Introduction
The T30027 Pocket Hole Guide is a jig for creating
quick, incredibly strong joints. It can be attached
to a workpiece or mounted to a bench. Including
everything needed to get started, this jig creates
post and rail, curve, edge-to-edge, mitered frame
corner, square corner, and T joints. The T30027
comes fully assembled.

Mounting
The most common way to mount the jig is securing it to a bench. It can also be clamped directly
to the workpiece. The built-in clamp allows for
hands-free drilling during either procedure.
Operating Adjustments
The rubber foot on the clamp has a threaded shaft
and jam nut that can be used to adjust clamping
force against the workpiece (see Figure 6).
To mount guide to bench:
1. Secure jig to bench using (3) wood screws
(not included).
For additional workpiece support, attach

scrap boards 7⁄16" thick flush with sides of jig
bed, as shown in Figure 4.

To move clamping mechanism:
1. Remove (4) button head cap screws that
secure clamp mechanism to jig bed (see
Figure 7).
2. Align clamp mechanism with threaded holes
in jig bed (see Figure 7).

Drill Bit Depth
When attached to the step drill bit, the stop collar is used to control pocket depth. This also
determines the length of screw that will join the
workpieces together.
4. Loosen set screw just enough to set step drill
bit tip 1⁄8" from jig bed, as shown in Figure 11.
To adjust stop collar:
1. Remove workpiece from jig, and ensure stop
collar set screw is flush with inside of stop collar using 2.5mm hex wrench (see Figure 8).

the collar up or down the step drill bit will
allow for deeper or shallower pockets and
determine fastener length.

wear safety glasses when
using this tool.

Preparing Drill Bit Bushings
Before using the jig on a workpiece, create multiple pocket holes on a scrap board. This sets the
bushings flush with the columns and smooths
uneven surfaces between the stop collar and
drill bit bushings. This results in a consistent and
accurate drilling depth for this jig (see Figure 12).

Adjusting Pocket Hole Spacing
The Pocket Hole Guide can provide approximately 1
centers while clamped in a single position.
To adjust spacing:
1. With 4mm hex wrench, loosen button head
1
⁄8" to 3" of spacing between pocket hole
cap screw beneath scale until columns slide
freely on column pin (see Figure 13).
