Router bits and templates

I'm looking for some bits and templates for my router to make a sub box but this stuff can get expensive quick. Any recommendations for decent bits that won't break the bank? I have a 1/4" router.

Here's what I need:

1/2" roundover
Rabbeting bit
Flush trim bit
Maybe small round over like 1/8" or 1/16"

Templates/guides for this:
4", 4-1/2"', 11-1/8", 13" holes
5" corner radius, 1/4" corner radius

The key to cutting plastic is to do multiple passes. Let's say you're doing a round over. Make 3 or 4 passes, dropping the bit. Let the bit and part cool and just shave a couple thousandths off on your final cut.

Always use a conventional cut, (blade cuts into material) vs a climb cut, (opposite and dangerous with hand held tools).

Should be clean and melt free.

Pretty much the same thing if making a dado. Keep your cuts around 1/16" as you drop down. As you get accustomed to this work you can get more aggressive.

When flush trimming, rough trim your part as close to the completed size as possible. Then trim.

One of the most important parts when you're learning to hand held rout, is to hold the router steady and firm while keeping firm pressure down to keep the tool perpendicular.

The Makita trim router is a good choice and has good speed control.

If you already have Makita cordless, go that way. Not having a cord catch and hold you back is well worth it.
what makita needs to do is make a cordless 1/2” shank router for once
40v or 2 18v whatever. I’d buy that sight unseen
I agree. I still use the old Porter cable one speed. Hand held and on the table. Tried and true.

Round over bits.

Not that critical. Pretty much any carbide bit will do what you need. Anything below 1/4" is really unnecessary unless doing very small thin materials.

Flush trim.

My choice is an up cut spiral, but a straight bit will do the job. Definitively do not go down cut. This will force the trimmings into the bearing and give an inaccurate cut.

Multiple bearings also help.

The spiral is a Whiteside.

The ultimate flush trim is a compression bit.

This cuts in both directions. Especially useful when trimming veneered wood and difficult materials like zebrawood.
Excellent for boxes if you want to leave your ends wild and trim perfect.
Zero tear out. Very clean cut.

Also a Whiteside.

Offset kit.

If you want to do offset milling and don't want to pay for the Mobile Solutions kit here is an option.

These are the tasty Amana bits Handy was talking about.
Left is a down cut.
Right is a compression.

These are for a cnc, or could also be used with a fence.

The second time I used it on 1/2" MDF, the bearings spun off the top. Completely came apart
Ya, I can see that happening. There can't be more than 1/16" of shaft holding those bearings on.
2 bearings and a quality bit is the way to go.

This is the one I refenced above.

Also on a 1/4" bit you want to cut as little as possible as a flush trim is done in one pass.
