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 black inserts were

developed for the FA series machines. 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.

Quick change cutterheads on Rottler boring

machines can be easily changed. The quick-change

draw bar system pulls the cutterhead into the spindle

and firmly locks it into the internal taper for chatter

free cutting. Cutterheads are available to machine

from 1.5" (38mm) to 9.0" (230mm). Different design

cutterheads are available for production thru boring,

blind hole boring, and heavy duty large diameter

boring, sleeving and counterboring. Shown here

are typical cutterheads for small diameter cylinder

boring, production boring and heavy duty, large

diameter machining.

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. Standard with

Cutterhead assemblies.

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.

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. Optional for standard production

cutterhead and production stub cutterhead.

Square Insert Indexable Toolholders

Operation and programming of Rottler’s FA Boring Machines is

done with ergonomical keypads positioned on the front of the

machine. Rottler pioneered the development of this simple

method of operation and the display tells the operator exactly

where the spindle is positioned at all times. Programmed

information such as depth of cut, speed, feed is clearly displayed

so the operator knows the machine movements at all times.

Programs can be stored in the machines memory for future use.

FA models are programmable

for Automatic Cycles. Press

cycle start and "walk away",

the machines will center, bore

to the exact depth. When

boring for new sleeves, the

exact length of the sleeve can

be programmed eliminating the

need to cut down the sleeve

after installation saving time.

Optional blind hole software

pauses the machine after

centering to allow the cutting

tool to be installed in the cutterhead.

The electronic handwheel on the

FA machines has 2 modes of

operation. In coarse mode, each

"click" of the handwheel will move

the machine exactly .001" (.01mm)

and in fine mode, each click will

move the machine exactly .0001"

(.002mm).
