Uxcell Router Collet Adapter – 12.7mm (1/2") To 6.35mm (1/4"), Carbon Steel, Black Oxide, For CNC & Woodworking Routers

About This Product

This uxcell collet adapter lets you use smaller 1/4-inch shank bits in your 1/2-inch collet router or CNC machine – handy when you have a big router but want to run smaller bits without swapping collets.
The outer diameter is 12.

7mm (1/2-inch) and the inner opening is 6.
35mm (1/4-inch).
Total length is 27mm.

Made from carbon steel with a black oxide finish that resists corrosion and wear.

It gives you a tight, stable grip on your bit so there's no wobble or chatter during cutting.

Just slide it into your existing collet and tighten normally.
Works well with wood routers, engraving machines, and CNC spindles.

Great for when you need precision routing with fine bits but only have a 1/2-inch collet setup.

Simple, effective, and cheap compared to buying a whole new collet set.

Keep one in your tool drawer for those times you forget to switch collets before a job.
