Fine Pivot Drill Bit 0.6mm (Shank Dia. 1.0mm)

Tamiya Fine Pivot Drill Bit 0.6 mm with a 1.0 mm shank

A drill bit for fine modeling work: the cutting part is 0.6 mm in diameter and the clamping shank is thickened to 1.0 mm. That is the whole point of the Fine Pivot range - all the bits have the same shank, so they are changed in the holder without resetting the collet and without looking for the right jaw. The thicker shank moreover carries the bending load instead of the thin cutting part, so the bit is not so prone to snapping at the clamping point.

Use

• holes for the wire tubes of pitot tubes and antennas on aircraft
• drilling out the muzzles of small barrels and cooling holes
• holes for the pins of photo-etched parts, handles and clasps
• small holes in resin parts and instrument panels

Work tips

Six tenths of a millimeter is the diameter at which technique already decides. Mark the point beforehand with a sharp tip, so that the bit does not start traveling over the surface. Turn slowly and let the tip bite under the weight of the tool alone; the moment you press, the bit bends and breaks. With a deeper hole, pull the bit out every few turns and remove the swarf, because in a thin flute it clogs immediately. Drill into resin even more carefully, because the material is brittle and readily chips. If you need the hole exactly perpendicular, keep the bit short, with a minimum projection from the shank.

Who the drill bit is for

For aircraft modelers and builders of detail who work with thin wire and photo-etch and need holes that in the end are not visible as holes, but as a functional detail. It also suits a workshop where various diameters change often and constant re-clamping holds things up.

The drill bit is a sharp and very fragile tool. Keep it out of the reach of children and protect your eyes, because a broken tip flies off at great speed.
