Kennametal S16-NEXR05 Indexable Grooving Boring Bar

Kennametal S16-NEXR05 Indexable Grooving Boring Bar — 2" OAL — is a tool designed for internal grooving within bored holes. As an indexable bar, it uses replaceable inserts to supply the cutting edge, enabling multiple edges per insert and reducing the need for complete bar replacement. The S16-NEXR05 designation places this item within Kennametal’s lineup of indexable grooving boring bars, reflecting a standard interface used by the manufacturer. In metalworking applications, it is employed to form grooves along the interior surface of a bore, providing a controlled, internally routed cut during grooving operations. The 2" overall length indicates a short-reach form factor suitable for compact setups where tooling envelopes are constrained. This combination of an indexable edge system and a dedicated grooving bar from Kennametal supports efficient, repeatable internal grooves on bored parts, making it a practical choice when a dedicated grooving solution is required.
