18 or 20v right angle torque minimums?

Hello,

I looked at the specs of the winchrite, and it reads 110ft/lbs. People on other threads have used the large Milwaukee unit, however that seems like overkill to me. There are a number of smaller right angle cordless units on the market that have excess of the winchrite torque specs and are a lot less weight than the Milwaukee (ie. ryobi, dewalt, etc). These guys are way less expensive. Here's a link to just one of the reviews I read:

https://www.hottenreviews.com/right-...ordless-drill/

So, my question is has anyone used one these, and thoughts on what would be the range of torques required ( or desired )...

Thanks

The mass and length of the Milwaukee 28v makes it much easier to handle the torque on a winch. The shorter, lighter machines will take a lot more muscle to run. They might be easier to move around, but on the winch , you'll wish you had the milwaukee.

For putting a big man up the mast go with the Milwaukee

Re: 18 or 20v right angle torque minimums?

We went through this exercise last year... We ended up choosing the Ultimate Cranker package as the best value for our needs.

Why buy that when I already have the DeWalt 20 Volt tools onboard? Because they don't have enough torque to perform the job in question.

Short version of details:

As you know, torque is measured in force applied at a distance from center of rotation. [e.g., lets use inch-pounds in this case. in-lbs]

Lets assume the author of the article you linked meant inch-pounds because as written, pounds make no sense as pounds are not a measure of torque. [foot-pounds? inch-pounds? etc...]

From the article, the highest torque drill motor tested was 360 in-lbs [Remember we are taking this unconfirmed value from the article, and assuming the author meant in-lbs].

360 in-lbs/12 in = 30 ft-lbs max. So, if you never need to apply more than 30 pounds of force at the end of a 12" long winch handle to accomplish what you want to do, this drill motor is marginal at best.

[Besides, by the time you spend US$90 on the stainless steel winch adapter, you are almost halfway to the cost of the way superior Milwaukee package linked above... ]

The Milwaukee drill motor cranks out 3x that much torque capacity: 1081 in-lbs [90 ft-lbs] i.e., equivalent to 90 lbs of force at the end of your 12" winch handle cranking the winch...

The Winchrite comes in at 1150 in-lbs [96ft-lbs].

Why did we choose the Milwaukee drill over the Winchrite?

For one, it was about 25% cheaper at the time.

And the drill is also a drill- with interchangable batteries [We have 2; The Winchrite has to be plugged in to charge the unit possibly part way through a day's work... And what do we do when the battery needs replacing and they cannot ship us a Lithium battery via air because of our remote location?]

If you are interested in reading more details about our reasoning, see the portion of our boat upgrades post from last year [about halfway down that page...] that discusses why we chose the Ultimate Cranker as our solution.

It is a beast by-the-way... It is also our back-up in case the electric motor on our windlass ever fails...

In hopes this helps explain why the smaller drill motors will not be adequate for larger winch loads...

Cheers! Bill

PS: If you do go with the Milwaukee, be sure to get the newer M28 28 volt lithium batteries [which superceed the V28...] and get the stainless steel winch adapter that replaces the chuck instead of a winch bit you place in the chuck. Why? For two reasons: It makes a shorter form factor to the winch, and it won't unscrew under load in reverse like a chuck can...

Re: 18 or 20v right angle torque minimums?

We've had the Winchrite for 2 seasons now and are very happy with the purchase. We got it from Defender when there was a rebate, so we only paid $600, but is still seemed pricey.

The Winchrite has a lower (ie., better) profile that the other options and is a 2-speed device. It comes with both 12V and 110V chargers. We've never had it run down and have checked to see how quickly it would charge on 12V, should we be on the water if it did run down. After using it to hoist our full-length batten main a few times and after using it with our single line reefing, it still had plenty of power, but we put in on the 12V charger and it was remarkably quick to full charge. Likewise on the 110V charger at home.

My bottom line is that the Winchrite is a well-engineered, well-built product for the intended application. Modified drills are awkward by comparison. Yes, I would recommend it to a friend and no, I don't have any interest in the manufacturer or Defender.

P.S. When you hit a hard stop, like when the main is fully up, you will feel the torque--just a cautionary note for the sailing spouse with a wrist injury.
