The set includes a drill holder with a swivel head, two reversible collets for multiple drill capacities (one stored in the handle), and 20 precision drill bits ranging from 0.3mm to 1.6mm. The drill bits are supplied in a sliding storage case.

What drill bit sizes are included?

The set comes with 20 drill bits in the following sizes: 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm, 0.9mm, 0.95mm, 1.0mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, and 1.6mm.

What types of railway modelling tasks is this drill set suitable for?

This precision drill set is ideal for delicate, intricate work on model railway projects, such as drilling fine holes in components, detailing work, and other small-scale tasks where control and accuracy are important.

How do the reversible collets work?

Each collet has two different gripping ranges, one on each end. You simply remove the collet, flip it around, and reinsert it into the drill holder to accommodate different drill bit diameters. This allows the drill holder to accept multiple bit sizes with just two collets.

How is the extra collet stored?

The extra collet is stored inside the handle of the drill holder. This keeps it protected and ensures it is always close at hand when you need to change drill capacities.

What makes the swivel head useful for model railway work?

The swivel head allows the drill holder to rotate smoothly in your fingers while the end of the handle rests comfortably in your palm. This gives you fine control and reduces strain during slow, precise drilling on small model parts.

Why are my drill bits slipping in the collet?

If a bit is slipping, it is usually because the collet is not gripping the correct size. Try the following:

• Check that you are using the end of the collet that best matches the bit diameter.
• Ensure the bit is fully seated in the collet before tightening.
• Tighten the drill holder firmly, but without over-tightening.

What should I do if a drill bit feels loose in the holder?

Remove the bit and collet, then:

• Flip the collet and try the other end to see if it grips better.
• Confirm you are using a bit size that falls within the collet’s capacity.
• Clean any dust or debris from the collet and bit shank before reinserting.

Why is the drill not turning smoothly when I use the swivel head?

If the rotation feels rough or stiff:

• Check that you are holding the swivel head lightly in your palm, not gripping it tightly.
• Make sure there is no debris caught around the swivel joint.
• Use gentle, steady finger movements on the shaft rather than forcing it.

What can I do if the drill bit keeps breaking in delicate work?

Bit breakage often comes from too much pressure or twisting. To reduce breakage:

• Apply very light pressure and let the bit do the cutting.
• Use the smallest bit that is appropriate, but avoid forcing ultra-fine sizes through hard material.
• Keep the drill straight and avoid side-loading the bit.

The sliding case is hard to open. How should I handle it?

If the sliding case feels stiff:

• Open it slowly and evenly, keeping it level so bits stay in place.
• Check that no drill bits are protruding or caught in the lid.
• Avoid forcing the case open; gentle pressure along the sliding direction works best.

How do I insert a drill bit into the holder correctly?

To insert a bit:

• Loosen the drill holder and remove the collet if needed.
• Select the collet end that best fits the bit’s diameter.
• Insert the bit fully into the collet, leaving only the required length exposed.
• Place the collet back into the holder and tighten securely.

How should I hold the drill for precise work on models?

For fine control, rest the swivel head in your palm and use your thumb and fingertips to turn the shaft. Support the workpiece firmly and keep your wrist steady so the bit enters the material straight and slowly.

Can I change collets while working on a project?

Yes. You can switch between the two reversible collets as needed:

• Loosen the holder and remove the current collet.
• Retrieve the spare collet from the handle if required.
• Select the appropriate end for your new bit size, insert it, and retighten.

How can I keep the drill bits organized while assembling and detailing?

The included sliding case is designed to keep the bits safe and easy to access. Keep each bit in its designated slot and return it immediately after use so you can quickly find the size you need during assembly and detailing sessions.

Any tips for drilling small holes before painting?

It is often easier to drill all necessary holes before painting:

• Mark hole positions lightly so you can see them clearly.
• Start with a smaller bit if you are unsure of the final size, then step up.
• Clean away any swarf so primer and paint sit neatly around the drilled areas.
