8mm collet for Makita 3612 Router

[Speaker]

I’m hoping that the collective wisdom on this forum will be able to help me define the question to get what I need.

Background: my Men’s Shed have a Leigh Super 18 Dovetail jig with a set of 8mm shank Leigh dovetail cutters.

To use with the jig they have a Makita 3612 router with a guide bush insert.

The problem is that the collet on the router is 1/2” (12.7mm) and the cutters are 8mm.

We do have a 12mm to 8mm reducing sleeve but that is too loose.

the obvious solution would be to use a 1/2” to 8mm reducing sleeve - does anyone know if such a thing exists? And yes I have tried all sorts of searches but have not been able to get a definitive answer (I did ask Makita but am still waiting for them to call).

Another option might be to get an 8mm collet nut for the router, but again I have not been able to establish if such a thing exists.

If anyone can help with the question I need to be asking to get some clear answers for either of
these options I would very much appreciate it.

or, if there are any other options you can suggest that would be great as well.

Thanks,
Tony

Yup, Axminster sell a 1/2" to 8mm collet sleeve. I bought one the other week to use in my Makita, and it works just fine.

You could replace the collet and nut with a Muscle Chuck. It is an Allen wrench tightening chuck and it looks like the Type 4 with 8mm can be had to fit the Makita you have. A more expensive option than Luke mentioned but easier to use.

I'd imagine trend do a replacement collet too.

I have a Makita OEM 8mm collet for my Makita 3620 (and use it often), but the 3620 is 3/8" max, not 1/2".

Cheers, Vann.

This is a 3012.

@Luke Barnard - many thanks, that was exactly the help I was looking for. Only problem was having to find other stuff from Axminster to qualify for free postage

This is a 3012.

Which is of course, why I said "...but the 3620 is 3/8" max. not 1/2".

I figure if they make an 8mm collet for the 3620, then it's likely they make one for the 3612.

Cheers, Vann.
