View profile →An indexable insert gundrill cuts with a replaceable carbide insert instead of a brazed tip, so the tool is renewed at the machine by rotating or swapping the insert rather than by regrinding. It suits larger diameters and higher volumes.
PROTOOL's indexable gundrills cover 11.5 to 40 mm diameter with drilling lengths to 5,000 mm, up to about D×250 depth-to-diameter, holding IT7 tolerance.
Indexable insert gundrills reduce tool-change downtime on larger diameters where insert cost is a small share of total cost. On small bores, regrindable solid-carbide gundrills remain the standard.
