I just received this 21V 350 in-lb impact drill https://www.amazon.com/gp/product/B088JYH44C/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
The 350 in-lb torque rating seemed kinda decent so honestly I expected better results than I am getting. I am wondering is it
- "user error" (my first impact drill here)
- expected limitations of this modest tool?
- different bit extender needed
The tests I did:
With a two inch thick oak board:
- drive a screw as deep as I can
- drill out a 3/8 inch hole with a spade bit
In both cases they just gave up at one inch depth. Bits would come loose and wobble, and no further progress could be made.
As far as tightening/locking the bit: I watched a few youtube's and they talked about higher end dewalt/milwaukee etc that have locking mechanisms. This tool does not have a similar mechanism. Even so the instructions mention
The bit is secure when the chuck makes a ratcheting sound and the sleeve can not be rotated any further".
I did not hear any ratcheting sound even though the fit is tight (before drilling).
Based on a comment I will make the implicit goals here explicit:
"What needs to be done (if possible at all) to achieve"
* two inches of screw fastening in oak
* two inches of 3/8 inch spade boring in oak
The answers may be some combination of:
- drilling type settings: classic vs impact vs hammer (latter not likely..)
- speed settings: 1 (low speed higher torque) 2 (high speed lower torque)
- ratcheting settings: 1 to 25
