Seco 02445835 Replaceable-tip Drill 12-12.49mm SD105

Product Description

The SECO 02445835 is a replaceable-tip drill body in the SD105 series, designed for precision holemaking in metal and industrial materials. It accepts SD100 insert tips and delivers consistent bore diameters from 12.00 mm to 12.49 mm (0.4724 to 0.4917 inches). The tool features through-coolant capability to evacuate chips and control heat at the cutting zone. The 5/8 inch Weldon Flat shank provides positive drive engagement in compatible toolholders. With an overall length of 5.551 inches and a maximum drill depth of 2.56 inches, this body suits production drilling setups requiring reliable depth-to-diameter performance at a 5xD ratio. Installation is handled by machinists and CNC tooling specialists.

The 02445835 is suited for CNC machining centers and manual drilling operations requiring repeatable hole tolerances in the 12 mm diameter range. The replaceable-tip design reduces tooling cost by allowing tip replacement without discarding the drill body. Through-coolant delivery makes it practical for deeper-hole applications where chip packing is a concern. The SD105 toolholder style is compatible with the SD100 insert family. This drill is a fit for job shops, production floors, and tool rooms performing holemaking operations on ferrous and non-ferrous workpieces.

Compatibility

Designed for use with SD100 series replaceable insert tips and SD105 series toolholders. Accepts inserts covering diameters from 12.00 mm to 12.49 mm.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts or mounting the drill body. Seat the Weldon Flat shank fully into the toolholder and torque the set screw per the toolholder manufacturer specification. Verify through-coolant passages are clear and coolant pressure is within the machine and insert manufacturer guidelines before beginning a cut.
