Whats everybody,s choice in cut off wheels and there source for them

A couple of tricks I have learned over the years to save your 3'' roloc grinding discs.. I use a cutoff wheel behind my roloc grinding disc as a backing disc to keep the grinding disc from flexing and wearing out. I also save used cutoff disks at different sizes, this helps sometimes getting into tight spaces. I also cut down my grinding discs 1/4''-1/2" or so at a time, as they wear out(they usually only wear on the outer edge). As stated allready I try to keep the rpm's down, when I weld (sheet metal) I try to keep the weld build up as low as possible, saving time and money.

 

From a previous HF thread:

Re: OK: How About a POSITIVE HARBOR FREIGHT Thread???

Cut off wheels: BEWARE! Too many guys on here saying "Never had a cut off wheel explode ..." That's like saying "Never had a fatal head-on." Google the carnage.

"Similar thing happened to a guy at my old job. Blew through a face shield and sliced open his neck just missing the jugular."

"The cutting tool, consisting of a bonded abrasive disc, failed prematurely during the routine sectioning of a steel member. The operator was injured as a result. ****ysis indicated an improper mixture of the organic cons***uents comprising the wheel bonding material. Instead of the uniform wear anticipated under normal cutting conditions, the improper mixture resulted in a degradation of the wheel’s mechanical properties, and catastrophic brittle fracture."

Anyone who is awake knows the Chinese sacrifice quality without regard for your life. IF you make it to the emergency room, you'll pay 100 times the savings you got buying cheap cut off wheels.

 

I have used the ones that lowes and home depot have. They ain't worth ****. i don't use those from H/F either. They are ****.

I really like Pferd. It's a good quality German product. With my Ingersoll shielded cutoff tool, Pferd wheels perform extremely well. They have very good cutting ability with low dust.
Put a HF cutoff wheel in the same tool?? Longevity is WAY down. Cutting speed ability is slowed combined with faster wear. Then shutdown time for needing to replace them more often.
So do you REALLY save money by using cheap abrasive products? Not in my experience.
Chop saw blades are another expendible that will surprise you. Two blades a day on a few jobs vs. a blade for four days on many heavy and light jobs.
Norton Norzon III railcut blades are more than worth the expense due to durability and cutting ability. They're made to endure a plunge cut thru a train rail and not glaze, gum, ball, or shatter.

 

SAIT Brand 4 1/2" x .045
return them to work once i'm done
shop foreman bought hilti brand onc ebut they don't seem to last as long

 

We started using these a few months ago at the shop. I am very happy/impressed with them.

 

Good choice's and prices from you fellas. Keep this thread going.

 

great thread,, thanks all ,Im with Thaugen on his view on the dangers using the cheaper Chinese wheels not to mention they wear so quick and fill the air with dust from whatever there made from..,,Im wanting to give the Walter zips a try,I only found one distributor "Etools" is that a good source?

 

The HF ones will wear down fast on sheetmetal cuts, for some reason, they're better for cutting through bolts and the like. At least that's what I've noticed, if I were cutting sheet frequently, I'd buy something better quality. But it could just be using the HF grinder to spin them on, too.
