Iscar 3201742 Replaceable-tip Drill Weldon Flat Shank

Product Description

The ISCAR 3201742 is a SumoCham-series replaceable-tip drill body designed for precision holemaking in metalworking applications. The drill body accepts interchangeable cutting tips, allowing worn inserts to be swapped out without replacing the full tool. It covers a diameter range of 0.906 to 0.941 inches and reaches a maximum drill depth of 4.53 inches, achieving a 5xD depth-to-diameter ratio. The 1-1/4-inch Weldon flat shank provides a secure, non-slip connection in compatible tool holders. Through-coolant capability delivers cutting fluid directly to the cutting zone, extending insert life and improving chip evacuation. This tool is installed and operated by machinists and CNC setup technicians in production and job-shop environments.

The 3201742 drill body is suited for holemaking operations on machining centers and CNC lathes where repeatable hole quality and fast insert changeout are priorities. The DCN toolholder-style body with an 8.32-inch overall length and a 5.96-inch body length accommodates a range of fixturing setups. The Weldon flat shank diameter of 1.25 inches fits standard side-lock holders. Compatible insert styles include FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M, giving operators flexibility in selecting cutting geometry for specific materials and finishes.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine in a fully powered-off and locked-out state per applicable LOTO procedures. Ensure the side-lock set screw engages the Weldon flat fully before operating. Flush the through-coolant passages before first use to confirm flow is unobstructed. Follow the insert manufacturer torque guidelines for the specific tip style selected when seating replaceable tips.
