Kennametal 5588937 Indexable Drill Insert Dftmd KC7140

Product Description

The KENNAMETAL 5588937 is a trigon-style indexable drill insert designed for use in indexable insert drills in metalworking and machining operations. Built from carbide substrate with a PVD-applied TiN coating, the insert delivers consistent cutting performance in a range of ferrous and non-ferrous materials. The MD chipbreaker geometry promotes controlled chip evacuation, reducing the risk of chip packing in deep-hole drilling applications. With an inscribed circle of 0.6930 inches (17.60 mm), an included angle of 84 degrees, and a corner radius of 1.20 mm, this insert is matched to precision toolholder systems where dimensional accuracy and repeatability are required.

This insert is suited for production drilling in machining centers, CNC lathes, and turning centers where indexable drill bodies using the DFT insert style are employed. Typical applications include through-hole and blind-hole drilling in steel, cast iron, and similar materials in industrial and job-shop environments. The TiN PVD coating extends tool life by reducing friction and wear at the cutting edge. Licensed machinists and CNC operators performing high-volume hole-making operations are the primary installers and users of this insert. Insert size designation is 110508, and the hole diameter is 0.2300 inches (5.85 mm).

Key Features

• 84-degree included angle trigon geometry for DFT-style insert drill bodies
• Inscribed circle of 0.6930 inches (17.60 mm) for precise seat engagement
• Corner radius of 1.20 mm reduces edge chipping at drill entry and exit
• Insert size 110508 with 0.2300-inch mounting hole diameter

Compatibility

Designed for use in indexable drill bodies that accept DFT-style trigon inserts with an insert size designation of 110508. Consult the toolholder manufacturer specifications to confirm seat geometry and clamping compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Seat contact surfaces on the drill body should be inspected and cleaned before seating a new insert to ensure proper clamping and runout. Follow the toolholder manufacturer torque guidelines for the clamping screw; use the correct Torx or hex key as specified by the toolholder.
