Iscar 3323749 Replaceable-tip Drill 0.374-0.39in 1/2in Shank

Product Description

The ISCAR 3323749 is a SumoCham-series replaceable-tip drill designed for precision holemaking in metal cutting applications. The DCN-style toolholder accepts FCP, HCP-IQ, ICK, ICK-2M, ICM, ICP, iCP-2M, and QCP-2M insert styles at a size-9 seat, allowing fast tip swaps without removing the body from the spindle. The drill covers a diameter range of 0.374 to 0.39 inches, reaches a maximum depth of 4.56 inches, and carries a 12xD depth-to-diameter ratio. Through-coolant delivery keeps cutting edges cool and flushes chips out of deep bores. Machinists and toolroom technicians running CNC machining centers will find this body suited to high-productivity deep-hole cycles.

This drill body is intended for use on CNC lathes, machining centers, and turret-style machines where a straight-cylindrical shank is the standard interface. The 0.5-inch shank fits directly into standard collet chucks, hydraulic chucks, or Weldon-style holders sized for 1/2-inch round shanks. With an overall length of 6.88 inches and a flute length of 4.56 inches, it handles through-hole and blind-hole work in steel, cast iron, and similar ferrous materials. The 12xD depth capability makes it a practical choice for deep-hole operations that would otherwise require peck cycles with shorter tooling.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before changing inserts or mounting the body, ensure the machine spindle is fully stopped and the control is in an e-stop or lockout-tagout state per shop safety procedures. Seat the shank fully into the holder and torque the clamping screw according to the holder manufacturer specification. Verify through-coolant passages are clear and unobstructed before starting a cutting cycle.
