Kennametal 1613627 Replaceable-tip Drill Weldon Flat

Product Description

The KENNAMETAL 1613627 is a replaceable-tip drill body designed for precision hole-making in metalworking applications. It accepts KSEM0641 series inserts at insert seat size 1, covering a drill diameter range of 16.28 to 16.78 mm (0.6409 to 0.6606 inches). The body features a 19.05 mm Weldon Flat shank for positive rotational drive in standard toolholders. Overall length is 142.88 mm (5.6252 inches), with a flute length of 68.07 mm (2.6799 inches) and a maximum drill depth of 52.07 mm (2.0500 inches), corresponding to a 3xD depth-to-diameter ratio. Through-coolant delivery is supported via 1/8-27 NPT coolant ports at both the shank end and body side. The body weighs 0.8818 pounds. This tool is installed and operated by machinists and CNC tooling specialists.

The 1613627 drill body is suited for production drilling in ferrous and non-ferrous metals where consistent hole geometry and extended tool life are required. The KSEM replaceable-tip system allows insert changes without removing the body from the spindle, reducing downtime in high-volume machining environments. The through-coolant capability supports elevated cutting speeds and chip evacuation in deep-hole drilling scenarios. It is commonly used in CNC machining centers and drill presses configured for Weldon Flat shank toolholders.

Installation Notes

Installation and insert changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, tagged-out state per applicable safety procedures. Confirm the toolholder is rated for the 19.05 mm Weldon Flat shank diameter before mounting. Coolant supply lines should be connected to the appropriate NPT ports using fittings compatible with 1/8-27 NPT thread. Inspect the insert seat and clamping surfaces for debris or damage before seating a new KSEM0641 insert.
