what is the hardness rating (A)
707090
I don't know what the rating is but they didn't last long for my son. Maybe 3 weeks.

I am not understanding the nature of your question fully. At any rate I will attempt to answer to the best of my ability. It is a lil trick applying the wheels but you can find a good youtube video to assist you. That is what my son did to put the wheels on himself and he was 13 at the time. I hope I answered your question to satisfaction. All the best to you and Happy Safe Ripstik riding.

I would think so since on the Knoop hardness scale glass&ceramic; is 400-550, porcelain floor tile is 500-650, and granite is 550-650, tungsten carbide is 2000 and diamond 7000. diamondsure.com/materials.shtmlHope this helps.Charlie

Many differences - weight of A-1 is 30% more than Spyderco Schempp Rock and blade material in A-1 is laminated VG10 vs all VG10 for Spyderco. Blade thickness for A-1 is 1/4-inch, which is 2X thickness of Spyderco Schempp Rock blade. The A-1 blade is convex grind, which provides additional backbone to the cutting edge than the flat grind of the Spyderco. All in all, the A-1 blade would likely hold up to a lot more hard use than the Spyderco.

I'm not sure what grade they are, but they are the best drill bits that I have ever bought. They work very well, and stay sharp, even after using. I hope this helps.

I believe that rating only applies to the data lines. if you look at the spec page on apc you will find this rating comes directly after data line protection and data lines protected.

I would say it is an 8th of an in. But very strong.. I am very satisfied with the product.

Granite has a hardness of 6-7 and the carbide steel point has a hardness of of 8.5 so the point should win out. It depends on how detailed a design you are trying to do since the tip will round some in use. There is the heavy duty #9929 point as an alternative.

They don't rate the durometer rating on their product. However, after using it against other silicone products that do have ratings, I would say it is around a 20A shore hardness. It is very flexible, deals with undercuts well though you need to be careful with regards to tearing. It is a great beginner silicone until you "get the feel" for casting and start using specialized silicone for different project needs.

I found a chart by searching 42hs4013a4, it seems to indicate 5mm, with a tolerance of 0 to -0.012.

The core of the blade is VG-10 hardened to Rc 60-61 with a softer outer layer of stainless. In other words a clad knife . This allows the cutting edge to be harder but the over all knife to be tougher and not break or chip as easily .

My sister and I installed it in about 2 hours. I'd say it's 4 or 5 on the hardness scale.

There are several out there. There is one from (tiny gadget) that is 0.4mm with a 9h hardness rating that is equal to the one that is in the bundle pack. And its a great price as well.

i dont know what ANSI rated is but i used them to load cement trucks and the cement ruined the lens .

Im not sure what its rated but at 185 it was good for about a month and then the base split like crazy and the shaft went completely through it. DO NOT BUY IT!!!!

Don't know grade, but it is definitely a good quality and not cheaply made.

High carbon steel with a Rockwell hardness of 57/59, hope it helps. Chef Ryan

Hard rigid plastic which can't bend, dent or rust like the aluminum ones. Excellent quality for an excellent product!!
