Topic tags/keywords: bosch gcm12sd

I bought a Bosch GCM12SD last weekend after a couple of weeks research on trying to find a miter saw that didn’t need clearance behind it for the guide rails to try and save some room in my car garage shop. I finally got it out of the box and setup last night, blade is flat and perpendicular to the bed and rails so I made a few test cuts with it last night. Here are the results:

With these being less than ideal I checked the runout on the blade, it’s anywhere from +.009 to -.004. Like I said I checked the blade with a straight edge and it looks fine. I’ve heard that 12” saws have more blade wobble but is this acceptable? I’m not sure if I should get a new blade and re-test or take the saw back.

I would try a different blade for sure. Its the easiest variable to eliminate.

It looks good to me.Esp if your using the blade that came with the saw.
Your technique and material will affect cuts just as much as the blade.
Run out is irrelevant unless your trying to get a perfect saw kerf that matches the blade width.
I have a forest chop master blade on mine since I cut solid wood.

I have the same saw Bosch glide it’s a good saw,for the price.

Wow! So, we’re talking about a nominal difference of .005? I have that same saw, and I’ve never thought of it in that type of accuracy. It crosscuts a 12” board, and does a helluva job on the bigger crown mouldings. Do I still have to caulk and wood-fill? Sure. Sometimes.

C’mon guys! This isn’t precision-machining! We’re talking about wood! Which is, for the most part, a still-living, breathing, MOVING entity….even after it’s cut, dried and put on a retail shelf.

Have your say...
