When setting the torque how do you know what setting to what size screw or what is the general rule of thumb about using the power tools small screw what torque? long 15 inch screw what torque etc. I can never get it right
Hi, they usually list the torque to screw size ratio in the instruaction manual. If you cant locate yours many companies list their instruction manuals pn the web on their home page, or you can sneek a peak at a hard ware store on a similar drill.
The usually rule for small screws is torque 1-4 on small screws.
Otherwise practice makes perfect & different types of timber will affect when the torque kicks in.
I still believe that an impact driver is better than a drill with screws as it impacts the screw in & this gives you better control. It will actually slow the screw down & you can recess it just perfectly. The drawback is that it can snap small screws when driving into soft timber. (but you can always predrill)

The greatest one that fit most chucks are 13mm but remember to remove the torxscrew (in clockwise direction) inside the chuck first and if you use a new chuck beware of to use some loctite on the screw.
The long side in a vice the short in the chuck and turn the left anticlockwise direction the L direction and pull short but fast the trigger and move the drill in the same direction turning the drill has priority to make doing this in a very short time. to not overcharge you tool.
Battery powered drills generally are much weaker thah house current drills. With that in mind, realize that they aredrills and not intended to be power screwdrivers! The less the supply voltage, the less the torque (turning power). They are suppurb at doing small jobs where torque is not an issue, like using drill bits through wood, etc!
Your drill will drill a hole at any speed, the drill bit needs to be sharp to drill the mateirial.The type of wall material is important.Drywall is soft but a masonry bit should be used.A masonry bit has a flat bar accross the point and slower speeds are best.Wood walls / studs you need wood bits that are sharper and medium to high speeds are used.Concrete or Block walls again require Masonry bits.If very hard concrete as in foundation walls or filled block the use of a Hammer drill will work much faster.Good Luck
Open the chuck wide open. In the center is a retaining screw, they usually have left hand threads. Remove the screw. Take an allen wrench 1/4" to 3/8" in size and fasten the short side tightly in the chuck. The chucks are usually right hand thread, so take a small hammer and strike the allen wrench to turn the chuck to the left to loosen it.
Once you have the chuck off, verify the thread size of the drill motor shaft, then go to McMaster-Carr and choose the one you need.
The torque settings on a drill will stop the drill from driving the screw ( or what ever you are tightening ) when it reaches a specific "tightness" . For example; the setting "1" will only tighten a screw a very little bit, while " 14 " will tightten the heck out of it.
Note: once the screw has reached it's specific torque ( or tightness ) the drill motor will continue to turn but it will disengage the driver, making a kind of grinding sound,it's perfectly normal so don't be alarmed.
Sorry, there are no rules as to what to set torque to for your job. There are too many variables like thickenss of the wood or drywall or the hardness of the material you're driving into and whether you want the screw to stop above, at or below the surface. The best thing to do is set it low and raise the torque untill it stops when you want it to. Keep in mind if you hit something like a knot it will stop the screw earlier and if you go through a softer spot in the wood it will drive in deeper.
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.
you are half right. The screw that you see is a chuck retaining screw (LH thread) to keep the chuck from loosening up when in reverse. What you need to do is if you have one remove it first and then find a bent handle allen wrench about the size of the chuck capacity, lock the shorter end in the jaws and then position the wrench at about a 30 deg angle and put the chuck on a block of wood or bench and take a hammer and hit it counter clockwise. If you have a wrench small enough to lock onto the spindle use it and brace it on the bench. If this tool has a high and low setting use the low and if clutch equipped the drill only.
