Inside Diameter: Ø0.8mm
The 0.8mm Mini Replacement Collet is a specialized precision component designed for the most delicate and intricate
rotary tool applications. Engineered specifically to accommodate micro drill bits and ultra-fine engraving burrs,
this collet provides the snug, high-tension grip required for tasks where accuracy is measured in fractions of a
millimeter. It is an indispensable tool for hobbyists and professionals working on high-detail projects such as
printed circuit board (PCB) repair, watchmaking, and micro-model construction.
Constructed from high-quality materials, this replacement collet is built to withstand the heat and friction of
high-RPM operation while maintaining perfect concentricity. By ensuring your accessories are perfectly centered, it
eliminates the ‘wobble’ or run-out that often leads to broken bits or damaged workpieces. This level of stability is
essential when performing fine etching on glass, metal, or wood, providing you with the control needed for a
professional, burr-free finish.
Installation is straightforward and fast, making it an ideal replacement for worn-out or lost factory collets. It is
compatible with most standard mini rotary tools and hand-held grinders, seamlessly integrating into your existing
kit. Whether you are a jewelry designer working on fine filigree or an electronics enthusiast drilling precision
pilot holes, this 0.8mm collet ensures your tool remains as precise as your hands require.
How to use a Collet:
- Insert the collet into the tool shaft if not already installed.
- Place the collet nut over it — but do not tighten yet.
- Insert your bit or accessory shank.
- Hold the tool’s shaft lock button.
- Tighten the collet nut using the collet wrench until firmly secured. Do not over-tighten — this can deform the collet.
