Kennametal 3381133 Ksem Carbide Replaceable Tip Drill 11/16

Product Description

The KENNAMETAL 3381133 is a solid carbide replaceable tip drill in the KSEM series, designed for high-performance hole-making in demanding metalworking applications. The drill accepts the KSEM0688HPL insert tip with an HPL geometry and a 140-degree included drill point angle, offering reliable centering and clean entry. The cutting diameter measures 11/16 inch (0.6874 inch / 17.46 mm). The tip uses a PVD-applied AlTiN coating and is manufactured from fine-grain solid carbide in the KCMS15 grade, giving it strong wear resistance at elevated cutting temperatures. This tool is intended for use in CNC machining centers and is installed and maintained by machinists and tooling specialists.

This drill is rated for use across a broad range of primary workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium — corresponding to ISO material groups P, M, K, N, and S. The KSEM system uses a clamp-style insert holding method to secure the replaceable carbide tip. The 2-flute, 2-margin helical flute design supports drilling of inclined exits and stacked plate applications in addition to standard through and blind hole drilling. The insert seat size is 1, and the flute length is 9.00 mm.

Key Features

• PVD AlTiN coating for thermal and wear resistance across hard and abrasive materials
• 140-degree standard drill point angle for accurate self-centering
• Fine-grain carbide substrate in manufacturer grade KCMS15
• Compatible with inclined exit, stacked plate, and standard drilling operations
• 2-flute, 2-margin regular helical spiral design for efficient chip evacuation

Compatibility

Designed as an OEM-style replaceable tip for KSEM series drill bodies accepting insert seat size 1. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium (ISO groups P, M, K, N, S).

Installation Notes

Installation and tip replacement should be performed by a qualified machinist familiar with KSEM-style clamping systems. Power down and lock out the machine spindle before seating or removing the replaceable tip insert. Use the correct torque tool for the clamp screw as specified in the KENNAMETAL KSEM tooling documentation — do not overtighten or substitute fasteners. Verify runout and tip seating before resuming cutting operations.
