Kennametal 1729874 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 1729874 is a KSEM-series replaceable-tip drill body designed for deep-hole drilling in metal-cutting applications. It accepts KSEM0625 insert tips at a size-1 seat and supports a minimum drill diameter of 15.88 mm and a maximum of 16.38 mm. Maximum drill depth reaches 158.75 mm, representing a 10xD depth-to-diameter ratio. The straight-cylindrical shank measures 19.05 mm in diameter. Overall length is 228.6 mm. The body features internal coolant holes with a diameter of 3.50 mm to direct cutting fluid directly to the cutting zone. Licensed machinists and CNC operators use this tool in production turning and machining centers.

This drill body suits medium-to-high volume production environments where replaceable-tip tooling reduces downtime versus brazed or solid carbide alternatives. It is sized for workpieces requiring precise bores in the 15.88 to 16.38 mm range and a depth capacity from 125.00 mm to 160.00 mm. The KSEM platform is commonly applied in ferrous and non-ferrous metal machining on CNC vertical and horizontal machining centers where consistent hole geometry and tool life are critical.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician. Ensure the machine spindle and tool holder are powered down and locked out before loading or removing the drill body. Verify the straight-cylindrical shank is fully seated and clamped to the tool holder manufacturer torque specifications before operation. Always confirm insert tip seating and screw torque before the first cutting pass.
