Torque Test Channel Open End Wrench Testing Part 2

Here's the full thing. Again this is just for reference. Will leave it up to the engineering and production guys to detail how all this works.

Wright Grip baby! I was glad to see the video and see they were still on top, tied with proto for maxing out the rig.

I bought my Wright Grip 2.0 only a couple years ago and dang I wish I'd have known about Wright long ago.

Heck of a deal on Amazon too.
My only gripe is why skip 16mm and 18mm? My honda has 18mm all over. I had to order the two sizes separately to complete the set.

Looking at a mac wrench it hints of forging as can see slight deforming around the large lettering .
I quite agree the design is made be somewhat universal but I can't see major advantage in running one die and adding additional production steps when they got production number limits before die worn out .

I found some close up shots of the MAC RBRT wrenches:





I'm very confident they letters are milled on. They look exactly the same as on my USAG wrenches:

Looks like the letters and numbers are milled on after the forging process. Make sense if they use the same wrench for multiple brands.

 

[AdAstra]

I think that does not look like milling... the sharp corners at the tips of the letters would be very hard to make, without a minuscule endmill smaller than the main track of the numerals... And that would be so much less efficient than just impressing them in during forging.

(Also forging can be multi-hit. They could share many of the same roughing dies and only differ in the final die.)

There used to be a snap-on wall art piece, with all the steps of forging. It clearly shows that the business ends are finals-sized by being "cold broached" after forging. This general step of being cold-worked aslo includes the stamping of the sizes.

The broaching and stamping step needs tooling and setup time that cost money. For cheap tools, they skip the mechanical stamping of sizes. This is why all those cheap impacts are only laser-etched.

Presumably the quality of the broaching tools is up to each end user/brand...and you can cut corners if you wish here. Heat treat is also done at this stage, and again, can be done to spec for each brand.

I have cheap impacts that are stamped, I think. I'd assume lasering would look better. I figure they're probably roll stamped.

 

[F-22]

Sorry, milled or stamped - either way they are made with the exact same procedure as the USAG ones. After thinking about it I also doubt the sharp corners are milled, will look closer when I come home.

My point is that the two wrenches are exactly the same except for the markings, and the markings are made in the same way too.

 

[Andres26tnt]

Overall I think it's safe to say that all these Stanley B&D tools are going to perform very similar. Just wish they offered the same line up in the USA.

Looking at some of my smaller Mac Precision Torque combos, sometimes there will be a small bump on the beam edge around the "MAC" lettering. I assumed that was metal deformation from stamping the Mac name on the wrench later in the manufacturing process.

I think Write Tools read your post! Agreed on being silly for not getting sooner. Not only do they work STUPID good, but they're unbelievably smooth, a pleasure to use, the case is great, and they ooze quality. No doubt Icon is a Best Buy (I have the SAE set), but this is next level stuff and I love the matte finish.
