I wouldn't count on those setting to give you an accurate torque reading, the torgue setting are so that you don't counter sink screws to far or strip the heaes. Obviously the setting go from zero to fully closed. the increments usually go by units of 10 ft lbs, but are not all that accurate.

My Dewalt cordless drill, model DC970, is fully charged and turns. However, when I try to turn a screw, the drill does not move. What should I do?


There is a collar that controls the torque of the driver just behind the chuck. Rotate it until the drill icon lines up for full power.

Don't know how to use a Dewalt cordless clutch driver/drill to tighten a nut to 40-50 ft-lb


Hi katie. To "torque" a nut, you need a torque wrench. Most auto parts stores will have one that you can borrow. J.

Works but when a load is put to it the chuck just stops,motor in still running, is the the clutch or the trans


Could be the clutch but before replacing try this first. Make sure the gear/switch selector is fully engaged, try shifting a couple times. Try rotating the clutch collar to increase the torque demand on it and if both these don't work you will probably need to see about replacing it. Let me know if you need more assistance.

How do you loosen the chuck so that a different bit can be installed


If you lower the torque setting, you can just hold the chuck with one hand and pull the trigger (put it in reverse), then change the bit and reverse your order of operations.
once complete, increase the torque setting to where it was.

Amount of torque per setting in dewalt dc925 xrp


The torque settings are not tightly controlled so they are not all that repeatable from drill to drill. They also vary somewhat with the speed of the drill and the condition of the battery. And they aren't linear (a setting of 10 is not twice the 5 setting) Simplest thing to do for a rough idea is to use your hand to hold the chuck still to feel how much torque you have at each setting. (start low and grip it tight!) If you want a specific torque setting, say 10 ft-lbs, then put a stout screw in a scrap of wood, hang a 10 lb weight on it 12 inches from the screw and adjust until it just starts to slip.

Is anyone there? need Dewalt help


Here is DeWalt's marketing thing on the subject.

http://www.dewalt.com/us/cordless/powerrating/

Unit Watts out (UWO) is their rating for the (presumably sustainable)maximum power output at the chuck of the drill. You can read about it..their explanation is basically technically correct.

Yes, max torque is related. The maximum power in a permanent magnet DCmotor system occurs at half the maximum speed when the system is loadedwith half the maximum torque.

1hp = 746 watts, DeWalt's DC900 36V drill is claimed to be 750 watts,close enough so let's call it 1 HP ok? Their max RPM is 400. So 200 RPMis the half-way point.

1HP = 200RPM*Tmax(in-lbs)/(24*5252)

Tmax = approx 630 in-lbs

The equation I used is known equation for relating power (HP) to RPMand torque (in ft-lbs..I added in the factor of 1/12 to account for thein-lbs to ft-lbs conversion).

By the way DeWalt make some bold claims about other manufacterers' drills.

For example they claim the 18V Lok Tor by Milwaukee puts out 390 UWOcompared to their DC988 model listed as 420 UWO. Yet I have readinformation from Milwaukee's own independent tests that claim the LokTor drills faster 2 9/16" self-feeds AND more self-feeds per batterythan that very DeWalt model.

This was posted on Milwaukee's Tool Talk forum (when it existed). Ibelieve the Milwaukee official said that DeWalt averaged 7.2 secondsper hole while the Milwaukee averaged 6.4 seconds per hole. I make beoff slightly but I do remember it was around a 1 second difference.Plus the Milwaukee apparently drilled 28 holes per batt where dewaltwas 25.
