Boring Internal Face Grooving Internal Face Recessing
HFIR/L-: MC Integral Boring bars
For shallow, internal face machining to max. 5 mm
depth of groove. One boring bar can be mounted
with inserts in 4-6 mm widths.
The initial major diameter groove is limited by
the insert’s geometry in each size.
After the initial groove, face recessing outward or toward
center is not limited by the insert’s geometry.
