Adjusting the Square Carbide Inserts
• The micrometer should be used.
• Set the Digital micrometer (BM) according to
the valve seat insert diameter and the required
interference.
• Slide the tool holder without the pilot on the
micrometer.
• With the setting screw, adjust the square tip holder offset.
IMPORTANT:
When 90 degreed bits (RCA512) or the Triangle bits are fitted, check that their reference
faces are perfectly clean.
The accuracy of the seat angles depends on this:
• While rotating the assembly tool holder/carbide tip holder, the carbide bit’s cutting edge should just
touch the micrometer spindle.
• Once in contact with the micrometer spindle, the carbide tip should not be moved at all. If this is not
observed, the cutting edge may be damaged and the resulting surface quality, when machining, will
be deteriorated.
