I just did mine with a spade/butterfly bit. Exact size and clean hole.

 

Moose...Only hole saw I've seen is the big ones that you use to drill a clean hole for a dryer, say 3 1/2" bore? I've seen smaller ones for drilling through wood for electrical, but they're huge 1/2" chuck angle drills.....not sure what you mean.

I've got both the thumb warmers and the grip warmers in my lap at the moment. Timely info.

 

they look just like a big hole sawy, just mini, like these:

700 Sportsman hit it on the head. There are smaller bores. I generally used them installing locksets in doors. The bi-metal hole saws will even cut through a steel door with patience. A spade bit can be bad in thin material and make a rounded triangular hole. A forstner bit would be a better second choice over the spade bit. Both the hole saw and forstner are designed to cut sharp clean holes.

 

Got cha...Didn't realize they made them that small.

 

Not to change the subject too much, but I've got a nice set of heated grips waiting to be installed. Wish they were installed today boy,.......cold. They're Moose grips that have a little rocker switch (round). Also have a stick-on thumb warmer for the throttle; however the thumb switch, which is also made by Moose, is square and looks like something from the 1940s. I'm wondering if anybody knows of any rocker switches that I could mount in the plastic that match, and may be a bit higher quality. The round one is OK, but still on the cheap side. Any ideas....or anybody else swap theirs out?

 

just make sure they will handle the power that goes thru them w/out burnig then out. you could go to an auto parts store and get a good quailty one that might be what your looking for. just a thought

 

X3 works for me to!!!

 

Huhhh??

 

just a thought but I would go to the local boat dealer and get marine grade switches. they are more $$ but will hold up in the weather where automotive will not. The Bass and Saltwater boat places sell high amp/volt switches for all sorts of applications. Again they will cost more but they should last the life of the ATV.
