Kennametal 1925976 Indexable Drill Insert Dfthd KC7215

Product Description

The KENNAMETAL 1925976 is a solid carbide indexable drill insert designed for use in indexable drilling operations requiring tight tolerances and reliable edge performance. Carrying the DFTHD designation, it features an 84-degree trigon shape with a KC7215 manufacturer grade and a TiAlN coating applied via PVD process. The inscribed circle measures 17.60 mm (0.6929 inches), with a corner radius of 0.60 mm (0.0236 inches) and a thickness of 0.1941 inches. The HD chipbreaker geometry helps manage chip evacuation in demanding drilling applications. This insert is sized at ISO insert size 110506 and weighs approximately 0.0446 pounds.

This insert is suited for metalcutting drilling operations where carbide grades C3, C4, and C7 material classifications apply, covering a range of ferrous and non-ferrous workpiece materials. The TiAlN PVD coating enhances wear resistance and thermal stability at the cutting edge, making it appropriate for production drilling in machining centers and CNC drill presses. Machinists and toolroom technicians working in job shop or production environments will find this insert compatible with DFTHD-style indexable drill bodies requiring a trigon insert geometry.

Key Features

• 84-degree trigon insert shape with DFTHD style designation
• KC7215 grade solid carbide with TiAlN PVD coating for wear and heat resistance
• HD chipbreaker geometry for controlled chip formation during drilling
• Inscribed circle of 17.60 mm (0.6929 inches) and corner radius of 0.60 mm
• Relief angle of 8 degrees for reduced cutting forces
• Mounting hole diameter of 5.85 mm (0.2303 inches) for positive insert seating

Compatibility

Designed for use in DFTHD-style indexable drill bodies requiring an 84-degree trigon insert at ISO insert size 110506. Confirm toolholder pocket geometry and seating dimensions before installation.

Installation Notes

Insert seating and torque should follow the toolholder manufacturer specifications for the mating drill body. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key as specified by the toolholder to avoid stripping the insert screw. Inspect the pocket seat for chips or wear before installing a new insert.
