JIUWU 6.35mm to 3.175mm 0.125 incehs Engraving Bit CNC Router Tool for 6.35mm Collet

These collet adapters are good quality items at an affordable price. I use them to enable my router to use CNC bits and bits designed for use in a rotary tool when I'm doing engraving or carving. I find it wise to purchase a pack of them as opposed to a single adapter, because it's so easy to find them and so difficult to find them once they hit the floor of the shop.

I had lost my collet to my roto zip so I ordered a new one .. before my new collet arrived I found the collet I had lost. Now I have two...

It works! I needed one, they had it, i bought it, it worked...

Worked well and expected

The OD fits a 1/4" collet, but unfortunately the ID is a bit small for a 1 /8" bit.

Junk. Needed this to put a 1/8 bit in a 1/4 inch collet. The 1/4 end is too small and the bit won't tighten and just falls out.

Fitted Dewalt 26200 router perfectly and allowed use of 3.175mm bits in 1/4 inch router. No problems

Very good

Ideal.... Worked a treat.....

Part dimensions not as described as it was nearer 6mm so could be pulled out of a fully tightened chuck.
