ChiloskitCollet Adapter 1/4 to 1/8, Collet Chuck Conversion CNC Engraving Bit Router Converter for Router Cutter Milling Bit,6 Pics

One day I will learn to take reviews with a grain of salt and stop letting them make me hesitant on my purchases. After reading the reviews of this product, it just seemed to be riddled with challenges. That has not been my experience, but my use may vary from others. I needed a reducer to utilize 1/8" shaft bits in my compact router that utilizes 1/4" shafts. I do a lot of detail work and needed a 1/32" end mill for fine work, but they do not sell them in a 1/4" shaft. These reducers seemed to fit the bill and they worked spectacularly. I inserted the reducer as far as it would go into my router collet, then added the bit, and tightened it up. The adapter held the bit and did not slip or break either piece. Now that I have 6 of them I hope they last the rest of my life. Good product and I would recommend them to anyone looking to utilize them in an application like I described.

Works great

Won't always be super accurate, but they work well enough. Now I can chuck little 1/8" shaft jewelry burrs and laminate trimmer bits in my router and that's all I wanted.

I previously purchased an Amana adapter and struggled to hold the collet and bit while inserting them into the collet. The adapter fit very loosely on the bit. These provide just enough friction to insert the bits and hold them securely while they are inserted.

I was trying to use my Dremel with small router bits. I picked these up to use the pits in my cordless regular router. They worked perfectly. Fit was good and performed well with zero complaints.

Getting 6 in a bundle is good. 4 are usable but 2 are undersize and the 1/8" shaft will not fit. The collet I used worked well and 4 is plenty for my usage. Pretty casual quality control.

Adapters fit easily into my 1/4" collett on my Bosch router and the bits fit easily into the adapter. I haven't measured runout but had no problem cutting out many small pieces for a doll house on my CNC in 1/8" plywood. For the price these are perfect for my needs.

I use these with a Rigid laminate router to fit Dremel accessories and other 1/8" cutters I down-cycle from work. The first one I tried worked perfectly. Holds fast and runs true. I only really need 1 to work and it did. If the other reviews are accurate, I can expect at least a few more to work too. Well worth it for the price.
