Cordless Drill Minimum Torques

[CoyoteLL]

I have an application where we are needing a low torque with little variation to install some blind, removable fasteners.

Does anyone have any info on minimum torque available in the brand name lines of cordless drills? I looked on Craftsman's webste for manual specs and even a place I could email technical questions, but cannot find what I am looking for.

If torque is the critical factor, consider a small cordless screwdriver or a variable speed drill.

Can it be done with a regular, old-fashioned screw driver?

The drywall specific screwdrivers are better regulated.
They have to drive the screw but not tear the paper.

That is what I was curious about. Need to be able to install 175 fasteners to a torque of 5-10 in-lbs right hand rotation. And then be able to remove them with any amount of torque.

Regular hand driver won't work as we need to do this over 5000 times!

What about an air screwdriver? http://www.northerntool.com/shop/to...cm_pla=Google&cm_ite=https://www.google.com/& Torque could be varied by regulating input air pressure.

Actually, if you can do air, I've got an Ingersoll Rand air screwdriver that is torque limiting. It has an adjustable clutch that is designed to be set to a specific torque, and then the switch is controlled by pushing the bit into the screw.

Most cordless drill have a torque limiting clutch but I have never seen a spec for what the torque is.

Look into the Milwaukee M12 screw driver. It has a torque limiting clutch and the speed is easier to control than the drills. I traded a couple to a fellow who was building RC cars with his kids and he wanted the M12 so he could set it and not have the kids strip out screws.

Milwaukee also has a tech line/email where you could get the min/max info.

You are going to need a low speed driver and you'll need to watch the operators so they don't wind up the drive motor and rely on the clutch. That will get the clutch hot and probably affect the torque values.

I have several cordless drills that the clutch seems to work well, but I just can't find any specs showing minumum torque values!

Have sent a note off to Milwaukee. I see they have posted a range of 10-140 in-lbs on a corded Screwdriver. I have asked them what the minimum torque for the M12 line is and if it is consistent.

We shall see! Thanks for y'all help.

Op any drill with a variable clutch with do that simply hook it to your torque wrench to st it to the right torque

 

[Boomer343]

delorian for the OP I doubt he has an accurate way to measure 5 to 10 inch pounds.

At that low of torque rotating mass of the drill makes it tough to get that low of torque.

Dedicated low torque powered screw drivers use low speed, low rotating mass so the cluch can do it's job repeatedly.

Why the secretiveness Coyote? What's the 5000 screw application...maybe we have ideas unless it's a defense contract or something.

i have a bosch cordless driver

7.2v with a hex drive

runs up to 10 nm and has 10 torque settings and pretty consistent as i use the low settings for screwing into plastic panels and larger for other items

i dont know if they still are available as i have had this for about 3.5 years , used daily and charged weekly

small , lightweight , with plenty of grunt
