Half a Millimeter. Full Control. Precision Where It Matters.

In scale modeling, the smallest details often make the biggest difference. The Tamiya 74116 Fine Pivot Drill Bit is designed for those delicate drilling operations where accuracy, stability, and a steady hand are essential.

Featuring a precision 0.5 mm cutting diameter and a reinforced 1.0 mm shank, this specialized drill bit combines the finesse of a micro-drill with the improved stability of a thicker shaft. Its stepped design allows it to sit securely in a compatible pin vise, reducing wobble and helping you create clean, accurately positioned holes.

Manufactured from high-speed steel (HSS), the bit delivers excellent cutting performance and durability. Its specially finished cutting surface helps reduce the risk of breakage, making it particularly useful for delicate drilling tasks where conventional micro-drills can be frustratingly fragile.

For WWI aircraft enthusiasts, 0.5 mm is a versatile diameter for preparing rigging attachment points, control cable connections, and mounting holes for miniature fittings. It's equally useful for installing locating pins, modifying cockpit components, and creating precise openings in scratch-built structures.

With a 4.0 mm cutting flute length, the bit is particularly suited to shallow precision drilling in plastic, brass, aluminum, steel, wood, and other suitable materials.

Supplied in a protective plastic storage case, this little precision instrument deserves a permanent place in any serious modeler's toolbox.

Because half a millimeter might sound insignificant. Until it's the difference between a perfect fit and starting all over again.

When preparing rigging attachment points on WWI aircraft, mark the intended drilling position with a fine needle before introducing the drill bit. Secure the 0.5 mm bit in a manual pin vise and rotate gently, maintaining a perpendicular angle to the surface. For mounting delicate components with metal locating pins, test the fit before final assembly to avoid unnecessarily enlarging the hole.

Please Note: Although the reinforced shank improves stability and resistance to breakage, the 0.5 mm cutting tip remains delicate. This drill bit is intended primarily for shallow precision holes. Avoid excessive pressure and sideways movement. A compatible pin vise is required and sold separately.
