Default Availability Of 235mm Blades With 3.5mm kerf

Hi all,
I can find 235mm 40T circular saw blades 2.6mm to a 3mm kerf.
Are 235mm 40T blades not configured to a 3.5mm kerf?
If available would like to locate in the UK.

in 5/32" they are.. (3.96/4.0mm) the 235mm (9") is a little tougher...

Freud may be able to help out...

on an off chance are you looking for 253mm blade and no a 235???

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

Sorry. Found one Dewalt 235mm 40T blade, 3.4mm kerf, but it had a 1" bore... Sure you probably have a 30mm bore.

Hi Peter

235mm saw blades are always for use on portable saws, so they won't be available ex-stock with such a wide kerf. you might like to try talking to a reputable saw doctor (or even a manufacturer) rather than to a retailer or the like. In general 250 to 315mm industrial quality blades have a kerf of 3.2 or so WHEN NEW, whilst larger blades such as 350 or 400mm are more likely to have the 3.5mm kerf you require. One excellent British saw maker I'd recommend is Ernest Bennett in Sheffield who are very knowledgeable and will supply standard blades with special tip grinds, wider kerf, etc at minimal extra cost over their standard products - but as an industrial supplier they aren't going to be eBay surplus prices! Another reputable firm (saw maker) a bit nearer to you is NLS (North London Saw) and there also used to be a firm called CRM Saw in Waterlooville, Hampshire (near you?) but I can't find any current web site for them. Failing them why not contact the UK Saw Doctor Association who'd tell you who their nearest member is. Please note, however, that a blade which starts at 3.5mm kerf won't have quite as thick a kerf after it has been sharpened because the tips all have edge relief ground onto them to reduce the tendency to scorch in cut. Grinding cuts into this relief so every time you grind a carbide blade the kerf gets slightly narrower.

Regards

Phil

Hi Mike

Any saw doctor over here will center a blade and bore-out for you for about £6 or £7. Some will do it while you wait
