Ingersoll Cutting Tools 6181219 Replaceable-tip Drill

Product Description

The INGERSOLL CUTTING TOOLS 6181219 is a replaceable-tip drill designed for high-precision drilling operations in metal-cutting environments. It accepts TKA, TMA, TNA, TPA, TPC, and TPF insert styles in a seat size 14, giving machinists and tooling professionals the flexibility to swap cutting tips without replacing the entire body. The drill body is constructed from steel with a PVD coating classification and supports through-coolant delivery to manage heat and chip evacuation at the cut zone. It covers a diameter range of 0.5512 to 0.5669 inches and achieves a maximum drill depth of 2.76 inches, operating at a 5xD depth-to-diameter ratio.

This drill is suited for CNC machining centers and other machine tool setups where repeatable hole quality and insert economy are priorities. The Weldon flat shank with a 0.625-inch diameter provides positive drive and resists pullout under aggressive feed rates. Right-hand cutting direction is standard. Through-coolant capability makes it practical for deep-hole applications in steel, cast iron, and similar workpiece materials where chip packing and thermal buildup are common concerns. It is a Series TD toolholder-style drill intended for production and job-shop drilling applications.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and all motion has stopped before mounting or removing the drill body from the toolholder. Confirm the Weldon flat set screw is properly torqued to the machine tool manufacturer's specification before cutting. Verify through-coolant passages are clear and coolant pressure is within the machine's rated range before beginning the drilling cycle.
