Kennametal 7034248 Dfpr Carbide Indexable Drill Insert

Product Description

The KENNAMETAL 7034248 is a DFPR-style indexable drill insert designed for use in Drill Fix series indexable drilling systems. Manufactured from carbide in the KCU40 grade and finished with a TiN coating, this insert delivers consistent cutting performance in demanding metal-removal applications. It features a 0.37-inch (9.40 mm) inscribed circle, a 3.00 mm thickness, and an 11-degree relief angle. The right-hand cutting orientation and LC chipbreaker geometry make it suited for controlled chip evacuation during through-hole and blind-hole drilling operations. Installation and replacement are performed by licensed machinists and tooling technicians on CNC and conventional drilling platforms.

This insert is intended for use in DFPR-compatible indexable drill bodies from the Drill Fix series. It is a size-09 insert with a 0.019-inch (0.50 mm) corner radius, designed for precision drilling in ferrous and non-ferrous materials. Typical applications include production drilling in manufacturing environments where insert indexability reduces downtime and maintains consistent hole quality across high-volume runs. The ANSI and ISO code for this insert is DFPR090305LCO.

Key Features

• DFPR insert style with proprietary shape geometry for Drill Fix series drill bodies
• KCU40 carbide grade with TiN coating for wear resistance in metal drilling
• LC chipbreaker for controlled chip formation and evacuation
• 11-degree relief angle reduces cutting forces and heat buildup at the cutting edge
• Right-hand cutting orientation; size-09 insert classification
• ANSI/ISO code DFPR090305LCO for direct cross-reference and sourcing

Compatibility

Designed for use with DFPR-compatible Drill Fix series indexable drill bodies requiring a size-09 insert. Compatible drill style is DFPR as specified by the manufacturer.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power locked out per facility LOTO procedures. Use the appropriate torx or insert-clamping tool specified by the drill body manufacturer to seat and torque the insert clamp. Inspect the insert pocket for damage or debris before seating the new insert. Do not force the insert into the pocket, as improper seating can cause insert failure or damage to the drill body.
