Rottler offers several different styles of indexable

coated carbide inserts. The square inserts are used

for standard oversize boring applications. The gold,

square insert, R4, can be used from 400 to 650

RPM’s. The new high performance R2 insert, with its

purple color, was developed to be used with the F3/F5

series boring bar. It is capable of standard to heavy

cuts up to 1200 RPM’s. Triangular inserts work well

where cutting a bore to a square shoulder is needed,

such as sleeves or counterbores. The black coating

provides a tough finish capable of heavy sleeve cuts

at high RPM’s. The gold coated inserts provide a

sharper edge, and better finish on the cutting surface.

Ideal for counter bores or finish cuts. Both styles of

triangular inserts are available with 1/64” (0.4 mm) or

1/32” (0.8 mm) radius cutting tips.

This heavy-duty machine was designed for standard

and large capacity machine work. The spindle diameter

has been increased to 3.25" (82.5mm) for extra heavy

duty machining up to 9" (230mm) bore size. Large

sleeve cuts can be taken at high spindle RPMs, and

in many blocks, one pass sleeve cuts are possible to

increase productivity. Programmable counterboring

operations with the A model eliminate guesswork and

provides added timesaving. The massive one piece

meehanite, stress relieved, precision machined base

casting allows the fixturing of large diesel blocks such

as Cummins 855, Detroit 12V71, Mercedes 444V12

and odd jobs such as gear cases and connecting rods.

The F8 machines can also handle small jobs down to

1.5" (38mm) bore diameter with optional cutterheads.

These toolholders are used for general boring to heavy stock

removal. Square inserts have 8 different cutting edges,

making them very economical. Can be used with either

Rottler R4 or the new R2 insert for high performance cutting

up to 1200 RPM. Available for standard production

cutterhead and production stub cutterhead.

Square Insert Indexable Toolholders

The ‘Positive Rake’ of these tools reduces cutting pressure,

allowing you to take a larger cut. Triangular toolholders

are used for sleeve cutting or counterbores. Different insert

styles are available for your application.

Triangular Insert Indexable Toolholders

These tools were designed for V-Block applications where

main bearing interference at the bottom of the bore is a

problem. They provide an additional .25” of cutting depth

compared to standard tool holders. Available currently

from 3.48 - 4.32” Dia.

Coated Carbide Inserts

Rottler Manufacturing offers a wide variety of brazed carbide

tool bits to handle applications such as facing and

counterboring, offset tools for blind hole and tight clearance

situations, special grooving tools, etc.

Special Tool Bits

Tooling

Flexibility

The F Series machines have variable feed rates that

allow you to maximize the performance of the machine.

Increase spindle feed rates for simple oversize bores.

Decrease feed rates for sleeve cuts or counter bores.

The F8 machines can bore from 1.5” (38mm) to 9”

(230mm) in diameter, with optional cutterheads. The

F7 machines can bore from 1.5” (38mm) to 5” (127mm).

Special carbide tools are available for counterboring,

chamfer cutting, offset boring, and O-ringing.

Automation

The A models have

programmable boring cycles

and automatic centering cycles.

Both models will store up to 100

different boring programs.

Each program stores boring

depth, spindle speeds, and feed

rate. Automated cycles reduce

costly errors while freeing

operators to perform other

tasks. The F8X can bore a

complete block blank

unattended.

Reliability

The F Series machines use a

high-speed, cogged belt drive

system. This, and the use of

two independent motors to run

the spindle speed and feed,

entirely eliminates the gear box.

With fewer moving parts, and

a superior design, the F Series

becomes a much more reliable

boring bar than other designs

of equipment

Cost Savings

The high speed Rottler F

Series machine can bore

a block in half the time

that other models

of boring

machines

require. New

insert technology is

producing long lasting,

inexpensive inserts which

are capable of

handling these

high speeds and

feed rates, with

the same cost per

insert as previous

styles. Inserts do not

require sharpening and the

low cost of these tools makes

them the ultimate choice for

boring cylinders.
