Ingersoll Cutting Tools 5101214 Indexable Drill Insert SOMT08T306SK

Product Description

The INGERSOLL CUTTING TOOLS 5101214 is a carbide indexable drill insert in the SOMT series, designed for use in indexable drill bodies compatible with the QR drill style. This insert carries manufacturer grade IN6505 and features a multilayer MTCVD coating stack of TiCN, Al2O3, and TiN, optimizing it for cutting steel workpieces in moderate to high-demand drilling applications. The square SOMT profile provides a 90-degree included angle and positive rake geometry, supporting clean chip formation and reduced cutting forces. With four usable cutting edges and an inscribed circle of 0.311 inches, this insert delivers consistent performance across each index. Licensed machinists and toolroom technicians handling production drilling operations are the primary installers.

This insert is intended for steel cutting applications where controlled chip evacuation and coating durability matter most. The SK chipbreaker geometry suits general-purpose drilling into P-category workpiece materials, including carbon steels and alloy steels. It fits indexable drill bodies calling for an 08T3 insert size with the SOMT insert style and QR-compatible drill configuration. Typical applications include production machining centers, CNC turning centers with live tooling, and manual mill setups running indexable drills in metal fabrication or job-shop environments.

Key Features

• MTCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection in steel cutting
• Grade IN6505 carbide substrate optimized for P-category steel workpiece materials
• Square SOMT geometry with positive rake for reduced cutting forces and cleaner entry
• Four cutting edges per insert maximize utilization before replacement
• SK chipbreaker promotes controlled chip formation in through-hole and blind-hole drilling
• 0.024-inch corner radius balances edge strength with surface finish quality

Compatibility

Designed for use in QR-style indexable drill bodies accepting SOMT insert style in size code 08T306. Verify drill body manufacturer specifications for seating torque and pocket geometry before installation.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per facility LOTO procedures. Use the appropriate torx or hex key as specified by the drill body manufacturer to seat the insert securely without overtightening. Inspect the insert pocket for debris or damage before seating a new or indexed insert. Always index or replace all inserts in a multi-insert drill body at the same time to maintain balanced cutting loads.
