bench-top pillar drills, and any standard chuck that accommodates shanks up to 3.2 mm. Check the shank diameter before mounting.

Is it suitable for drilling metal slot chassis?

Yes, although for metal materials it is advisable to reduce the rotation speed and apply some lubricant to preserve the cutting edge of the drill bit and achieve a clean cut.

Can I use it for plastic or resin bodies?

Perfectly. In plastic and resin is where this type of small diameter drill bits works most comfortably. Low pressure and moderate speed are recommended to avoid cracking the material.

Does it come in a pack or is it a single unit?

The reference TT720 corresponds to a single 2.3 mm drill bit. If you need multiple units, you can add as many as required to the cart.

The Tectime TT720 is a 2.3 mm drill bit designed for slot car preparation, static model kits, and hobby dioramas. Perfect for precision drilling in plastic, resin, and light metal components, it is an essential tool for any serious slot car builder or scale modeller looking for clean, accurate results in small-format work.
