RCBS Carbide Replacement Cutter for Trim Pro 3-way Cutter - Manual (Page 2)

Pilot (F) and bottom out case mouth on the cutting flutes of the
Carbide Cutter Head (J).
5. Lower the Outside Deburring Cutter (C) until it just makes
contact with the case, by rotating Thumb Screw (B) clockwise,
and tighten the Outside Deburring Cutter Setscrew (D) to secure
Cutter in place. NOTE: the Outside Deburring Cutter (C), should
just make contact with the case. Do not drive cutter into the
case as this can cause damage to the cutter. Remember when
you deburr a case all you want to do is remove any burrs from
the case mouth. Final adjustments will be discussed later.
6. Ensure Cutter Orientation is similar to that in Figure 1.

ADJUSTMENTS
Once assembly has been completed some adjustments will be
required for the Chamfering Pilot and Outside Deburring Cutters.
1. Adjust the case trimmer for proper trim length. (Refer to your
case trimmer instructions). Trim case.
2. Remove case from case trimmer and check overall case
length, amount of chamfer on the inside of the case mouth and
the amount of deburr on the outside of the case mouth.
3. To adjust the inside case mouth chamfer, remove the cutter
from the trimmer, loosen the 8-32 x 1/8 Setscrew (G) while
holding pressure on the end of the Chamfering Pilot (F) with your
finger and adjust the 6-32 x 3/8 Setscrew (H), at the rear of the
cutter, clockwise to increase the amount of chamfer and counter
clockwise to decrease chamfer. NOTE: A 1/8th of a turn on the
adjustment screw will change the chamfer depth by .004". Once
set, retighten the 8-32 x 1/8 Setscrew (G).
4. To adjust amount of outside case mouth chamfer, the cutter
can remain on the trimmer, loosen the Outside Deburring Cutter
Setscrew (D) and rotate the Thumb Screw (B) clockwise to
increase amount of chamfer and counter clockwise to reduce
amount of deburr. NOTE: An 1/8th of a turn on the Thumbscrew
will change the deburr depth by .002". Once cutter is set,
retighten the Outside Deburring Cutter Setscrew (D).
5. Repeat steps 3 and 4 until you are satisfied with the amount of
inside case mouth chamfer and outside case mouth deburr.
6. Ensuring the cutter orientation is the same as what is shown
in figure 1, will reduce the amount of brass chips that can build
up around the Outside Deburring Cutter and the Chamfering
Pilot Cutter.
7. If the 3 Way Cutter binds on the case or does not chamfer
correctly, condition A may exist, as shown in Figure 2. Loosen
the 8-32 x 1/8 Setscrew (I) and position the Carbide Cutter Head
(J) so the leading edge of the Cutter Head is lined up just past
the tip of the Outside Deburring Cutter (C), as shown in condition
B, and retighten the 8-32 x 1/8 Setscrew (I).

cases begin to vary or the cutter stops trimming and deburring,
remove the cutter assembly from the cutter shaft and clean the
cutter by removing any brass shavings that may have built up on
the cutter.
