Seco 02445834 Replaceable-tip Drill SD103 19-19.99mm

Product Description

The SECO 02445834 is a replaceable-tip drill in the SD103 series, designed for precision holemaking in metal and industrial machining applications. It accepts SD100 insert tips and features through-coolant capability to manage heat and chip evacuation at the cutting zone. The drill covers a diameter range of 19 to 19.99 mm (0.7480 to 0.7870 inch decimal) with a maximum drill depth of 2.36 inches, following a 3xD depth-to-diameter ratio. The 3/4 inch Weldon flat shank provides positive drive and resists pullout in high-feed operations. Overall length is 5.61 inches. This tool is installed and operated by machinists and tooling technicians in production and job-shop environments.

The 02445834 is suited for holemaking operations on machining centers and drill presses where consistent hole diameter and depth control are required. The replaceable-tip design reduces downtime compared to solid carbide drills — when the cutting edge wears, only the SD100 insert is swapped, not the full tool body. Through-coolant delivery makes it effective in deep drilling passes where chip packing and thermal buildup are common concerns. Typical applications include structural steel fabrication, general machining, and production drilling of medium to large diameter holes.

Key Features

• Diameter range: 19 to 19.99 mm (0.7480 to 0.7870 inch) for flexible hole sizing within a single body
• Through-coolant design channels coolant directly to the cutting tip for heat control and chip flushing
• Compatible with SD100 replaceable insert tips, reducing tooling cost versus full solid-body replacement
• 3xD drill depth-to-diameter ratio with a maximum drill depth of 2.36 inches
• 3/4 inch Weldon flat shank for positive rotational engagement and secure clamping
• Meets ISO 9766 standard for through-coolant tooling

Compatibility

Designed for use with SD100-style replaceable insert tips. The tool body is part of the SD103 series and is intended for use in holders and spindles accepting a 3/4 inch Weldon flat shank.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine spindle fully stopped and the machine in a locked-out, de-energized state. Ensure the Weldon flat on the shank is properly aligned with the set screw in the toolholder before torquing to the holder manufacturer's specification. Verify coolant supply lines are active and flowing before beginning a drilling cycle to protect the insert tip. Follow the insert manufacturer's seating procedure when replacing SD100 tips to ensure proper tip registration and runout.
