Seco 02445840 Replaceable-tip Drill 16-16.99mm Weldon

Product Description

The SECO 02445840 is a replaceable-tip drill designed for precision holemaking in metal fabrication and machining applications. It accepts SD100-style inserts and is built on the SD105 toolholder platform, providing a reliable, modular cutting solution. The drill covers a diameter range of 16 to 16.99 mm (0.6299 to 0.6689 inches) and reaches a maximum drill depth of 3.15 inches, with a depth-to-diameter ratio of 5xD. A 5/8-inch Weldon Flat shank ensures positive drive and minimal runout in compatible tool holders. Through-coolant capability supports chip evacuation and extended insert life during deep-hole operations.

This drill is suited for production and job-shop environments where repeatable hole quality and fast insert changes are required. The replaceable-tip design eliminates the need to replace the entire drill body when the cutting edge wears, reducing tooling cost per hole. Typical applications include structural steel, alloy steel, and cast iron holemaking on CNC machining centers and drill presses equipped with through-coolant capability. The SD105 series is a common choice for shops running moderate-to-high volume drilling cycles where insert indexability and consistent diameter hold tolerance are priorities.

Key Features

• Replaceable SD100 insert tip — change inserts without removing the drill body from the machine
• Through-coolant design for effective chip flushing and heat management at depth
• 5/8-inch Weldon Flat shank provides positive rotational drive and easy tool-holder seating
• 5xD depth-to-diameter ratio supports deeper holes in a single pass
• Overall length of 6.26 inches accommodates standard machining center spindle clearance
• Conforms to ISO 9766 standards for modular drill body geometry

Compatibility

Designed for use with SD100-style replaceable drill inserts in the SD105 toolholder series. Requires a tool holder or spindle accepting a 5/8-inch Weldon Flat shank with through-coolant delivery for full performance.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the drill body or insert. Verify that the Weldon Flat set screw in the tool holder is properly torqued per the tool holder manufacturer specification before running. Confirm through-coolant pressure and flow rate are within the insert manufacturer recommendations prior to engaging the cut.
