Small Holes. Serious Precision. Every Millimeter Matters.

When precision is measured in fractions of a millimeter, your choice of drill bit can make all the difference. The Tamiya 74127 Fine Pivot Drill Bit combines a precise 0.6 mm cutting diameter with a reinforced 1.0 mm shank, delivering the stability and control needed for delicate scale modeling work.

Its clever stepped-shank design provides greater resistance to breakage and helps reduce drilling deviation compared with conventional micro-drills of uniform diameter. The thicker shaft sits securely in a compatible pin vise, while the fine cutting tip creates clean, accurately positioned holes.

The drill bit features a durable construction and a high-quality cutting finish, helping produce precise openings in plastic, brass, other suitable metals, and wood.

For WWI aircraft enthusiasts, 0.6 mm is a useful diameter for preparing mounting points, installing small locating pins, and creating openings for control cables or rigging hardware. It's equally valuable when detailing cockpits, modifying plastic components, or fabricating custom parts for scratch-building projects.

With a 4.8 mm flute length, the bit is particularly suited to controlled, shallow drilling operations. A protective plastic storage case keeps the delicate cutting tip safe between modeling sessions.

Because sometimes the difference between a perfect fit and a frustrating afternoon is just six-tenths of a millimeter.

When drilling mounting holes for miniature aircraft fittings or locating pins, first mark the intended position with a fine needle. Secure the 0.6 mm bit in a manual pin vise and rotate gently, keeping the tool perpendicular to the surface. For delicate components, drill before final assembly whenever practical, and test the fit before applying adhesive.

Please Note: Although the reinforced shank improves stability and resistance to breakage, the 0.6 mm cutting tip remains delicate. Avoid excessive pressure and sideways movement. A compatible pin vise is required and sold separately.
