Kennametal 1279864 Replaceable-tip Drill 19-19.5mm

Product Description

The KENNAMETAL 1279864 is a replaceable-tip drill body engineered for precision hole-making in metalworking applications. It accepts KSEM1900 series inserts at an insert seat size 2, allowing the cutting tip to be swapped without removing the drill body from the spindle. The shank is a 25 mm whistle notch design, and the tool delivers a maximum drill depth of 140 mm at a 7xD depth-to-diameter ratio. Through-coolant is supported via a 3.50 mm coolant hole, keeping the cutting zone clear of chips and controlling heat at depth. This tool is intended for use by machinists and tooling specialists in CNC machining centers and drill presses.

This drill body is suited for production drilling in ferrous and non-ferrous materials where consistent hole quality and fast insert indexing are required. The KSEM platform is designed for high-volume drilling operations in job shop and manufacturing environments. The 25 mm whistle notch shank provides positive drive and rotational security in compatible tool holders. The 224 mm overall length and 163 mm flute length accommodate setups requiring extended reach without sacrificing rigidity.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for whistle notch shank retention and torque. Verify spindle and tool holder compatibility with the 25 mm shank diameter before mounting. Confirm through-coolant passages are clear and coolant supply is connected before beginning any drilling cycle. Follow safe lockout and energy isolation procedures when changing inserts or setting tool offsets.
