Ring Size Cutter
INSTRUCTIONS • USA/British Model #004-642 • Metric Model #004-643
READ FIRST
We know you are eager to use your new GRS Ring Size
Cutter. But, PLEASE familiarize yourself with proper
installation and operating procedures BEFORE you begin.
Improper installation and use could damage your new ring
cutter or cause personal injury! Thank you for buying a GRS
product.
INSTALLATION
The ring size cutter comes with its handle moved for
shipping. You must reposition the handle in order to use it.
First, remove the hex-head bolt and spacer located on the
cutter crank pin (FIG. 1). Slide the handle out and rotate the
cutter crank pin until you can replace the handle as shown
in FIG. 2. Replace the hex-head bolt with spacer into the
tapped hole in the handle and tighten.
Use the 4 metal screws provided to securely fasten the
ring size cutter to a workbench or table top. If these screws
are not compatible with your bench top, you must supply a
fastener with equal or greater strength. The shearing action
requires moderate force on the handle. The cutter must
be secured to safely absorb this force without pulling itself
loose from the workbench. Be certain that the ring cutter is
mounted properly to avoid possible injury.
Most users will want to mount the ring cutter near the front of
their bench. We suggest that you mount it back far enough
to allow for a “catch tray” under the cutter area to collect the
ring slugs. You might consider putting the front mounting
screws about 6" in from the edge of your bench. (FIG. 3)
CAUTIONS
Since this tool will cut metals, it will easily cut your finger or
most anything else you put under the cutters. You do NOT
need to have your fingers near the cutter when actually
making a cut. Once you are certain that the ring and cutter
are correctly positioned, remove your fingers and smoothly
pull the handle.
OPERATION
The ring size cutter is actually a special shearing tool. It
works by shearing a selected size of shank material from
the bottom of the ring. You control the amount of material
removed by selecting the corresponding cutter size. There
are seven cutter sizes that come with the USA / British
ring cutter: from 1/2" to 2", in 1/4" increments. These sizes
directly relate to ring sizes. Thus, if you want to reduce a
ring by 1 ring size, choose the size 1 cutter. It’s that simple.
For the metric version there are nine cutter sizes to choose
from. Once you have chosen the cutter size, you will then
need to correctly install the cutter for use. First lower the
handle to its full down position. Now, loosen the adjustment
knob (FIG. 4) by turning it counter-clockwise. Install your
selected cutter by placing its hole over the crank pin and
