43-Pc Milwaukee Shockwave 3/8" SAE & Metric Socket Set + 120-Pc Screw Driver Bit Set Expired

To bad no packout case.

But what are the sockets made out of? Cr-v or cr-mo? they just say forged steel as the material....

Does it really matter? Good impact sockets can be made out of either material, just depends on how the manufacturer treats it.

Yeah it matters. Ones a deal and the other isn't.

These are high quality sockets, I wouldn't worry about which alloy they are.

Chromium-Molybdenum or Chromium-Vanadium Steel [tekton.com]

"Chromium-molybdenum and chromium-vanadium produced with equal care and hardened to similar levels have highly similar mechanical properties. In fact, they are almost chemically identical, the main difference being far less than 0.5% by weight in the form of molybdenum or vanadium. Therefore, we cannot say that either chromium-molybdenum or chromium-vanadium is better. Either Cr-Mo or Cr-V is an excellent choice for all normal uses of wrenches, hand-driven sockets, impact sockets, ratchets, and other similar tools. The metallurgical difference between Cr-Mo and Cr-V is insignificant in these applications. Instead, the consistency of the material, the tool geometry, the hardness to which it is heated, and the design and implementation of the manufacturing process control the differences in hand tool quality."

If we're just quoting tool companies

"Chromium-MolybdenumCr-Mo

Cr-Mo: Chromium-Molybdenum alloy steel, also known as chrome-moly or cro-moly, has superior impact resistance than Cr-V, a property that makes it an ideal material for impact sockets, high torque screwdrivers, rachet head components, breaker bar heads and more. The addition of molybdenum gives this alloy the ability to absorb percussive impact better than Cr-V; it also outperforms Cr-V in strength and toughness, but it is more expensive, which is why is reserved for impact rated and high-end tools."

And it's true, cr-mo is much less brittle. also focus on cr-mo being more expensive. the difference in an OK deal vs a slickdeal.

You can't make blanket statements about one alloy being better than another for a tool without considering the processes that each company employs in manufacturing. You need to look at the quality, performance, and longevity of the tools before just writing them off because of a potentially small difference in alloying.

Are there known problems with these sockets or is this just much ado about nothing?

VIM makes a lot of matco stuff so I'd say it's a reputable account. It's not just a generic brand. Matco's impact sockets are also largely sunex cr-mo.

It's not a potentially small difference, it is a difference. And there is a price-point reflection based on that difference. To fully evaluate the deal you need to know the material is, not just the brand name. You said these are high quality, is that personal experience or just Milwaukee fan-stanning?

To fully evaluate the deal you need to know the quality and performance of the product, regardless of which specific alloy they used. These sockets are highly reviewed with nary a negative comment about them. If you allege that they aren't high quality, upon what is that opinion based?

Check out this video to see how they've worked and held up in a repair shop after a couple years of use: https://youtu.be/MJ18e0VIxAE?t=285

So you don't own them, you can't answer my question, and you're just a Milwaukee fanboy. Completely unhelpful.

I already had impact sockets before these came out, so no need to buy them and I barely own any red tools compared to all the other colors in my shop. But that's neither here nor there. Do you have any evidence to counter the overwhelmingly positive reviews of these sockets?

Sometimes Cr-Mo tools cost more than Cr-V tools and tool users want to know the reason.

Well, at least you're honest. Solely evaluating the logical arguments made, you're asserting that these bits are "high quality" and you state that the metrics for quality lie in "quality, performance, and longevity", which would take a fair amount of testing to obtain that kind of data, of which you have none because you haven't even touched said product. The only evidence you provide, is secondhand or basically hearsay aka reviews. A user is not required to test for "quality, performance, and longevity" before leaving a positive review. The video link you provide allegedly show that the bits are still in working condition after extensive use but does not provide a comparison to bits made of Cr-Mo instead. And then finally, you place the burden of proof on him to disprove your own claim that these bits are good quality, despite the fact that neither of you own said bits. However, since it was your own assertion to begin with, the burden of proof lies with you. And offering weak evidence does not excuse you from that, unfortunately.

He doesn't assert that these bits "are bad" but he does claim that when Cr-Mo is a more expensive alloy. And this is alluded to in the paragraph that followed the paragraph you quoted from tekton [tekton.com]:

And this would certainly affect its market value, which is part of the core requirements to determine if a "deal" is "slick", the whole premise of this website.

Me: I Don't neeeeeeeeeed this!!!!!!!!

Also me: Ok fine, this is the last tool purchase for the year
