Kennametal 1713515 Indexable Drill Insert Dftmd KC7140

Product Description

The KENNAMETAL 1713515 is a solid carbide indexable drill insert designed for use in indexable drilling operations on CNC machining centers and drill press setups. Carrying the KC7140 manufacturer grade with a PVD-applied TiN and TiCN coating, this insert delivers hard, wear-resistant cutting edges suited to steel and cast iron applications in the C5 and C6 material grade range. The trigon (84-degree included angle) geometry with an MD chipbreaker promotes controlled chip evacuation in through-hole and blind-hole drilling. The 6 mm inscribed circle and 0.40 mm corner radius position it for small-diameter drilling applications where dimensional consistency is critical. Installed by machinists and tool-setup technicians, this insert seats into compatible KENNAMETAL indexable drill bodies.

This insert is intended for indexable drill tooling systems that accept the DFT insert style with a 030304 insert size designation. Typical applications include production drilling in steel, alloy steel, and cast iron workpieces in job shops, aerospace component machining, and general metalworking environments. The MD chipbreaker geometry is optimized for medium-feed drilling conditions. Sold individually; the minimum order quantity is 10 pieces per order.

Key Features

• KC7140 grade with PVD TiN and TiCN coating for wear resistance in steel and cast iron
• 84-degree trigon shape with MD chipbreaker for controlled chip flow
• 6 mm inscribed circle (0.2362 inches) for small-diameter drill body fitment
• 0.40 mm corner radius reduces edge chipping at drill entry and exit
• 8-degree relief angle supports positive cutting action and reduced thrust
• Insert size 030304 for precise seating in compatible drill bodies

Compatibility

Designed for use in indexable drill bodies that accept the DFT insert style in 030304 insert size. Confirm toolholder specifications against KENNAMETAL catalog data before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key as specified by the drill body manufacturer to achieve proper clamp torque — do not overtighten or use impact tools on insert screws. Inspect the insert pocket for debris or damage before seating a new insert to ensure full contact and accurate register.
