i have to small torque wrenches one was able to take lug nuts off a truck. this is amazeing to me
Exactly. I haven't quite figured out why alkalines are called 1.5v and under a load don't keep that voltage and Eneloops are 1.4V off the charger and are called 1.2v which under a light load is mostly depleted. Under no load 3.6V is nowhere near full.I think he is saying that they are inconsistent. On one set of battery packs they are using minimal voltage, and the other battery packs, maximal voltage.
If they are 20V or 12V or 60V they will likely be around for a long time and they use quality cells so you should get many years. I've used my PC and B&D tools for the last 5 years and I bought the tools and batteries used and so far only 1 battery has issues and it was weak to begin with the others work pretty well but I'm sure they have lost some capacity. One word of advice is when you check the batteries and they are on 1 bar swap them out if you can instead of running them down to 1 flashing bar. I always recharge mine after use if them drop one bar as you don't know if it has only about 35% left or 67% left with 3 bars.I only hope my DeWalt liIon packs hold up for a while. Few things as annoying as pulling out the drill after a few months to find the battery packs are all dead and the manufacturer no longer makes them.
It is insane how often DW and MW and a half dozen other cordless tool makers come out with new models of the same tool these days. I have a DW impact that has a slide selector with 3 positions probably the same model as yours and now tool makers and going from the slider to push button electronics with other features like auto stop to not overtighten bolts/screws or something of that nature. I'm not entirely sold on push button switches on rough service tools as I've dropped some of mine even breaking the case of my PC impact, luckily I found a brand new replacement shell/case for under $20 and replaced it but months later dropped it again and cracked it in the same place but luckily not broke it.Yes a weird one with voltages , as we all know dewalt is 18v and 54v for flexvolt, US is 20v and 60v. Marketing or rules /regs or what ever reasons (probably EU regs) that are same.
Well gone and done it 🤦🏻♂️ Last Milwaukee m12 for a while, trying the hydraulic impact out. Although it’s 50nm ish, is performs a a little slower on coaching screws that you would use 20v tools for anyway. But the regular impact 150nm might be 8s, the 50nm 10s . But much quieter, however more vibrations (on those application anyway, which are not right for m12). More to see if can cope above what they are meant for.
So now 3/8 impact
3/8 ratchet 75nm
1/4 50nm with hydraulic.
Less power is better for my work uses and 50nm is a lot anyway on 1/4 drive .
My 18v impact DW 1/4” drive is 205nm on mode 3 and a beast! Can snap the Milwaukee adapters to 1/2” if hard on it! Now and then I use mode 2 which is 150nm, but the mostly on mode 1 which is around 6-8nm. Perfect for m6 bolts! This Milwaukee will go into my other tool bag for smaller jobs . All fun and will see next week how it performs.
And I see mostly Millwalkee tools used by the industry.
In my even more informal survey of industry, Milwaukee seems to have a better following as well. I imagine this has something to do with the dizzying array of specialized tools they make that you're not going to find on the shelves of a home improvement center.I often see Dewalt used by the mechanics who keep the giant Tonka toys running though.
Very interesting as always, find it fascinating with bridges/roads as I’m totally ignorant to all the details.In my line of work we use precise amounts of tension and power tools are only for saving labor. Bolts are fastened to tens of thousands of pounds of pressure, yet over tightening can lead to stretched bolts, which can result in less tension clampage between the two items fastened together. And wax is used to lubricate bolts with predictable results. It has been proven over the decades that fastening dry bolts or using more slippery lubes results in unpredictable tensions between objects.
One example is fastening 2" (50mm) bolts that are 72" (nearly 2m) long embedded in concrete. A traffic signal pole is fastened to the bolt(s) using a cordless tool to get the initial "snug" of about 180 foot pounds. Then a special tool is used to achieve the 25,550 foot pounds of torgue required. The tool has to be calibrated each time it is used and then a dial torque wrench (also calibrated each time used) is used to confirm the torgue. The tension achieved is in the millions of pounds to ensure wind forces from a hurricane do not cause failure of the bolts.
Bridges on the other hand are similar but use hundreds to thousands of bolts tensioned to specific criteria. Guardrail is designed to act as a rubber band effect to corral a vehicle that hits it with predictable forces. Bolts play a large part in that. So again, in both cases the cordless tool is used to snug them and torque wrench used to ensure accurate tensions.
Breaker bars are usually required to break the bolts loose then removed via cordless tools. A volt or two does not really matter. It's run time that matters more than anything. And I see mostly Millwalkee tools used by the industry. Probably because they cost a little less than Dewalt.
