Seco 02445836 Replaceable-tip Drill 12.5-12.99mm Weldon

Product Description

The SECO 02445836 is a replaceable-tip drill designed for precision holemaking in metalworking and machining applications. Part of the CROWNLOC series, it accepts tip diameters ranging from 12.5 mm to 12.99 mm (0.4921 to 0.5114 inches) and delivers a maximum drill depth of 65 mm (2.5591 inches), providing a 5xD depth-to-diameter ratio. The drill features a 5/8 inch Weldon Flat shank for secure tool holding, a TiAlN coating for heat and wear resistance, and through-coolant capability to aid chip evacuation and extend tool life. Weighing 0.4 pounds, this tool is intended for use by machinists and CNC operators in production environments.

The SECO 02445836 is suited for holemaking operations on CNC machining centers and milling machines where replaceable-tip drills offer a cost-effective alternative to solid-carbide drills. The Weldon Flat shank is compatible with SD105-style toolholders, making it a practical fit for shops running standard modular tooling setups. Through-coolant delivery helps manage heat and chips in medium-to-deep hole drilling, particularly in steel and ferrous materials where TiAlN coatings perform best. This is a single-piece unit packaged individually.

Compatibility

Designed for use with SD105-style toolholders. Shank diameter is 5/8 inch (0.6250 inches) Weldon Flat. Suitable for machining centers and milling machines equipped for through-spindle coolant delivery.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Always ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body or replaceable tip. Verify the Weldon Flat shank is fully seated in the toolholder and that set screws are tightened against the flat per the toolholder manufacturer specifications. Confirm coolant channels are clear and through-coolant pressure is set appropriately for the operation before running the cycle.
