Carbide teeth grinding questions

[AAASTUMPSERVICE]

Can anyone tell me what setup works for you when it comes to sharpening carbide stump grinder teeth? I don't mind spending a few extra $$$ to get setup to sharpen my own teeth, I think it will save money down the road.

What type grinder to use?

What diamond wheel works best?

What type of teeth do you have?

I have carlton (diamond style) teeth.

I'm confused. Do you have Sandvik or a 1/2" x 1/2" square shanked tooth?

Wether it's Sandvik or square shanked tooth you'll need a hand grinder with about a 3 1/2" wheel. I prefer the diamond wheel rather than a green wheel. The diamond wheel will last a lot longer than a green wheel. It will most probably be easier to re-sharpen them while they're on the grinder.

Precautions to take to sharpen tungsten carbide teeth

With 300 hours of stump grinding experience since 2003 and currently owning two walk-behind stump grinders, I decided not to try to sharpen teeth. My in-depth study Tok several months and showed that the cutting angle of worn teeth resharpened has less cutting effect. I also learned that the risk of exposure to carcinogens from the fine dust are not worth the cost saved and the equipment cost. One of my stump grinders uses green teeth in the #500 size and the teeth get three rotations, so the use cost is spread thin by making full utilization of the cutting surfaces. I am interested to learn how other folks like the Sanvik teeth and the Vermeer Super teeth. The web site for Leonardi Manufacturing shows some interesting designs in cutter effectiveness. That's my two cents worth.

I just picked up a set of Greenteeth LoPros for our stump grinder... Got the entire set from Bailey's for under $400 shipped. Already have a fairly large job (for us) that we are finishing up, with 6 stumps to grind out (1-40" Oak, 1-30" Pecan, 1-24" Pecan, 1-18" Hickory, and 1- 18" Cedar). It's just my partner and I running our grinder, so I will let you guys know how well they perform.

I put green teeth on my rayco
1625super jr. Work great like the fact that they have three cutting surfaces and easy to change in the field

A good diamond coated bench grinder wheel for the carbide,gets them better than new.

need a decent benchgrinder and steel grinding wheel to get the holder in right shape BEFORE grinding the carbide.

Where did you buy a diamond wheel for your bench grinder? How much was it?

I am with the same thought as "treetopguy" i have been grinding stumps with my own grinder for 12 years now and never sharpened teeth. i allways found it easyer just to put on new teeth. Is the cost difference worth the time saved by just putting on new teeth. I have had veermer 206 and rayco 1625 with greenteeth, and carlton 4012 with a sandvick wheel, and now vermeer 652 with asandvick wheel. my experence by the time i notice that the tooth is damaged or dull there is not much left or worth sharpeing. Can someone post me a pic of what there dull teeth look like and what they look like when there done sharpeng it or a vid of them sharp would be even better. I just got 50 or so new teeth for my stumper wheel wich i will be putting on this weekend. May be i can save myself some time next time.

- i grind about 28 000 to 20 000 inches a year and replace my front lead teeth 3-4 times a season we only have a 9 month season with 490hrs on my machine that is 1.5 yrs old.
- just repacing my side teeth for the frist time i think there is about 25 of them.

any help or questions would be great

Ya I now know its not even worth sharpening teeth or retipping, its easiest and faster to have new teeth to put in. I just sent out a flat rate box full of teeth (30-40) to get retipped. The post office lost my package!!! I guess all those teeth are junk but I was hoping to have them retipped for half the cost of new but since they are Mia I'll just buy new from here on out.

Sandvik teeth are roughly $6-$7 a tooth

I use a green grinding wheel. And a 4 1/2 inch diamond angle grinder. I have a can-du machine, and those teeth will not go on any other machine. If I didn't sharpen my own it would not be very cost effective. I use a cup maske and face shield for protection .

I run a 352 with greenteeth, and sharpen my own. Bought the diamond wheel from green mtg. $175.

I run 3 sets, and after turning & rotating, I resharpen. Works great for me, & I always keep sharp teeth on the machine. I've even taught my daughter how to do the sharpening & I pay her $1 per tooth. I set up a shop vac to catch the grindings as they leave the wheel. I've been doing it this way for about a year now, & I find that I'm buying way fewer teeth. So far I'm happy with it.

Save them grindings and mix them in with the concrete the next time you pour steps, they will wear forever. I worked in a factory that mixed carbide chips with theirs and they looked like new after my tired arse and everybody else walked up and down them for years. Sparkled also when the light caught them, kinda pretty.

Cool idea, thanks fubar. Just so happens I have a brick patio project in the near future. I'll def put the carbide to use.

Yer welcome. I don't know how well it will work with grinding dust, sure won't hurt though. Amish braze chips to the front of buggy horses shoes and wear out fewer shoes. Thats why in Amish country the right lane in the road has a big dip in the middle of it going up hills.
