Kennametal 1329355 Replaceable-tip Drill 22.23-22.73mm

Product Description

The KENNAMETAL 1329355 is a replaceable-tip drill body engineered for precision hole-making in metal cutting applications. Part of the KSEM series, this drill accepts KSEM0875 insert tips at an insert seat size 4, allowing the body to be reused while only the cutting tip is replaced. The straight-cylindrical shank measures 31.75 mm in diameter, and the tool reaches an overall length of 234.95 mm. It supports a maximum drill depth of 120 mm at a 5xD depth-to-diameter ratio. Through-coolant capability is built in via a 3.50 mm coolant hole, delivering fluid directly to the cutting zone to manage heat and chip evacuation during deep-hole drilling operations.

This drill body is suited for production machining environments where consistent hole diameter and depth are critical. It covers a drill diameter range of 22.23 to 22.73 mm, making it appropriate for applications requiring close-tolerance bores in that size range. Typical use cases include CNC machining centers performing structural component drilling in aerospace, automotive, and general metalworking. The replaceable-tip design reduces tooling cost per hole by eliminating the need to replace the full drill body when the cutting edge wears. Machinists and tooling specialists working in job shops or production lines will find this format practical for high-volume runs.

Key Features

• Replaceable-tip design accepts KSEM0875 inserts, insert seat size 4
• Through-coolant delivery via 3.50 mm coolant hole for heat and chip control
• 5xD depth-to-diameter ratio supports drilling to 120 mm maximum depth
• Straight-cylindrical shank at 31.75 mm diameter for standard toolholder compatibility
• Flute length of 148.38 mm provides extended chip clearance
• Part of the KSEM series for consistent insert and body interchangeability

Compatibility

Designed for use with KSEM0875 replaceable drill tip inserts at insert seat size 4, within the KENNAMETAL KSEM series system. Drill diameter range of 22.23 to 22.73 mm applies based on insert selection within the compatible tip family.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle and toolholder are powered down and at a complete stop before seating or removing the insert tip. Use the correct torque driver and seating procedure specified by KENNAMETAL for KSEM series insert installation — do not overtighten by hand estimation. Verify through-coolant passages are clear and that the toolholder provides adequate coolant pressure before beginning the drilling cycle.
