Kennametal 1804785 Indexable Drill Insert Kmf Carbide

Product Description

The KENNAMETAL 1804785 is a solid carbide indexable drill insert designed for use in indexable drilling operations on machining centers and CNC lathes. Manufactured to the DFTHP style with a KMF grade designation, this insert features an 84-degree trigon shape with a bright uncoated finish suited for applications where coating-free cutting edges are preferred. The inscribed circle measures 10 mm (0.3937 inches), the insert thickness is 0.1476 inches, and the corner radius is 0.80 mm (0.0315 inches). Carbide construction provides the hardness and thermal resistance needed for consistent performance in production drilling. Licensed machinists and tooling specialists typically source and install this insert.

This insert is applied in indexable drill bodies that accept DFTHP-style trigon inserts in the 06T308 insert size. It is suited for drilling ferrous and non-ferrous materials where a C2 to C6 material grade carbide is appropriate. The uncoated bright finish makes it a practical choice for materials that may react adversely to common coatings, or where a sharp, uncoated edge is required for chip formation. It fits standard indexable drill tooling systems that use 4.4 mm mounting hole diameter inserts with an 8-degree relief angle.

Compatibility

Designed as an OEM-style replacement indexable drill insert for tooling systems accepting DFTHP-style trigon inserts in the 06T308 insert size with a 4.4 mm hole diameter.

Installation Notes

Installation of indexable inserts should be performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key specified by the drill body manufacturer to achieve proper clamping torque — do not overtighten or undertighten the insert screw. Inspect the insert pocket for wear or debris before seating the new insert to ensure proper contact and runout.
