REAMERS

Setting Methods

There are two optional setting methods - comparison
micrometer and setting device.
Comparison micrometer with dial gauge, although
a low cost solution and readily available for small
workshops, is prone to damaging the cutting
edge and therefore not recommended.

Using a Comparison Micrometer
Set the micrometer to the correct diameter using the
precision blocks.
Adjust the frontal diameter and back taper by turning the
adjustment screw clockwise.
The frontal diameter should be larger than the rear
diameter by approximately 0.015 mm.(0.6 µin)
Using a Setting Device
ISCAR’s mechanical setting device enables
easy, quick and accurate adjustment.
Due to its modular construction, it can
be used for standard, special and more
complicated reamer adjustments.
Setting Device
Located Between Centers
• Shorter setting time
• Modular system
• Higher accuracy
• No risk of damaging the cutting edge
