Sandvik Coromant 7357714 Replaceable Drill Tip 14mm

Product Description

The SANDVIK COROMANT 7357714 is a replaceable drill tip designed for use with CoroDrill 870 modular drilling systems. It features a 14.00 mm (0.5512 inches) cutting diameter, a 142-degree drill point angle, and is manufactured from solid carbide with a fine grain material grade. The AlTiCrN coating is applied via PVD process, improving wear resistance and thermal stability during cutting. This tip uses a KM insert geometry and is held by a clamp mechanism. It is intended for professional machining environments where consistent hole quality and repeatable tip changes are required.

This drill tip is suited for solid drilling applications in steel and cast iron workpieces, corresponding to ISO material groups P and K. The CoroDrill 870 system is commonly used in CNC machining centers for production drilling where tip replacement — rather than full tool replacement — reduces tooling costs and downtime. The helical flute design with regular spiral promotes chip evacuation during through and blind hole drilling operations. Seat size 14 matches the corresponding CoroDrill 870 body. Typical users include CNC machinists and toolroom technicians in metalworking and manufacturing environments.

Key Features

• 14.00 mm cutting diameter with 142-degree standard point angle
• Solid carbide construction with fine grain grade 3334 for wear resistance
• AlTiCrN coating via PVD process for thermal and oxidation resistance
• KM insert geometry compatible with CoroDrill 870 seat size 14 bodies
• Helical flutes with regular spiral for efficient chip evacuation
• Clamp-held interface for secure, repeatable tip indexing

Compatibility

Designed for use with CoroDrill 870 modular drill bodies requiring insert seat size 14. ISO number 870-1400-14-KM 3334. Optimized for drilling steel and cast iron (ISO material groups P and K).

Installation Notes

Installation and tip changes are typically performed by CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool is secured before removing or seating the drill tip. The clamp holding method requires proper torque applied with the correct Torx or hex key as specified by the tool body documentation — do not overtighten or substitute fasteners. Inspect the seat surface for chips or debris before seating a new tip to maintain runout accuracy.
