Kennametal 1329737 Replaceable-tip Drill 16.67-17.17mm

Product Description

The KENNAMETAL 1329737 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. It accepts KSEM0656 insert tips at an Insert Seat Size 1 and delivers a 5xD depth-to-diameter ratio, supporting a maximum drill depth of 90 mm (3.54 inches). The drill body features a straight-cylindrical shank measuring 19.05 mm in diameter and an overall length of 165.1 mm (6.5 inches). Through-coolant capability is built in via a 3.50 mm coolant hole, enabling effective chip evacuation and thermal management at the cutting zone. This tool is installed by machinists and CNC operators in production and job-shop environments.

The 1329737 is part of the KENNAMETAL KSEM series and is suited for drilling operations on steel, cast iron, and similar ferrous workpiece materials in both horizontal and vertical machining center setups. The body accommodates drill diameters ranging from 16.67 mm to 17.17 mm (0.6563 to 0.6760 inches), giving operators flexibility across close-tolerance bore requirements. The 110.28 mm flute length and 50.80 mm shank length support stable clamping and effective coolant delivery throughout the full drilling depth.

Installation Notes

Installation and insert changes should be performed by a qualified machinist with the machine powered off and the spindle fully stopped. Verify that the machine spindle bore and clamping system are sized for a 19.05 mm straight-cylindrical shank before mounting. Confirm coolant supply lines are open and delivering adequate pressure through the spindle before beginning any drilling cycle. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting depth stops and feed rates.
