Kennametal 1519230 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 1519230 is a replaceable-tip drill body in the KSEM series, designed for precision hole-making in metalworking and machining applications. It accepts KSEM0688 insert tips at an insert seat size of 1, allowing the cutting tip to be swapped without replacing the entire body. The drill covers a diameter range of 17.46 to 17.96 mm (0.6874 to 0.7071 inches) and reaches a maximum drilling depth of 126 mm (4.96 inches). Through-coolant capability is built in via a 3.50 mm (0.1378 inch) coolant hole, supporting chip evacuation and tool life in high-feed operations. The straight-cylindrical shank measures 19.05 mm in diameter and fits standard toolholders used by machinists and CNC operators in production environments.

This drill body is suited for medium-to-deep hole drilling at a 7xD depth-to-diameter ratio, making it appropriate for production machining in job shops, aerospace component manufacturing, and general metalworking. The KSEM platform is engineered for steel, stainless, and cast iron applications where consistent hole quality and reduced tooling changeover time are priorities. The replaceable-tip design reduces per-hole tooling cost compared to solid carbide drills in high-volume runs.

Key Features

• Replaceable KSEM0688 insert tip - body can be reused across multiple insert changes
• Through-coolant design with 3.50 mm coolant hole for chip flushing and heat control
• 7xD depth-to-diameter ratio supports holes up to 126 mm deep
• Straight-cylindrical shank for compatibility with standard drill chucks and toolholders
• Insert seat size 1 for precise tip seating and repeatable runout

Compatibility

Designed for use with KSEM0688 replaceable insert tips, insert seat size 1, within the KENNAMETAL KSEM series platform.

Installation Notes

Installation is performed by machining professionals in CNC lathe or machining center setups. Secure the straight-cylindrical shank in a qualified toolholder to the appropriate clamping torque per the machine tool manufacturer guidelines before operation. Ensure through-coolant supply lines are connected and flow is verified before drilling to prevent tip overheating and premature wear. Inspect the insert seat for debris or damage each time the tip is replaced to maintain dimensional accuracy.
