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 well, no runout
I put this in my CNC router to use 1/8" shank engraving bits. If you have ever engraved using a CNC, you know that even the slightest runout will ruin a small engraving. This thing works very well. I am using it in a Bosch 1617 router with the standard Bosch 1/4" collet.

Just Right For Extending the Cutter Of My DIY CNC Router
The two reducing sleeves I ordered arrived quickly, in about a week.

The sleeve has a good, tight fit on the Roland long 1/8" shaft extended 1/16" cutter that I used for my test.

There seems to be a step or a taper at the nominal "bottom" of the reducing sleeve so that a 1/8" shaft stops about 1/8" before reaching the end of the sleeve.

I'm happy with that as it probably means that in addition to the grip of the chuck transmitted through the sleeve to the endmill there is also that step holding the shaft from being pushed inside my router by pressure against my work.

The endmill and reducing sleeve combination seems to be well centered--I don't notice any vibration like I've seen in previous experience with off center bits, and the cutting is as clean as I've come to expect from my machine.

The small projects I'm currently creating are perfect for this tool and sleeve combination. I can cut small text sections about 0.10" deep in one pass with the tiny cutter and then make several deeper passes around the text block to cut it 0.36" deep and remove the part from my soft pine sheet.

Rusty S on Jul 1, 2018
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.
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.
