Changing Drill Bits
A DKDB drill bit drills 4000–5000 holes in Oak before re-sharpening.
This baseline was established using the factory settings for Feed Rate
Control described in this manual. Adjust your sharpening schedule
for your settings and the material being drilled.
WARNING:
!
Before changing the drill bit, disconnect the machine from the air
supply. Cycle the machine via the foot switch several times to remove air from the system.
(1) Remove the acrylic top plate.
(2) Loosen the collet with the provided wrenches.
(3) Slide the drill bit out of the collet and into the drill-guide
block until the end of the bit clears the collet. Slightly angle the
bit to avoid the collet and withdraw the bit from the drill-guide block.
(4) Insert a new or re-sharpened drill bit into the collet,
aligning the flats on the bit shank with the collet jaws.
(5) Tighten the collet.
(6) Re-set the counter to track drill-bit life and replace the top plate.

Drilling-Depth Stop
The drilling-depth stop controls drill-bit forward travel and the
drill-feed cylinder cycle. When the depth stop contacts the depth
control switch, the forward travel of the drill bit stops and reverses,
completing the drilling cycle.
WARNING:
!
Before adjusting the drilling-depth stop, disconnect the machine from the
air supply. Cycle the machine via the foot switch several times to remove air from the system.
(1) Loosen the wing nut.
(2) Push the drill-bit drive assembly forward to provide the
following clearances between the drill-bit pilot point and the fence:
½" [13mm] and ¾" [19mm] material:
1
⁄
8
" [3mm] clearance
1½" [38mm] material: 1" [25mm] clearance
Stock-Thickness Adjustment Fence Settings
The fence should be positioned so the pocket screw emerges
at the center of the material thickness. When adjusting the fence,
make sure it remains parallel to the front edge of the guide block.
(1) Loosen the four socket-head screws
located in the slot in the top of the fence.
(2) Align the face of the fence with the letter scales on the
edges of the base plate that correspond to the material thickness.
(3) Tighten the socket-head screws.
Setting A for ½" [13mm] material
Setting B for ¾" [19mm] material
Setting C for 1½" [38mm] material
(3) Adjust the depth-control adjuster until the head
fully depresses the plunger on the depth-control switch.
(4) Tighten the lock nut.
(5) Pull the drill-bit drive assembly back until it stops.

Sharpening a drill bit makes it shorter. When installing a
sharpened bit, readjust the drilling depth.
