Concealed Fastener (KEIL Anchor): Field Drilling Instructions
Installers for projects with concealed anchors should be prepared to drill panels in the field. The KEIL Portable
Drilling Machine is REQUIRED for drilling concealed anchor attachment holes. Drilling machines can be purchased
or rented through TAKTL. Please contact your TAKTL Project Manager for more information and review the
following instructions thoroughly before operating the machine.
REQUIRED TOOLS AND EQUIPMENT
KEIL Portable Drilling Machine
Tri Flow Lubricating Oil
Lithium Grease
Clean Drilling Surface Waist-high Tables
Air Compressor + Hose with 1/4 in. Coupler
Water source + standard garden hose
Electrical source and small extension cord with circuit breaker provided
with drilling machine
Depth Gauge and shim for measuring hole dimensions
Safety glasses
Waterproof apron, boots, and gloves
SAFETY + WORK GEAR
Wear gloves as well as eye and respiratory protection when cutting TAKTL
panels. Safety Data Sheets for TAKTL panels are available on request.
ENVIRONMENT
Please adhere to all local, state, and federal regulations per taining to
the treatment and discharge of wastewater generated as a result of
cutting and drilling TAKTL material. TAKTL is a non-hazardous material for the purpose of wastewater classification. Requirements for
treatment of wastewater will be specific to project, site location, and
cutting/drilling conditions.
REQUIRED DRILL CONNECTIONS
Air The KEIL Portable Drilling Machine utilizes a
vacuum seal to maintain stability while drilling. In order
for the vacuum seal to function, an air compressor hose
with a 1/4in coupler is required.
Water The KEIL Portable Drilling Machine incorporates
a water cooling system to prevent overheating and to
facilitate the cleaning of slurry from holes as they are
being drilled. A standard garden hose will fit the water
supply line on the drill. Water can be turned on at the
source and will only flow through the machine when the
drill trigger is depressed. Water will spray out of the
center of the drill bit while the machine is running. The
water flow will shut off once the drill trigger is released.
NOTE: If water does not flow from the drill bit when the
trigger is depressed, please follow the steps outlined in
the section 6 of this document.
Electricity Each KEIL Portable Drilling Machine is
supplied with a small extension cord, equipped with a
built-in circuit breaker. The machine must be plugged into
this cord, then plugged into the power source to operate.
Check the reset button on the circuit breaker before use.

IMPORTANT
Before Drilling
01 Securing the Panel
Lay the panel face down on the
clean foam sheeting provided in the
shipping crate. Prep a clean secondary
table for washing and drying panels
after drilling. Set up staging rack for
completed panels. (FIG. A)
02 Preparing the Drill
Lubricate the slide rails with Tri
Flow lubricating oil and drill bit
attachment areas with litihium
grease as shown. Parts should be
lubricated every two hours when
using the drilling machine and at
the start of each work day. (FIG. B)
Wet drilling is required to reduce heat build up, sustain drill bit
life, and produce clean holes with the least amount of chatter.
Remember to maintain all TAKTL handling instructions while
staging, moving, thoroughly drying, and storing panels.

03 Calibration
To set the desired hole depth, locate
the depth adjustment bolt. (FIG. C)

04 Adjusting the Depth
Turn on the valve to actuate the
vacuum seal. Depress the front lever
until the drill bit touches the surface
of the material to be drilled. While
the bit is touching the material,
place the depth gauge next to the
adjustment bolt and turn the stop
washer until the bottom lines up with
the flange of the depth gauge (FIG. D).
05 Confirming the Depth
When satisfied with the adjustment,
tighten down the lock nut to secure
in place. Drill several practice
holes on a scrap piece of material
to tune the machine and make any
adjustments by quarter turns to
the stop washer. Turning the stop
washer clockwise will drill a more
shallow hole, counter-clockwise will
drill a deeper hole (FIG. E).
D
E
06 Preparing to Drill
Locate the hole markings or mark
the panel back with an X at the exact
hole location. Place the machine
over the X marking the hole location,
depress the lever until the drill bit
touches the surface of the panel.
Adjust until the bit is centered over
the X marking as shown (FIG. F).
07 Drilling the Undercut
Once the machine is in place, turn
the valve to actuate the vacuum seal.
Squeeze the trigger to start the drill.
With the trigger fully depressed,
press the black button on the side
of the machine to hold the trigger
in the ON position. Gently push the
lever down toward the panel surface
(FIG. G).

7.1 Drilling the Undercut
Drill small amounts of the material,
then slightly release the level to
allow the bit to retreat from the
panel so water can spray out any
slurry from the hole. Continue to
pump the lever until it bottoms out
(FIG. H).
7.2 Drilling the Undercut
While holding the front lever down
(FIG. G), depress the side toggle
lever (FIG. I) to kick the drill bit
for the undercut. Release the side
toggle lever before raising the bit
out of the panel with the front lever.

I
08 Using the Depth Gauge
After drilling each hole, review the
depth to ensure the anchor will
engage properly. Insert the end of
the depth gauge into the hole, then
depress the plunger as far as it will
go. Twisting in a clockwise motion
will help to seat the plunger. Don’t
be afraid to use some force (FIG. J).
09 Checking the Hole Depth
The amount of exposed shaft will
determine a passing or failing hole
as shown. If the plunger seats down
completely, remove the gauge and
place the U-shaped notch of the
shim under the flange (FIG. K).

9.1 Hole Fails
Depress the plunger again. If the
plunger seats fully with the shim in
place, the hole fails (FIG. L).
9.2 Hole Passes
If there is some of the shaft
exposed (1mm-2mm) with the shim
in place, the hole passes (FIG. M).

DAMAGE PREVENTION
Water Damage
• Keep panels uniformly wet during processing.
• Minimize the time panels are exposed to saw slurry water – do not
leave panels sitting in cut water for more time than is necessary.
• Thoroughly rinse panels after cutting, scrubbing with a plastic brush
if necessary to completely remove saw water residue.
• Dry panels with compressed air or an electric leaf blower after they
have been rinsed.
• Store cut panels in a vertical position with nothing touching the face
or back until they are completely dry.

Portable Drilling Machine User Guide: Maintenance
01 Clearing a Clog
Turn the machine on its side.
Press the trigger and insert a small
wire (such as a paperclip) into the
tip of the spinning drill bit (FIG. A).
WARNING: Water will spray from
the bit when the clog is cleared. If
the bit has been clogged for any
length of time, the initial burst of
water may be hot.
02 Removing Drill Bit O-Ring
Turn the machine on its side. Roll
the black O-ring (around the drill bit
shaft holding two set pins in place)
off of the shaft (FIG. B).
A
B
03 Removing the Pin Set
Gently remove the two set pins
from the shaft of the drill bit. These
will appear to be slot head screws,
but there are no threads and they
can be removed by hand (FIG. C).
WARNING: Do NOT operate the
machine without both set pins in
place and the black O-ring holding
them securely.
04 Removing Old Bit
Slide the bit out of the machine. If
the bit is stuck, gently push down
on the side toggle lever to loosen it.
When the drill bit is removed from
the mounting pin, make sure the
small gasket is still in place in the
tip. If it is not, it will also need to be
replaced (FIG. D).

05 Attaching New Bit
Place the new drill bit over the
mounting pin and align the set
pin holes with the recesses in the
mounting pin.
Insert the set pins into the shaft of
the drill bit, making sure they seat
firmly in place (FIG. E).
06 Re-attaching Black O-ring
Roll the black O-ring over the shaft
so that it seats into the notches on
the heads of the set pins (FIG. F).
E

07 Test
Turn the drill upright and gently
push the side toggle lever down. If
the toggle does not move, remove
the O-ring and set pins, turn the
drill bit 180 degrees and reinstall
the pins and O-ring. Over time, the
black gasket around the base of the
drill may begin to wear (FIG. G).
08 Removing Faulty Gasket
Pull the gasket out of the groove
around the base of the machine
and secure a new one into place. It
may have to be worked a bit to seat
completely into the groove (FIG. H).
