Seco 00059714 SCGX09P1 T250D Indexable Drill Insert Carbide

Product Description

The SECO 00059714 is a solid carbide indexable drill insert designed for use in Perfomax series indexable drills. It carries the SCGX09P1 geometry with a T250D manufacturer grade and a TiAlN coating applied via PVD process. The insert features a square shape with a 90-degree included angle and a 7-degree relief angle. The inscribed circle measures 0.375 inches (9.53 mm), thickness is 0.156 inches, and the corner radius is 0.031 inches (0.80 mm). The micrograin carbide substrate and TiAlN PVD coating make this insert well suited for demanding drilling applications across a broad range of workpiece materials.

This insert is rated for universal primary workpiece material compatibility, covering material codes H, M, N, P, and S. That range includes hardened steels, stainless and high-alloy steels, non-ferrous materials, general steels, and superalloys. It is a standard insert for the Perfomax indexable drill platform and is installed by machinists and toolroom professionals in CNC turning, mill-turn, and machining center environments where repeatable hole quality and insert indexability are required.

Compatibility

Designed for use in the SECO Perfomax series indexable drill system. Insert size code 09, insert size designation 09T308. Verify seating and clamping fit against the specific Perfomax drill body before use.

Installation Notes

Indexable drill inserts should be installed by a qualified machinist following the drill body manufacturer's torque and seating specifications for the Perfomax platform. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the correct Torx or insert-locking key as specified by the tool body — do not substitute drivers. Inspect the insert pocket for chips or debris before seating a new insert to ensure full contact and accurate positioning.
