Naomi Posted July 13, 2021 Report Share Posted July 13, 2021 Hi everyone. I got a Freud blade for my 10” contractor saw. It’s a Bosch GTS 10XC. The problem is that the arbour hole is smaller on the Freud blade than on the factory blade that Bosch puts out and therefore doesn’t sit well with the arbour nut (not sure if that’s the term). Does anyone have experience with getting a replacement arbour nut to use with Freud blades or have I just selected the wrong arbour hole and need a new blade?

Tpt life Posted July 13, 2021 Report Share Posted July 13, 2021 Just confirming, there should be a washer style clamp under the arbor nut. In other words, two things go outside the blade. Have you installed that correctly and still have issues? 1 Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted July 13, 2021 Report Share Posted July 13, 2021 Maybe I misunderstand your description...if the hole is smaller, how does it fit onto the arbor? Sorry, I am not familiar with that particular saw. Quote Link to comment Share on other sites More sharing options...
Tpt life Posted July 13, 2021 Report Share Posted July 13, 2021 Good catch Ross, I misread that. I don’t see anything in the manual other than a lot of cautionary language about using blades approved for the saw. Naomi, can you please list the blade information? What Freud blade?

Chestnut Posted July 13, 2021 Report Share Posted July 13, 2021 It looks like the saw requires a blade with a 30mm Arbor for the flange to mount properly. Make sure you check the arbor size before purchase. I know based on where you live you are likely having to order from another country. Standards for these things are different based on the region you live in. It appears available arbor sizes are 5/8" (US standard), 20mm, 1", and 30 mm. You may have ended up with a 1" arbor which is smaller than a 30mm. I'm guessing the arbor is 30mm and it might be best to check the owners manual for your specific saw or measure the arbor size for the blade that came off of it. 2 Quote Link to comment Share on other sites More sharing options...

Sorry, I am not familiar with that particular saw. It appears the EU saws have a flange that fits on a ~14mm shaft that holds a balde with a much larger arbor. See picture below. 2 Quote Link to comment Share on other sites More sharing options...
Immortan D Posted July 13, 2021 Report Share Posted July 13, 2021 AFAIK the hole on the blade should be 30mm so it will fit in the bushing included with the table saw. Here's a pic of such bushing from my Bosch saw (European version): 1 Quote Link to comment Share on other sites More sharing options...
gee-dub Posted July 13, 2021 Report Share Posted July 13, 2021 The location is Israel. I wonder if the blade is made for saws sold in that part of the world or vice versa? I tend to be pretty western-world-centric in my thinking sometimes. Forum members in Spain or Australia find slightly different tools on the shelves.

Naomi Posted July 14, 2021 Author Report Share Posted July 14, 2021 I think we mostly have whatever the Europeans have. We also run on 220 electricity. I get a lot of tools from EU and UK Quote Link to comment Share on other sites More sharing options...

Naomi Posted July 14, 2021 Author Report Share Posted July 14, 2021 Here’s a photo of the same part in the factory blade. The problem with my new blade is that the hole is too small for that part to sit on Quote Link to comment Share on other sites More sharing options...

See picture below. That’s the weird thing. The arbor fits the blade but that other piece that I don’t know what it’s called- it’s the right circle in your photo- the new blade can’t ride on it Quote Link to comment Share on other sites More sharing options...

It’s an American bought blade. It’s a Diablo ultra finish with 80 teeth. It fits on the arbor but not on the nut thing that sits on the arbor. Flange?

The problem with my new blade is that the hole is too small for that part to sit on So if this is the blade that came off the saw the numbers provide you the dimensions for a new blade. It's 254 mm in diameter, it's kerf or the cut width is 2.6mm and the arbor hole is 30mm. You might need to buy blades from a UK store. Almost all American saws use a 5/8" arbor hole.

Naomi Posted July 14, 2021 Author Report Share Posted July 14, 2021 Oh man! I took out the manual and the part that I thought I could just swap out is called a mounting flange. I’ll see if I can get one of those but if not I’ll gift the blade to someone. Quote Link to comment Share on other sites More sharing options...
Immortan D Posted July 14, 2021 Report Share Posted July 14, 2021 You can ask a machinist to enlarge the arbor hole to 30mm. Quote Link to comment Share on other sites More sharing options...
Naomi Posted January 18, 2023 Author Report Share Posted January 18, 2023 On the offchance it's not too old to revive this thread, I am wondering if simply purchasing this flange for the American model would ensure the ability to use blades with a 5/8" bore? https://www.ereplacementparts.com/washer-p-200814.html Quote Link to comment Share on other sites More sharing options...
