Seco 02445841 Replaceable-tip Drill 17-17.99mm Weldon Shank

Product Description

The SECO 02445841 is a replaceable-tip drill designed for precision holemaking in metal fabrication and machining environments. It accepts SD100-style inserts and is built on the SD105 toolholder platform, providing a modular system that reduces downtime when tips wear. The drill covers a diameter range of 17.00 to 17.99 mm (0.6693 to 0.7083 inches) with a maximum drill depth of 3.74 inches at a 5xD depth-to-diameter ratio. Through-coolant capability is standard, supporting chip evacuation and tool life in deeper hole applications. This tool is installed and operated by machinists and CNC setup technicians in production shop environments.

This drill is suited for holemaking operations in horizontal and vertical machining centers as well as CNC lathes equipped with live tooling. The 3/4-inch Weldon flat shank provides positive rotational drive and is compatible with standard Weldon-style toolholders. The 5xD depth-to-diameter ratio makes it appropriate for moderate-depth bores in steel, cast iron, and similar workpiece materials. Through-coolant delivery supports consistent chip clearing at full depth. The overall length of 6.957 inches accommodates typical spindle-to-workpiece clearances in production setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the spindle fully stopped and the machine in a locked-out state. Secure the shank in a Weldon-style holder and verify set screw engagement against the flat before operating. Confirm coolant through-port alignment before running at depth. Follow the toolholder manufacturer torque recommendations for set screw fastening.
