Have an old (second hand) Bosch POF50. Setting up to use it to drill 5mm shelf pin holes for 32mm system and a drawer front drilling jig.

Almost ready to go and the 5mm spiral bit drills a 5.5mm hole. I see Gerhard said the POF50 was "professional quality". (https://www.woodworkforums.com/archiv.../t-104461.html). I'm inclined to differ on that. The collet cone seems not well designed - too short to maintain accurate alignment and the plastic body is not so robust as aluminium. Router shaft seems OK with small end play but not obvious lateral play. A bit of a fiddle with bit and collet and managed to get the 5.5mm hole down to 5.2mm. Been trying to figure how to get the play out of the shaft/collet system and figured I may as well look to something better, since I don't have access to a machine tool shop.

I can't bring myself to take an Ozito home. All the low end router rotating depth stops look particularly cheap and nasty. Trimmers from Bosch, Makita, etc) look nice but with a plunge base end up close to $300 or more. (More than I paid for my Triton TRA001.) Bosch don't list the plunge base in Oz, but do in USA for a "Bosch Colt".

Variable speed die grinder would fit in the POF50 base with 43mm collar, but they all seem to cost about $300. Seems odd that they charge 3x more than for an angle grinder.

Ended up getting a fixed speed Makita DG0602 die grinder ($130). It has a 43mm collar but you'd never know it from the Makita documentation. The pictures make it look like plastic but it is acutally a rubber boot over the aluminium casting. Grumpy salesman tried to tell me the dimension was 43mm outside the rubber boot and didn't want to take off the boot to let me measure the metal collar. Only the Makita global site (makita.biz) has proper product information describing the aluminium 43mm collar. The Makita collar is cast and not machined, so doesn't quite play perfectly with the Bosch POF50 router base, which will be a pain for future alignment. The depth stop top nut doesn't fit by the Makita shoulders. The shoulders don't sit flat. It does attach solidly. Collet cone is long and well made. So, overall I am happy I can drill the shelf pin holes at advertised diameter and get a die grinder for other uses. A full range of collets are available somewhere. 8mm will be nice to have.

Gerhard in the other thread mentioned being able to use an "accessory edge guide" to use the grinder as a trimmer. Anyone know who makes such an accessory edge guide that will fit a 43mm die grinder collar??
