Ingersoll Cutting Tools 3204630 Replaceable-tip Drill

Product Description

The INGERSOLL CUTTING TOOLS 3204630 is a replaceable-tip drill body engineered for precision hole-making in metalworking applications. Built on the TD series platform, it accepts TKA, TMA, TNA, TPA, TPC, and TPF insert styles at a seat size of 7.5, allowing the operator to swap worn tips without replacing the entire tool body. The shank measures 0.5 inches in diameter with a Weldon flat profile for positive rotational drive in standard toolholders. Through-coolant capability channels fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep-hole operations. The body is constructed from steel with a PVD coating classification and cuts in a right-hand direction.

This drill body is suited for production drilling in CNC machining centers and turning centers where repeatable hole geometry and fast tip changes are priorities. The 5xD depth-to-diameter ratio supports drilling to a maximum depth of 1.48 inches within the 0.2953 to 0.311 inch diameter range. It is used by machinists and tool-and-die professionals working in job shops, aerospace component manufacturing, and general metal fabrication. The Weldon flat shank ensures secure seating in side-lock holders, reducing pullout risk during aggressive feed rates.

Compatibility

Compatible insert styles include TKA, TMA, TNA, TPA, TPC, and TPF at insert seat size 7.5. Designed for use with TD series toolholders accepting a 0.5 inch Weldon flat shank.

Installation Notes

Installation and insert changes should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per applicable safety procedures. Confirm the side-lock holder set screw engages the Weldon flat fully before running at speed. Verify through-coolant connections are clear and delivering adequate flow before beginning a drilling cycle. Follow the insert manufacturer's recommended torque procedure when seating replaceable tips to avoid seat damage.
