Seco 02445832 Replaceable-tip Drill 17-17.99mm Weldon

Product Description

The SECO 02445832 is a replaceable-tip drill designed for precision holemaking in metal cutting applications. Built on the SD103 platform, it accepts SD100-style inserts, allowing tip replacement without removing the holder from the machine. The drill covers a diameter range of 17 to 17.99 mm (0.6693 to 0.7083 inches) and reaches a maximum drill depth of 2.36 inches at a 3xD depth-to-diameter ratio. A 3/4-inch Weldon flat shank provides positive rotational engagement in compatible toolholders. Through-coolant capability channels cutting fluid directly to the cutting zone for improved chip evacuation and thermal control. Overall length is 5.539 inches.

This drill is suited for production drilling in steel, cast iron, and similar materials where repeatable hole quality and fast insert changes are priorities. The replaceable-tip design reduces tooling cost per hole by allowing the carbide tip to be swapped at the machine without replacing the full drill body. Typical applications include CNC machining centers and drill presses running ISO-standard toolholding setups. The SD103 series is commonly used in high-volume manufacturing and job shop environments where cycle time and consistency matter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool is properly secured in a compatible Weldon flat toolholder before operation. Verify insert seating and locking screw torque per the insert manufacturer guidelines before engaging the workpiece. Through-coolant passages should be cleared of obstructions before use to maintain effective chip evacuation.
