SET. DRILLS CYL. REF. 505

Precision in Every Pass: the Cylindrical Drill Bit Set Ref. 505

When fine work matters —and in modelling and slot it always does— having the right drill bits makes the difference between a clean fit and a ruined piece. The Cylindrical Drill Bit Set Ref. 505 (CH01505) is designed for those delicate interventions: enlarging, cleaning, or adjusting holes in bodies, chassis, motor mounts, and other components where total control is essential.

Main Features

Cylindrical drill bits are characterised by their straight cutting geometry, making them particularly useful for working on soft or semi-soft materials common in the hobby: plastic, resin, brass, lightweight aluminium. Their cylindrical profile allows for a constant diameter along the entire useful length, ensuring clean holes without deviations.

• Manufacturer reference: 505 (Ministry of Hobby code: CH01505).
• Cylindrical geometry for controlled and precise cuts.
• Suitable for materials commonly used in modelling and slot preparation.
• Set format: several sizes included in the same case.

Applications in the Hobby Workshop

This type of drill bit finds its natural place in numerous everyday tasks of the enthusiast:

• Slot and car preparation: enlarging holes in chassis to adjust axles, mounts, or screws; cleaning holes in plastic or resin bodies.
• Static models: opening or reaming holes for antennas, barrels, handrails, and details in photo-etched parts.
• Figures and dioramas: working on resin or metal parts where a precise hole is needed for rods, joining pins, or positioning axles.

Recommended Assembly and Use

To get the most out of these cylindrical drill bits, it is advisable to use them with a micro-drill or hand lathe at moderate speed. Applying gentle and constant pressure prevents the drill bit from breaking and the material from fraying, especially in injected plastic or resin. In soft metals like brass, a few drops of cutting oil significantly extend the tool's life.

Storing the drill bits in their original case after each use protects the edges and makes it easier to locate the exact size for the next project, without wasting time rummaging through the drawer.

Who is this drill bit set for?

Whether you are preparing cars to compete in a slot club or building static models with the level of detail demanded by high-end hobbies, a good set of cylindrical drill bits is one of those tools that always fall short when you don't have them. The Ref. 505 covers the most requested sizes in a single case, eliminating the need to search for loose drill bits for each intervention.

Frequently Asked Questions

What materials can I work with these cylindrical drill bits?

They are suitable for plastic, resin, brass, and lightweight aluminium, common materials in modelling, dioramas, and slot car preparation. They are not suitable for hardened steel or high-hardness materials.

Do I need a specific tool to use them?

The most recommended tool is a micro-drill or hand drill (like Dremel or similar) at moderate speed. They can also be used with a precision chuck for very delicate work where direct touch is required.

How many drill bits are included in the set and what sizes?

Detailed information about the exact number of pieces and the included diameters is not available at this time. We recommend contacting us directly to confirm the contents of the case before placing your order.

Are they compatible with standard chucks?

Cylindrical drill bits are usually compatible with standard shank chucks. However, check the shank diameter against the manufacturer's data to ensure proper coupling with your tool.

How do I keep the drill bits in good condition?

Clean them after each use to remove chips and material residues. Store them in their case, avoiding contact between the edges. When working on metal, using cutting oil significantly extends the tool's lifespan.

The CH01505 cylindrical drill bit set Ref. 505 is a precision hobby tool designed for slot car preparation, static scale modelling, and diorama work. Ideal for drilling and enlarging holes in plastic, resin, and light metal components, it provides the accuracy and control that enthusiasts and club racers demand in their workshop. A reliable addition to any serious hobbyist's toolkit.
