CORNER/HOLE
TEMPLATE
A template to rout
holes in various
diameters and
concave or
convex curves.
■ Made from 8mm clear PETG
plastic.
■ A template profi ler cutter can be
used to create holes of 25mm,
50mm, 75mm and 100mm in
diameter.
■ The template edge also includes
a concave and convex 50mm
and 100mm radius curves.
■ A variety of other size holes
and curves can be achieved by
using a different combination of
cutter and guide bush*
Size: 290 x 290 x 8mm
*A Unibase may be required for certain
makes and models of router.

REF. TEMP/COR/A
Isolate router from power supply before
making any adjustments.
The template can be used with both bearing
guided router cutter. Bearing guided will
allow the same size holes to be routed. By
using different diameters of guide bushes
and cutters, varying sizes of holes can be
routed. Always rout in a clockwise direction
taking shallow passes. Always clamp
template using two clamps, ensuring they will
not foul the router path.
EXACT SIZE HOLES
Exact size holes can be routed using shank
mounted bearing guided prole cutters.
Pre-drill a start hole before trimming/proling.
Ensure depth of cut is set so that the bearing
will contact the template edge.
OTHER SIZE HOLES AND CURVES
Other sizes can be
achieved by
changing cutter and
guide bush
diameters. When
using guide bushes
there is a gap
(offset) between the
cutter and the guide
bush diameter to
allow clearance.
This offset should be
a minimum of 3.5mm between the cutter
diameter and guide bush diameter. Add 7mm
to the cutter diameter to give the minimum
guide bush that can be used.

FORMULAE FOR OTHER SIZE HOLES
Hole diameter required equals cutter
diameter plus template hole diameter minus
guide bush diameter.
E.G. FOR A 30MM HOLE DIAMETER
Option 1 - Use a 50mm template hole with
40mm guide bush and 20mm diameter
cutter.
Option 2 - Use a 50mm template hole with
