Dear All,
There are certain tips on the market now that when after installing and I am shaping them the layers fall off. I use a brand new blade. I understand that they say to not generate too much heat while shaping by slowing the lathe down. I also put a fan on the tip. But it still happens from time to time. Should I use one of the auto tip shapers?
Thank you in advance,
Jon

Hi Jon
You will find that layered tips are very sensitive to rpm speed.
 
Not trying to rain on your parade, but just cause its a new blade don't mean its a good one. I used Milwaukee brand for a short period because that's what my local hardware store had, and was having issues getting a good cut. I think a popular brand amongst us is Lenox carbide edge blades, those are some good cutting blades and worth the price. I cut and trim my tips at 800rpm.

The big names in power tools generally don't make their own accessories like utility blades, screwdriver bits, saw blades and ....

40 years ago there was a Co named US Blade. Maybe their still in business but don't have a website... Old school.
I'm sure Co's like this Private Label bla"des for everybody.

Lenox may not make their blades but at least they know exactly what they want.

Maybe Milwaukee and that ilk know what they want, but that might only be "we want something sharp" with no concern about tool life. Heck, who's gonna spend the money on a study when everyone knows blades are expendable. These type guys buy cheap and sell high.

Does anyone know that Panasonic supplies circular saw blades to Hilti and Greenlee.
