Ingersoll Cutting Tools 6181230 Replaceable-tip Drill 8xd

Product Description

The INGERSOLL CUTTING TOOLS 6181230 is a replaceable-tip drill body designed for high-productivity drilling operations in metal cutting applications. Built on the TD series platform, this drill body accepts TKA, TMA, TNA, TPA, TPC, and TPF insert styles at seat size 16, giving shops flexibility across a range of insert geometries. The tool covers a drilling diameter range of 0.6299 to 0.6654 inches with a maximum drilling depth of 5.04 inches at an 8xD depth-to-diameter ratio. Through-coolant capability is built in, supporting extended tool life and chip evacuation in deep-hole applications. The steel body weighs 0.38 pounds and measures 7.644 inches overall length.

This drill body is suited for production machining environments where frequent tip replacement is preferred over regrinding solid drills. The 8xD depth ratio makes it appropriate for deep-hole drilling in workpiece materials common in aerospace, automotive, and general metalworking. The 3/4 inch Weldon Flat shank with a 1.97 inch shank length provides positive drive and is compatible with standard Weldon-style toolholders. Right-hand cutting direction is standard. Through-coolant delivery supports consistent performance in interrupted cuts and materials prone to built-up edge.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the machine is locked out before changing inserts or mounting the drill body. Verify the Weldon Flat shank is fully seated and the set screw is torqued per the toolholder manufacturer specification before beginning a cut. Confirm through-coolant connections are engaged and flowing at adequate pressure before running deep-hole cycles.
