HFIR/L-: MC Integral Boring Bars Insert Initial Face Grooving Range
For shallow, internal face machining to max. .197” depth of groove.
One boring bar can be mounted with inserts of .157-.236” widths. The initial D
major diameter groove is limited by the insert geometry of each size.After initial
groove, face recessing outward or toward center is not limited by insert geometry. W Min. Max.
