Seco 02445833 Replaceable-tip Drill 18-18.99mm Weldon Shank

Product Description

The SECO 02445833 is a replaceable-tip drill designed for precision holemaking in metal cutting applications. It accepts SD100 insert tips and belongs to the SD103 series, giving machinists a rigid, repeatable drilling platform without the cost of solid carbide. The drill covers a diameter range of 18.00 to 18.99 mm (0.7087 to 0.7476 inches), reaches a maximum drill depth of 2.36 inches at a 3xD depth-to-diameter ratio, and features a 3/4-inch Weldon flat shank for positive drive in standard milling-style tool holders. Through-coolant capability directs cutting fluid directly to the cutting edge for improved chip evacuation and tool life.

This drill is used in CNC machining centers, milling machines, and drill presses where consistent bore geometry and controlled depth are required. It is suited to production holemaking in steel, cast iron, and similar ferrous workpiece materials. The SD103 toolholder style and SD100 compatible insert system make it a common choice in job shop and production environments where operators need to swap worn tips quickly without replacing the entire drill body. The Weldon flat shank provides a secure, no-slip interface in set-screw-style tool holders. It meets ISO 9766 standards for replaceable-tip drilling tools.

Compatibility

Designed for use with SD100-style replaceable insert tips in SD103-series toolholders. Requires a 3/4-inch Weldon flat shank tool holder. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is locked out before mounting or removing the drill body or insert tip. Seat the Weldon flat shank fully into the holder and tighten the set screw to the tool holder manufacturer's specification. Verify insert seating and tip security before initiating a cut, and confirm coolant through-flow is active before running the drill at full feed and speed.
