Kennametal 1330471 Replaceable-tip Drill 15.88-16.38mm

Product Description

The KENNAMETAL 1330471 is a replaceable-tip drill body engineered for precision hole-making in metalworking and machining applications. It accepts KSEM0625 series inserts at an insert seat size 1, covering a drill diameter range of 15.88 to 16.38 mm (0.6252 to 0.6449 inches). The straight-cylindrical shank measures 19.05 mm in diameter and 50.80 mm in length, while the overall length reaches 152.4 mm (6 inches). Through-coolant capability is built in via a 3.50 mm coolant hole, supporting effective chip evacuation and tool life in demanding cuts. Machinists and CNC operators rely on this body as part of the KSEM platform for high-productivity drilling.

This drill body is suited for use in CNC machining centers, lathes with live tooling, and manual milling setups where repeatable hole diameter and depth consistency are required. The 5xD depth-to-diameter ratio supports drilling up to 80 mm deep in a single pass, covering a maximum drill depth range of 80 to 100 mm. It is applicable across a wide range of workpiece materials depending on the insert grade selected. Industrial machinists and toolroom technicians working in production or job-shop environments are the primary installers.

Key Features

• Drill diameter range of 15.88 to 16.38 mm accommodates slight diameter variation through insert selection
• 5xD depth-to-diameter ratio allows drilling up to 80 mm deep in a single operation
• Through-coolant design with 3.50 mm coolant hole supports chip flushing and thermal management
• Straight-cylindrical shank at 19.05 mm diameter ensures compatibility with standard collet and chuck systems
• Replaceable-tip design reduces tooling cost by allowing insert swap without replacing the entire drill body
• Part of the KSEM series platform for consistent insert availability and seat repeatability

Compatibility

Designed for use with KSEM0625 series replaceable drill tip inserts at insert seat size 1. Compatible with standard machine tool spindles accepting a 19.05 mm straight-cylindrical shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and spindle locked. Ensure the shank bore and collet or chuck are clean and free of chips before seating the drill body. Torque the replaceable tip insert to the seat according to KENNAMETAL tooling documentation for the KSEM platform. Verify through-coolant connections are engaged and coolant pressure is appropriate for the application before initiating a cut.
