router trim bit - Thai terminology

[gamb00ler]

I'm looking for a router bit to cut an acrylic countertop opening for an undermount ceramic sink.  The cabinet crew opened the boxes for the sinks and must have tossed out the template that is usually included with the sink.

 

The type of bit I'm looking for has a bearing at the lower end so that the router will trace out the shape of the ceramic sink.

 

Probably @sometimewoodworker will understand immediately what I'm looking for and hopefully knows the Thai name for this type of bit.

 

I did a little further reading and I think what is needed is an adjustable rabbiting bit.

I guess that is what you are looking for:

You can also search for a picture of an item (in Englich) and then use that picture to search i.e. in Lazada.

It is hard to see if there are adjustable rabbiting bits in that set.  For precise countertop/sink installations the diameter of the bearing and the height of the cutting edge both must be adjustable.  For that price, I doubt that the precise required bit is included.

My idea was to give you something to start, like the Thai name.

Maybe search for that or similar items from the same manufacturer and/or seller.

Maybe a trip to ITOOLMART Toolshop is in order. South of the airport so not far from Hang Dong

The standard is a flush trim or pattern bit

 

they are available with top bearings (easy to find) bottom bearings (big bit small shank) and dual bearings.

 

you can put the template on the surface (easy) or underneath (not so easy)

 

While you can use a rabbiting bit with different bearings like these 

you will not find them in Thailand and they are almost certainly a poor choice for the job.

Ideally the countertop should opening have a very small overhang that will somewhat conceal the joint between the ceramic sink and the acrylic countertop that needs to be sealed with silicon.  That's why I was hoping for a bit where the bearing diameter could be changed.  As it is, they are using free hand router style to estimate/guestimate the appropriate overhang.

Both of those are a bodge job.

you should make a template out of MDF and use that after using a jigsaw to clear the largest part out.

 

I hope they don’t make a dog’s dinner of the job

 

FWIW the granite guys did an acceptable job, but on overlay items.
