Iscar 3202724 Replaceable-tip Drill Sumocham 8xd Through Coolant

Product Description

The ISCAR 3202724 is a replaceable-tip drill body in the SumoCham series, designed for high-performance holemaking in metalworking and machining applications. It accepts a range of interchangeable drill-tip inserts, allowing the drill body to be reused while only the cutting tip is replaced. The drill covers a diameter range of 0.709 to 0.744 inches, reaches a maximum drill depth of 5.67 inches at an 8xD depth-to-diameter ratio, and features through-coolant capability to manage heat and chip evacuation at depth. The overall length is 8.99 inches, with a straight-cylindrical shank measuring 1 inch in diameter. Licensed machinists and CNC toolroom technicians are the primary installers of this tooling.

This drill body is suited for production and job-shop environments where consistent bore quality and repeatable insert changes are required. It is used in vertical and horizontal machining centers as well as CNC lathes with driven tooling. The DCN toolholder-style body and ISO 13399 compliance make it straightforward to integrate into tool management and presetter systems. Through-coolant is particularly useful in deep-hole passes where chip packing and thermal buildup are concerns at the 8xD depth range.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. The machine spindle must be fully stopped and the tool path program must be verified before mounting this drill body into the toolholder. Ensure the shank bore and clamping surfaces are clean and free of chips before seating. Follow the insert manufacturer torque guidelines for the specific insert style when securing the replaceable tip, and verify runout with a dial indicator before production use.
