Do you mean the jaws of your keyless chuck slip or the torque setting of
your clutch slips?
Many clutches can be set up for increased torque & some can't, older
Makita's for instance can have one or two torque washers added to beef up
the clutch, some makes if you remove the chuck & open the clamshell can have
the torque increased by turning the change ring back a notch or two, some
have a threaded inner clutch cam that can be rotated forward so that when
you replace the change ring in the correct position the torque is increased
considerably. DeWalt have used a few different style clutches, not normally
prone to slipping unless the clutch housing assembly has cracked.
Sometime if the hi/lo shifter does not fully engage the orbital gears the
clutch will appear to slip when actually it is the gears slipping out, this
may be due to dirt, lack of lubrication, worn gears or bent or worn shifter
If it is the chucks jaws that slip, replace the chuck with a better quality
one...there are some excellent heavier duty keyless chucks available these
days, some with a very effective lock once tightened.
I brought this up a couple of months ago and I seemed the only one with this
slipping problem . I would like to replace my keyless chucks with keyed ones
I dont know I folks know this but keyed chucks can be tightened he same way
keyless ones are . I have been tightening chucks that way for 50 years only
using a chuck key when doing heavy drilling operations.....mjh
Good point, Mike. So have I.
To the OP...
Clean up the inside real good every now and then. I use alcohol to
get all the grime off...then hit it with a medium-tooth file to rough
it up a bit. I seem to get about 3 months or so out of 'em this
way...then need to clean again.
And the same should be done to the bits, too.
But that doesn't solve the problem entirely. You just can't get the
same torque by hand that you can with a tool.
Have a nice week...
Follow Joan Rivers' example --- get pre-embalmed!
My experience is just as yours.
I can recall many years ago, when Keyless chucks were rare and
expensive, using them on milling machines.
They worked just fine, and the demands were much more arduous on a
My conclusion, keyless chucks on lo-cost price competitive tools are
just c**p, and should be replaced with a keyed type.
