Is this the correct slot cut bit?

I just want to make sure before I buy it, or if anyone knows of a less expensive one.
$16 for the complete bit.

Item #301 - 1/16" width, 1/4" shank, and cuts 1/2" in to the wood.

Thanks.

Use with T-Molding that has a 3/32" wide spine (including the barbs).

This is taken off t-molding.com's site for a 1/16th cutter!

Depending on your t-molding you should see how wide the spine is!

Sorry, I guess I should of mentioned that yes I am ordering from t-molding.com and have a few free smaples from them at the moment.
Ill probably be using their normal 'ol Black 5/8" or 3/4" with my 5/8 MDF.

I see their 5/8 lists a 3/32 spline, and the 3/4 says 1/16 spline, but I have both in front of me, and they look the same. I also recall hearing people use 1/16 bit for both 5/8 and 3/4, so do you think 1/16 bit will be good?

Just wanted to echo that really. Look up the colours of t-moulding you are intending to use on t-moulding.com as some colours have a different spine width, for example the black pin stripe t-moulding.

You can cut different slot widths with one cutter if you don't want to buy more than one. Cut your t-slot centrally with the smallest cutter and then adjust the height slightly before running the router over both sides of your material. This will give you a slightly wider slot that is still central. You can keep adjusting the height until the achieve the slot width you desire.

Its good practice in general to run your router around both sides of the materail even if you are cutting a 'cutter width' slot.

Check to see if you have a harbor freight store near you. I picked up a slot cutter set for $22.00 after using one of those 20% coupons they have in auto magazines.

Got the one from MLCS, and it works with 5/8 and 3/4 TMolding.

The 3/32nd spline is the one you need, the flat part of the plastic (t-molding) is 3/4 wide.. You can also buy the complete router bit over at www.michiganclassicarcade.com I have two left.

stay away from 3/32! Or use glue on all your grooves like I had to do... 1/16 the way to go.

why?? 3/32nd works.. what happen to yours?

Because you wont probably be perfectly centered when routing so flipping the MDF over will center your groove with a 1/16 bit. That will also make the groove a little bit larger but will still be perfect. You cant do that with 3/32 or then you have eagle eyes to be perfectly centered and not have to route the other side. Fact is, if you search for "t-molding groove too big" or something similar on this forum you will see that lot of people using 3/32 bit had to use glue to make their t-molding stay in the groove. We are far from having to use a rubber hammer to fit in it. It is just easier with a 1/16 bit that is all im saying.

You did use a 3/32 personnaly ? Congrats if you didnt had any problem  I wish I had more experience.
