Kennametal 1505183 Replaceable-tip Drill Weldon Flat

Product Description

The KENNAMETAL 1505183 is a replaceable-tip drill designed for precision hole-making in metal cutting applications. Part of the KSEM series, it accepts KSEM0938 inserts at an insert seat size 4, allowing tip replacement without discarding the drill body. The shank diameter measures 25.4 mm (approximately 1 inch) with a Weldon flat profile for secure toolholder engagement. Overall length is 244.48 mm (9.625 inches), with a flute length of 148.59 mm (5.85 inches). Through-coolant capability is supported via NPT-threaded coolant ports, making it suitable for high-speed, high-feed drilling where heat and chip evacuation are critical concerns. Machinists and tool-room professionals install this drill on CNC machining centers and turning centers.

This drill covers a diameter range of 23.81 to 24 mm (0.9374 to 0.9449 inches) and achieves a maximum drill depth of 120 mm (4.72 inches), representing a 5xD depth-to-diameter ratio. It is suited for production drilling operations in steel, cast iron, and similar ferrous materials where consistent bore diameter and repeatable positioning are required. The Weldon flat shank mates with standard Weldon-style toolholders commonly found in CNC vertical and horizontal machining centers.

Key Features

• Replaceable KSEM0938 insert tip eliminates full tool replacement at end of tip life
• Through-coolant design with NPT ports: 1/8-27 body side and 1/4-18 shank end
• 5xD depth-to-diameter ratio supports deep-hole drilling up to 120 mm
• Weldon flat shank provides positive drive and prevents rotation in the holder
• Insert seat size 4 for repeatable tip indexing and diameter accuracy
• KSEM series platform allows one body to run multiple compatible insert geometries

Compatibility

Designed for use with KSEM0938 series replaceable tips at insert seat size 4. Fits Weldon flat toolholders with a 25.4 mm bore diameter. Part of the KENNAMETAL KSEM modular drill platform.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts or mounting the drill body. Secure the Weldon flat shank in a properly sized toolholder and torque the set screw per the toolholder manufacturer specifications. Confirm through-coolant connections are clear and leak-free before initiating a cut, and verify drill depth and diameter offsets in the machine controller before the first pass.
