Sandvik Coromant 7357894 Replaceable Tip Drill 18mm Carbide

Product Description

The SANDVIK COROMANT 7357894 is a carbide replaceable tip drill designed for precision hole-making in metal cutting applications. Built on the CoroDrill 870 platform, this drill tip features a solid carbide construction with a TiAlN coating applied via PVD process, delivering heat and wear resistance during high-speed drilling. The 18mm cutting diameter and 142-degree included angle make it suited for through-hole and blind-hole operations in steel and similar materials. Machining professionals and toolroom technicians install this tip into compatible CoroDrill 870 holders as a consumable cutting component, separating tip replacement cost from the body investment.

This replaceable drill tip targets production machining environments where consistent hole quality and fast tip changeover are priorities. The PM insert geometry is optimized for controlled chip formation in a range of workpiece materials. Typical installations include CNC machining centers, horizontal boring mills, and similar machine tools where the CoroDrill 870 series holder is already in use. The tip is intended for single-use replacement cycles, allowing the holder body to remain in service while worn tips are swapped quickly without full drill replacement.

Key Features

• Solid carbide construction for rigidity and wear life in metal cutting
• TiAlN coating via PVD process for elevated heat resistance and extended tool life
• 18mm cutting diameter with 0.7087 inch decimal equivalent for direct imperial reference
• 142-degree included angle suited for standard through-hole and blind-hole drilling
• PM insert geometry for predictable chip control
• CoroDrill 870 series platform enables fast tip-swap without removing the holder body

Compatibility

Designed for use with CoroDrill 870 series drill bodies accepting an 18mm insert seat size. Confirm holder insert seat size before ordering to ensure correct fit.

Installation Notes

Installation is performed by machining technicians familiar with indexable and replaceable-tip tooling systems. Power down and lock out the machine spindle before removing or seating the drill tip. Use the manufacturer-specified torque wrench and drive key for the locking screw to ensure proper tip seating. Inspect the insert pocket and seating surfaces for chips or damage before installing a new tip.
