Kennametal 1713517 Indexable Drill Insert Dftmd KC7140

Product Description

The KENNAMETAL 1713517 is a solid carbide indexable drill insert designed for use in indexable drilling tools on CNC machining centers and lathes. Manufactured to the DFTMD insert style with a Trigon (84-degree included angle) shape, this insert carries the KC7140 grade designation and features a PVD-applied TiN and TiCN multilayer coating for heat resistance and edge durability. The inscribed circle measures 6 mm (0.2362 inches), thickness is 0.0965 inches, and the corner radius is 0.40 mm (0.0157 inches). The MD chipbreaker geometry supports chip control in a range of drilling applications across ferrous materials.

This insert is suited for precision drilling operations in production machining environments, including aerospace, automotive, and general metalworking applications. It fits indexable drill bodies that accept DFTMD-style Trigon inserts with a 6 mm inscribed circle and a 2.25 mm hole diameter. The KC7140 material grade (C5/C6) with PVD TiN/TiCN coating is commonly selected for machining steel and cast iron at moderate to high cutting speeds. Insert size designation is 030204.

Key Features

• Solid carbide construction with PVD-applied TiN and TiCN multilayer coating for extended tool life
• DFTMD insert style with Trigon shape and 84-degree included angle for indexable drill compatibility
• KC7140 grade (C5/C6 material grade) suited for steel and cast iron machining
• MD chipbreaker geometry promotes effective chip evacuation during drilling
• 6 mm inscribed circle (0.2362 inches) with 0.40 mm corner radius for precise fitment
• 8-degree relief angle supports clearance and reduces rubbing at the cutting edge

Compatibility

Designed for use in indexable drill bodies that accept DFTMD-style Trigon inserts with a 6 mm inscribed circle and insert size 030204. Verify tool body specifications before installation to confirm correct insert style and seating geometry.

Installation Notes

Indexable drill inserts of this type are installed and replaced by qualified machinists or tooling technicians. Power down and lock out the machine spindle before handling any cutting inserts. Use the appropriate torx or hex key torque driver per the drill body manufacturer's insert clamping specifications. Handle carbide inserts with care - edges are brittle and can chip if dropped or impacted.
