Kennametal 1519277 Replaceable-tip Drill Ksem 25.4mm

Product Description

The KENNAMETAL 1519277 is a replaceable-tip drill body in the KSEM series, designed for high-productivity hole-making in metalworking applications. The drill body accepts KSEM1000 insert tips at Insert Seat Size 5, allowing worn or damaged cutting tips to be swapped without replacing the entire tool. The straight-cylindrical shank measures 25.4 mm in diameter, and the overall length is 295.28 mm. Maximum drill depth reaches 182 mm, yielding a depth-to-diameter ratio of 7xD. Through-coolant delivery is supported via a 4 mm coolant hole diameter, helping to evacuate chips and control heat at the cutting zone. This tool is typically installed by CNC machinists and toolroom technicians on machining centers and CNC lathes configured for through-spindle coolant.

The 1519277 drill body covers a diameter range of 25.4 mm to 25.9 mm, accommodating different KSEM1000 tip sizes within that window. It is suited for production drilling in steel, cast iron, and similar materials where consistent hole quality and extended tool life are required. The 7xD depth capability makes it appropriate for deep-hole applications such as hydraulic manifolds, structural components, and mechanical housings where a single-pass approach is preferred over step drilling. The tool is part of the broader KSEM platform, which standardizes shank bodies and replaceable tips across a range of diameters.

Key Features

• Replaceable KSEM1000 insert tip system at Insert Seat Size 5 reduces tooling cost per hole
• 7xD depth-to-diameter ratio supports drilling up to 182 mm deep in a single setup
• Through-coolant design with 4 mm coolant holes promotes chip evacuation and thermal control
• Straight-cylindrical 25.4 mm shank for compatibility with standard ER and hydraulic toolholders
• Flute length of 215.06 mm provides adequate chip clearance through the full depth range
• Part of the standardized KSEM series platform for consistent insert and body interchangeability

Compatibility

Designed for use with KSEM1000 series replaceable tips at Insert Seat Size 5. Compatible with machine spindles and toolholders accepting a 25.4 mm straight-cylindrical shank. Part of the KSEM series platform.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle and coolant supply are fully de-energized and locked out before mounting or removing the drill body. Confirm that the toolholder bore is clean and free of debris before inserting the shank, and verify through-coolant passages are clear and unobstructed before operation. Follow the machine tool manufacturer and KENNAMETAL application guidelines for feed rate and spindle speed selection appropriate to the workpiece material.
