There is three different style insert blanks.

A - Style Blank insert,

RCA

is a small insert for all standard applications.

B - Style Blank insert,

RCB

in design for long profiles like High Performances profiles with multi angles o

Radius or other special applications
C - Style Blank insert,

RCC

is a much thicker insert for Heavy Duty tooling and can be use for hard seat

materials (will work only on the Large Inserts holders series 3000 style insert holders, for the 20.00mm
tooling)
Special Order - Special Profile Carbide Cutter Bits are generally considered to be "Customer Proprietary".
These are uniquely numbered, exclusively for the ordering customer; prices will vary depending on
quantities and additional charge for initial run.

RT312 Insert, triangular positive rake, 3/8 1/32" (.787mm) radius, for the TH3000 series insert holder and
RT212 Insert, triangular positive rake, 1/4" (6.35mm) 1/32 “ radius for the TH2000 series, for hard seat
materials applications (Counterboring and straight angles only )

Carbide Pilots

See Carbide Pilot catalog for a complete list of Pilots available.

Rottler Solid Fixed Carbide Pilots

are manufactured from fine grain sintered tungsten carbide

and are ground to a very high degree of accuracy, straightness and surface finish - designed for a life
time of precision machining!

The part number of the pilot represents the actual diameter in metric of the straight/parallel part of the
pilot where the pilot fits into the valve guide.

For example:

FCP0700

means that the diameter of the part of the pilot that goes into the valve guide is

7.00mm

(0.2756”)

FCP1270

means that the diameter of the part of the pilot that goes into the valve guide is

12.70mm

(0.5000”)

Pilots are available in increments of .01mm (0.0004”). Normally, a small amount of clearance approx
.01mm (0.0004”) is required between the pilot and the valve guide.

Most new valve guides are manufactured to a

nominal size

and the valve stem diameters are

manufactured to be smaller than the nominal size to allow clearance for heat expansion of the valve stem
when the engine is operating. For example: a 7mm valve guide has an internal diameter of exactly
7.00mm (.2756”) The valve stem diameter of the intake valve is 6.98mm (.2748”) and the exhaust is
6.96mm (.2740”). In order for the pilot to fit most all valve guides, the first choice could be FCP0699 to
give .01mm (0.0004”) clearance. If the valve guide is used and has some wear, then the second choice of
pilot could be FCP0700(0.2756”).

Rottler makes 3 sizes of shanks of pilots:
6.00mm (0.2362”) for small valves guides 6mm (0.236”) and below. The part number for these pilots is
FCPM.
0.375” (9.52mm) for common size valve guides, 6-14mm (.236-.625”). The part number for these pilots is
FCP.
20mm (0.7874mm) for large valve guides for SG80A machine. These pilots are made to order
specifications.
