Sleeved Centrotec bitholder
« on: October 01, 2018, 12:57 AM »
How can I get a sleeved Centrotech bitholder similar to this: https://smile.amazon.com/DEWALT-DW2054-4-Inch-Compact-Magnetic/dp/B0000225P8?keywords=DEWALT+DW2054&qid=1538369589&sr=8-1&ref=sr_1_1

I need to be able to stabilize the screw initially, and the sleeve that rotates freely and slides forward is very convenient. The one that came with my CXS kit neither slides nor rotates separately. 

Many thanks to all.

I've never seen what you're asking for.  Alternatively, you can use the DeWalt unit in the standard drill chuck that comes with the CXS.

Another option is to grind/file the extra groove into the Dewalt bit holder to "centrotec" it.

There are a couple thread on here showing how to do this.

If you really want and need that bit holder, I'd just Centrotec it. Some people have used a lathe while others have used a drill press. The lathe is definitely easier, however if it's only 1 bit, the drill press is fine.

Some of these standard 1/4" quick release shanks do fit in the centrotec chuck, they just don't lock, but there will be a friction fit..  But some don't fit at all without filing down the edges a hair.  So it's kind of hit or miss with other brands, but if you don't need it to lock and you don't want to mod it, that may be an option if you can find a store that has a few available to try on your centrotec.

or try the Snappy Adapters

I assume the 1/4" Drill Bit Adapter will suffice. They're made for round drill bits and come in different sizes, looking to get one for a pocket hole step bit.

One thing to watch out for when "centrotecing" a bit.   I did a countersink / counterbore bit and though there was enough room on the shaft to add the groove, there was not enough additional space between the added groove and the counter sink portion to allow the bit to be inserted into the Centrotec chuck far enough to engage. Not sure but that could be problem with "centrotecing" the sleeved bit.

 @dupe  That is an interesting idea to place a 1/4" hex into a 1/4" drill bit holder as an adapter. I have one. Need to check that out today.

   [doh]  Nope doesn't work. 1/4" hex bit is 1/4" across the flats. Too big.

hex head, round hole  [doh] [doh] [doh] good catch @SRSemenza

@koenbro Snappy has adapters from 1/8" (round) bits up to 3/8" each with +/- 0.01" clearance for setting. Take your favorite mag holder and check the diagonal.
