I have a DC925 drill that is starting to just make a whirring sound istead of turning when I try to bore holes in wood. Is this a clutch going bad or something?

You will find them in the transmission, remove the metal cover and they will be located just under it - sounds like it is either the gear posts or the clutch cams on the nose side of the transmission DeWALT DC925 Type 1 Hammer Drill Parts
Soap might work. Some use candle wax, bees wax, WD 40. I've prayed silicone on the drill bit. Using moderate pressure and low speed definitely helps, and it is essential to clear out the hole of chips frequently. So drilling in increments works. You drill a little, lift the bit up out of the hole to clear the chips. Also the type of bit used is a factor in drilling efficiency: wood boring bits are a good choice. Forstner bits are excellent, and spade bits are just OK. Hope this helps....
Try turning the ring to 2 or 3 and run the drill holding the chuck so the clutch slips then try turning it to drill setting. Also try to do it in different speed settings. If not it sounds like a fault in the gear module. It might just be a metal clip just under the clip in side. Undo the 4 screws holding the gearbox onto the housing and carefully remove it, you might see the fault or loads of dirt that needs cleaning. Go to http://www.2helpu.com/world/map.aspx for a drawing.
hi
like most clutches on hummer unit after the assembly has been done you will a way to tighten the spring clutch look for adjustment to make the spring looser and tighten
They refer to the relative tightness of the adjustable built in clutch. The lower the number, the less torque is applied before the clutch starts to slip. At the drill image on the ring, there is no slippage.
Why would you want such a thing??? Well because you don't want to strip a screw yo are installing or possibly break it. Whether you are putting small screws into soft wood or you are installing "TapCons" in concrete, this is a very good feature to have on your DeWalt or other fine battery powered device.

They all do that a bit. The sparks when starting up and stopping are normal. If it has been used alot brushes may be a good idea but before they need to be changed it will spark quite a bit.
It will not hurt to inspect the amount of brush material remaining.
Sounds like your starter solenoid is not engaging. Try tapping it with a dead blow hammer or a hammer and block of wood (gently! Not to hard!) If it bumps over that is your problem. Also check all connections to solenoid and starter.
The whirring noise you are hearing is your starter motor but your bendix gear is not engaging.
try shifting the high/low switch to make sure fully engaged. Also make sure that all the other positions are correct and if so then you have a clutch problem. For a breakdown you can go to Dewaltservicenet.com and get a parts breakdown and list for this tool. Good luck and if I have answered your question would you please rate this response accordingly.
