Rillfit Groover - What am I doing wrong?

I have a Rillfit 4. I've only used it once in the past to take half of each center lug out of a set of Iroks. Back then it was super easy. It took about 30 mins per tire and it cut through like a hot knife through butter on setting 1. I think I used 2 blades. That was about 4-5 years ago.

Now I am trying to cut up a set of boggers and it is fighting me every step of the way. Settings 1 & 2 aren't hot enough and settings 3 and 4 melt the blade in 1 second flat. I've tried pre-heating a lug with a heat gun with no discernible difference. Small blades, large blades, none seem to want to cut right, all require me to really push though when I know that the heat should be pulling itself through. Of course, pushing so hard often results in shooting out the back side of the lug and hitting the next lug with a hot blade, bending and ruining it. It took about 6 hours yesterday to do 1/8 of a tire, experimenting with different techniques and finding none that worked. Anyone got any advice?

Pics of the head of the groover and the two retention blocks... the blade isn't backwards is it?

Blade is not backwards. I can't easily get those pics right now. This is exactly what the groover looks like though and the blocks appear to be identical.

I have one myself. I've noticed that if I cut more than a half inch deep mine does the same thing. And just for a moment I have loaded a blade backwards and can tell your from experiance that just wont work :****:

Definitely works better the shallower I cut.

I thought the preferred method was with a chainsaw

I've already had one trip to the ER while trying to accomplish this job, don't need another.

Just realized I posted this in the wrong section. Can a mod please move it to tech?

Anyway, both these methods seem infinitely faster than my $400 groover.

Done

Thank you.

A deeper blade would probably help you out in this situation. Then you could use a higher heat setting. Some tires are just a pain in the ass. I find it helpful to have other things going on, and hitting the groover real hard for 3 - 5 minutes or so. It helps with my patience anyway.

a $40 oscillating cutter from HF works good for whole tread removal. Just sharpen the teeth off of the blade it comes with.

So like a flush cutter blade sharpened to a knife point?

I had this same thing happen to me. Did three tires in about 2 hours apiece. Then the last tool about six hours and 20 blades. I think the head was worn out on the one I used.

My question is, How did he sipe those boggers on that vieo?

They came from the factory that way

yep, it'll lop the treads right off.

Pretty much sucks for trying to cut the tire any other way except whole tread removal, but works great for that.



I cut these SX with a wood chisel and a bottle torch. Trick that that is getting your heat right so it cuts but doesn't burn/smoke. I found that I could normally cut 2-3 1/2 tread before re-heating.
I split the blocks first, then lopped the block off.



On the boggers I used the osciallating tool to cut tread

Got me the cheap HF multifunction tool with some blades and a good wood chisel today, will report back. Thanks.

I am wanting to grove some tires as well. been doing some research too saw this video looks pretty fast
