Tiny Holes. Rock-Solid Control. Precision Without Compromise.

When your modeling project calls for holes barely larger than a human hair, ordinary drill bits can quickly become a source of frustration. The Tamiya 74114 Fine Pivot Drill Bit is designed to make those delicate operations more accurate, reliable, and considerably easier to control.

Featuring an ultra-fine 0.3 mm cutting diameter and a reinforced 1.0 mm shank, this precision drill bit combines the accuracy of a micro-drill with the stability of a substantially thicker shaft. The stepped design allows the bit to sit securely in a compatible pin vise, minimizing wobble and helping you drill exactly where intended.

Manufactured from high-speed steel (HSS), the drill bit offers excellent cutting performance and durability. Its specially finished surface helps reduce the risk of breakage, an important advantage when working with such delicate cutting diameters.

For WWI aircraft enthusiasts, 0.3 mm is a particularly useful diameter for preparing rigging attachment points, control cable connections, and miniature fittings. It's equally valuable for creating precise holes in plastic, brass, aluminum, wood, and other suitable materials during detailing and scratch-building.

The bit is particularly suited to shallow precision drilling, where accurate positioning and minimal deviation are essential. A protective plastic storage case keeps the delicate cutting tip safe between modeling sessions.

Because when you're drilling holes smaller than a millimeter, being slightly off target is already a pretty big deal.

• Special blade finish helps reduce the risk of breakage.

• Ideal for shallow precision holes in miniature components.

• Suitable for plastic, brass, aluminum, steel, and wood with appropriate drilling techniques.

• Excellent for WWI aircraft rigging, control cables, miniature fittings, and scratch-building.

• Compatible with Tamiya 74050 Fine Pin Vise D, 74051 Fine Pin Vise S, and 74112 Fine Pin Vise D-R.

• Protective plastic storage case included.

For WWI aircraft rigging, mark the intended attachment point with a fine needle before drilling. Secure the 0.3 mm bit in a manual pin vise and rotate gently, keeping the tool perpendicular to the surface. Avoid excessive pressure and sideways movement, which can damage even reinforced micro-drills. For particularly delicate parts, consider drilling before final assembly to reduce handling risks.

Please Note: This drill bit is designed primarily for precision shallow-hole drilling. Although the reinforced shank improves stability, the 0.3 mm cutting tip remains delicate. A compatible pin vise is required and sold separately.
