1/4'' to 1/8'' Collet Reducer
1/4'' to 1/8'' Collet Reducer

This collet reducer lets you use a wide array of 1/8'' shank router bits and cutters in any router with a standard 1/4'' collet. An 1/8'' shank is a common size on specialty ''miniature'' router bit sets, so this is the perfect accessory for highly detailed work. The compression slot provides a tight grip on the bit/cutter.

Works as expected, runout is acceptable. A little pricy, but what isn't?

Recommended by others to address issues with 1/8" bits breaking in a DeWalt 611 mounted in an XCarve CNC. The price was low enough that it was worth it to at least see if it would resolve my issue.

Will this work for a Dewalt DWP-611 router ?
David P on Jul 20, 2015
BEST ANSWER: Yes. Any router with a 1/4" collet should be able to use this.
Is it safe to put in a cnc with a 3hp motor?
Phaines on Jan 6, 2019
BEST ANSWER: Yes. I used it to retain a 1/8 dia pin router in a standard router for overhead
shallow work in aluminum, plastic and brass.
i have this 30 year old black and decker (not labeled DeWalt) 1/4 inch router with a nut to tighten the collet. The factory collet is shaped almost like a diamond and its only about 1/4 inch long.
Is this reducer tapered to supply the squeezing pressure to hold the bit ? I ask because it looks pretty long and also looks straight.
William V on Apr 13, 2017
BEST ANSWER: There is no taper on the reducer, the bit is held by the squeezing pressure supplied by the collet. So you would need a 1" deep, 1/4" round collet for your reducer, otherwise the runout will become a problem. Your best bet would be to buy the right collet for your router.
