Iscar 5506627 XCMT08MF IC908 Indexable Drill Insert

Product Description

The ISCAR 5506627 is a solid carbide indexable drill insert carrying the XCMT08MF geometry and IC908 manufacturer grade. It is designed for use in indexable insert drills as the cutting element that engages the workpiece during drilling operations. The IC908 grade features a PVD coating process, delivering wear resistance and edge retention across a broad range of workpiece materials. The insert has an inscribed circle of 0.3323 inches, a thickness of 0.1252 inches, and an included angle of 83.5 degrees. The MF chipbreaker geometry promotes efficient chip formation and evacuation in demanding drilling cycles. Installation and replacement are performed by licensed machinists or CNC tooling technicians.

This insert is intended for use in ISCAR DRDRILLS series indexable drill bodies. Its universal primary workpiece material designation covers ISO material groups H, K, M, P, and S, making it applicable to a wide range of metals including steels, stainless steels, cast irons, non-ferrous alloys, and high-temperature alloys. Typical applications include through-hole and blind-hole drilling on CNC machining centers and lathes in both production and job-shop environments. The insert size code is 08, corresponding to insert size 080304.

Key Features

• IC908 PVD-coated solid carbide grade for extended tool life across universal workpiece materials
• XCMT insert style with MF chipbreaker for controlled chip formation during drilling
• 83.5-degree included angle geometry suited to standard drilling applications
• 0.3323-inch inscribed circle and 0.1252-inch thickness to ISO 13399 insert size 080304
• 0.40 mm corner radius balances edge strength and surface finish
• Relief angle of 7 degrees provides clearance to reduce flank wear

Compatibility

Designed for use in ISCAR DRDRILLS series indexable drill bodies accepting XCMT style inserts with insert size code 08. Material grade coverage includes C1, C2, C6, and C7 classifications. Verify drill body seat geometry and clamping torque specifications against the ISCAR DRDRILLS tooling catalog before installation.

Installation Notes

Insert replacement should be performed by qualified tooling technicians following the machine tool builder and tooling manufacturer guidelines. Power down and lock out the machine before accessing the drill body insert pocket. Use the correct Torx or hex key specified by the drill body manufacturer when seating and torquing the clamping screw — do not substitute tools or exceed the body manufacturer's specified clamping torque. Inspect the insert pocket seating surface for chips or debris before installing a new insert.
