Kennametal 1798190 Replaceable-tip Drill 12.7-13.2mm

Product Description

The KENNAMETAL 1798190 is a replaceable-tip drill body engineered for precision hole-making in metal cutting applications. Designed around the KSEM platform, this drill body accepts KSEM0500 series inserts at an insert seat size C, allowing the cutting tip to be swapped without replacing the entire tool. The straight-cylindrical shank measures 19.05 mm in diameter, and the overall length runs 155.58 mm. With a 7xD depth-to-diameter ratio, the body supports a maximum drill depth of 88.9 mm. Through-coolant capability is built in, directing fluid directly to the cutting zone for improved chip evacuation and tool life in demanding production environments.

This drill body is suited for CNC machining centers and turning centers where repeatable, high-productivity drilling is required. The replaceable-tip design is common in production shops running high volumes of steel, cast iron, and similar ferrous workpiece materials where minimizing downtime on tool changes matters. The 12.7 to 13.2 mm diameter range and 88.9 mm maximum depth make it appropriate for medium-depth hole applications. Machinists and tool-and-die professionals are the primary end users, typically programming this tool into multi-pass drilling cycles where coolant-through capability is a process requirement.

Key Features

• Accepts KSEM0500 series replaceable tips at insert seat size C for fast tip changes without full tool replacement
• Through-coolant design channels fluid to the cutting edge for improved chip control and extended insert life
• 7xD depth-to-diameter ratio supports drilling to 88.9 mm maximum depth
• Straight-cylindrical shank at 19.05 mm diameter for broad machine compatibility
• Flute length of 101.85 mm provides adequate chip clearance over the full drilling depth
• Part of the KSEM series platform, supporting consistent insert inventory across multiple drill sizes

Compatibility

Designed for use with KSEM0500 series replaceable drill tip inserts at insert seat size C within the KENNAMETAL KSEM drill body platform.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per facility lockout/tagout procedures. Ensure the shank seating surface and spindle bore are clean and free of chips before mounting. Coolant-through connections must be properly sealed and verified before running to prevent pressure loss at the cutting zone. Follow the insert manufacturer torque specifications for the tip-locking screw when installing KSEM0500 series replaceable tips.
