Kennametal 3884452 Carbide Replaceable Tip Drill 26mm KC7410

Product Description

The KENNAMETAL 3884452 is a KSEM-series carbide replaceable tip drill designed for high-productivity hole-making in metalworking applications. The drill features a solid carbide tip in grade KC7410 with an AlCr PVD coating, a 140-degree drill point angle, and an HPCCL insert geometry. At 26mm (1.0236 inches) cutting diameter, it accepts an insert seat size 5 and uses a clamp-style holding method to secure the tip. The helical flute design with a regular spiral and 2-flute, 2-margin configuration promotes chip evacuation and dimensional accuracy. Licensed machinists and CNC operators install this drill in machining centers and drill presses for precise, repeatable bore work.

The KENNAMETAL 3884452 is suited for drilling operations in a wide range of metallic workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, corresponding to ISO material groups P, M, K, N, and S. Typical applications include straight drilling, inclined-exit drilling, and stacked-plate drilling. The KSEM replaceable tip platform allows quick tip changes at the machine without removing the drill body, reducing downtime in production environments. This drill is intended for use in professional CNC and conventional machining setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is locked out before tip replacement. Use the appropriate torx or hex key as specified by the KSEM toolholder documentation to tighten the clamp to the manufacturer-specified procedure. Verify tip seating and runout before commencing cutting operations.
