Cutting a laminate worktop

saxtonblades dont sell via screwfix or toolstation
https://www.saxtonblades.co.uk
you have a 2.5mm Kerf on the blade spec
All i can seem to find is 30mm bore and not the 20mm bore you have , I know you can get a size reduction ring, but not sure for that blade or safety - I would wait for one of the trades to reply

I have used a freud, a lot , expensive , but i also had sharpened - But the price to sharpen is more than a new blade from saxtonblades
But I had 4 different freud blades sharpened so worth it

no, based on link to screwfix - https://www.screwfix.com/p/erbauer-...l+Content&utm_content=TextLink&utm_term=58258
Now seems to have changed to a 160mm Toolstation

your diameter is 190mm and bore size 20mm - Bore is the size of the hole thats fits onto the motor and so needs to be 20m or possibly a reducing ring from 30-20mm BUT as mentioned not sure about safety on a circular saw
and anything over 190mm will /should NOT fit into the blade cover
A 165m blade I dont know how that will perform, possibly the riving knife would not be effective, hence the wood is gripping the blade and stopping it , possibly - also the smaller blade may turn faster , with less torque or slower as a smaller diameter and maybe too fast, and burning , too slow and catching
Also a safety issue using a much smaller blade
190 - 160 =30mm (15mm away from the blade safety ring ), and so dust/debris will not catch in the guard, and may be thrown out
I really dont know
But sure others more experienced will advise

Sorry, edited it as I posted the wrong link!

I'm thinking I don't necessarily need it to be 190mm diameter - it can be smaller.

I just want something that will cut through a laminate worktop reasonably neatly!

I would get this blade but they are showing 24-48 hours wait at all the nearby stores.

Who knew that getting a circular saw blade would be so difficult?!

Getting a blade is easy - if you are prepared to accept carp. Getting a decent quality blade is worth the wait. TBH I can rarely get the blades I need over the counter without paying a premium, if at all. As to SFX and TS their service and stockhoolding have.gone to hell in a basket since last summer

Saxton are a direct sales organisation - you need to buy them either direct or via Ebay or on Amazon

Just looked on Amazon - they sell the Saxton TCT19080T saw blade - 190mm diameter x 30mm bore x 80 teeth ATB - comes with 16, 20 and 25mm blade washers (these allow the saw blade to be used on saws with different sizes of arbor) - £11.49.

Alternatively Amazon also sell the Trend CraftPro CSB/19060TC saw blade - 190mm diameter x 30mm bore x 60 teeth ATB - and whilst it doesn't state it the CraftPro blades come with blade washers, Although I don't know what sizes. Price £15.00

As to blade sizes and safety, the rule of thumb (as accepted by the HSE on building sites and in factories) is that a saw blade must not be less than 60%, of the design diameter of the saw - which in the case of a 190mm saw gives a minimum size of 115mm, although I doubt I'd want to go that small. Blade washers are definitely a safer option

I've used Trend cp blades as replacement blades without a problem- I'd say they are good value.

as for the blade overheating I'm surprised that if the blade is overheating then it is binding so the workpiece isn't properly supported in all directions including laterally. I'd be expecting the saw to stall rather than the blade overheat.
in my experience a fine cut (lots of teeth) blade will smoke if you are asking it cut to fast - mainly 'cause the gullet is filling up with the cuttings (sawdust).

is the riving knife fixed or sprung? If it's sprung is it extending fully behind the blade? That can cause the the blade to bind and heat up.

Cheers, I've ordered the Saxton from Amazon and I will divert my attention to gardening on this beautiful day!
