REVERSIBLE STILE AND RAIL SETS
The stile and rail assembly allows the stile and rail parts of a
door frame to be easily machined with the same router bit by
reversing the components. The stile and rail bit comes complete with a ball bearing guide and shim set. This reversible
stile and rail set has been designed to produce raised panel
cabinet door frames using 3⁄4" material. It cuts a 1⁄4" x 3⁄8 "
tongue and groove in the stile and rail.
It is advisable to first use the reversible stile and rail bit on test material to familiarize
yourself with its use. When cutting rail stock to length, it is not necessary to add extra
length to compensate for the rail tenons. The metal shim set included with your bit is used
to adjust the tightness of the joint if necessary. For safety and best results, we recommend the use of a table mounted router with adjustable fence(s) and miter gauge.
Step 1: Cutting Rail Ends
Assemble the router bit assembly as shown in Figure A. Make sure the fully exposed carbide appears on the left of the bit
as shown below. Failure to do so will effect performance and ⁄ or can result in serious injury. Do not use shims at this time.
When cutting rail ends, use a miter gauge or jig.
Note: The workpiece must always be fed against the cutter rotation and the full depth of profile should be made in one pass
to ensure a precise cut. Before turning the router on, set the rail on the table finished face up. Slide the miter gauge up to in
and move both up to the router bit. Slide the lumber along the miter gauge face until it contacts the bearing. Pull miter gauge
and stock back from the router bit before starting router. We recommend using a back-up piece of wood against the rail to
prevent end grain tear-out. Rotate the board end for end, maintaining the face-up position and cut the other end. A clamping device may be necessary to keep the workpiece secured against the miter gauge.

•Failure to follow theSE guidelines will result in serious personal injury.
•ALWAYS WEAR ANSI
APPROVED EYE AND EAR
PROTECTION WHEN USING
THIS BIT.
•The use of a router table is
strongly recommended.
•Never feed lumber with the
rotation of the bit.
•Follow the safety guidelines
set forth by the manufacturer
of the router and router table.
•Always make sure the router
bit components are tight, the
bit is secured in the router,
AND the wood is free of
defects or nails.
These router bits have sharp
edges. Use care while removing the waxy protective coating. Never turn on the router
with the protective coating
still on the bit.

Step 2: Cutting Stile and Rail Edges
To shape the stile and rail edges, disconnect the router from the power source and reposition the cutters and bearing as
shown in Figure B. Do not use shims at this time. To remove the nut on the end of the bit, leave the bit chucked in the
router’s collet and use the spindle lock on the router or the wrench for the collet to stay the spindle. Line up the router table
fence(s) with the guide bearing on the router bit. Check it with good quality straight edge.
Figure B.
OTHER CONSIDERATIONS
If this is your first time performing panel door construction, start simple by making a square door. Doors having more intricate designs such as arched, tombstone or curved panels should only be done when you are confident of your ability . If
your project requires curved pieces then freehand shaping will be necessary. Remove the fence(s) and always incorporate
the use of a starting pin or block to support
the workpiece as it is initially fed into the cutter. Always use some type of jig or hold-down
device to make the operation safer and to
avoid having your hand in close proximity to
the spinning cutter.
We stress the importance of working with
good quality material and insuring that all
pieces are machined the same and that all
ends and edges are cut square. Follow all
recommended safety procedures and always
test your setup using sample pieces.

panel door components. For router bits to

BEARING
WITH FENCE
Re-check the height and position of the cutters before making the edge profile cut to ensure that the face of both pieces
being joined will align properly.
The position of the profile on the workpiece and variance in material thickness will also affect alignment. It is therefore very
important that the test material is milled to the same thickness as your finished pieces to make an accurate setup.
ADJUSTMENTS
Join the two pieces together and judge the quality of the joint. If the tongue fits too loosely, go back to Step 1 and place a
metal shim between the guide bearing and the 1⁄4" straight cutter and re-test. Repeat this process until desired fit is achieved.
If the two pieces are not flush, re-check height adjustment. See Figure C.
