Works great
Needed to make a new fence for my half lab jig. Just ran the saw blade down the line of the groove and ran the slot across the tTbit and my T bolts fit perfect

Sharp smooth cut. Be sure to use a straight bit to make the channel first. I cut the channel on a table router, then use a hand held router with the t slot bit. The neck of the bit acts like a bushing so no complicated set up needed once you cut the channel where you want. Pay up for quality.

Quality bit as I would expect from rockler, however you get what you pay for, it's about double the cost of others however I need to use it quite a bit for upcoming projects.

To create T-Slot hold downs for my jigs. I questioned whether this bit, which only cuts the base slot, or the Freud which cuts both the vertical and horz. cuts. I purchased this one as well as a 3/8" straight bit because I was concerned with too much waste material being generated. This will be safer.

Does this bit provide a T-Slot compatible with 1/4" (1/4-20) T-Bolt? Is anyone using 1/4-20 hardware with this T-slot? Thanks for your help!
Brian on Jan 16, 2016
BEST ANSWER: It is sized perfectly for a 5/16 T-bolt. The first cut is a 3/8 inch slot cut with a dado blade or straight cut router bit. This groove is followed by the T-slot bit which cuts a 5/8 inch slot in which the T-bold bottom plate slides.
The T-bolt bottom plates aligns with the length parallel to the slot. Both the 1/4 inch and 5/16 T-bolts have the same width bottom plates..so it doesn't make any difference which of these two bolts are used as far as the bottom slot fit is concerned. Of course the 5/16 bolt fits the 3/8 groove with on 1/32 inch clearance on each edge and hence is more stable when sliding. The 1/4 inch bolt has 1/16 inch clearance on each edge so there is a little "slop" here. However it the bolt is intended to remain fairly stationary as with a hold down it shouldn't make a difference.
Is this bit is made to cut the slot so the Rockler T Track can then fit into?
A shopper on Aug 26, 2015
BEST ANSWER: no, this is used to cut a t-slot into wood. A separate metal or aluminum track is not used in such applications.
why am I having trouble cutting a T-Slot in plywood? The bit jumps and gouges and even resets the bit in a different position.
John J on Jul 25, 2016
BEST ANSWER: I have only used it in plywood, and it cut really well. Be sure and follow instructions and cut a slot before using the T-slot cutter.
This cutter requires a 3/8" groove, but the groove in the t-slot of my Rockler router fence is 5/16". Why does this bit require a wider groove?
David K on Feb 21, 2016
BEST ANSWER: The rockler T track actually is 3/8's its cut to except 1/4 and 5/16th t bolts. Here is a link to the T Track specification. http://go.rockler.com/tech/RTD10000592AA.pdf hope this helps.
what is the overall length of this bit? thank you
