Sandvik Coromant 7357837 Drill Tip 17mm Grade 2334

Product Description

The SANDVIK COROMANT 7357837 is a replaceable drill tip designed for use with the CoroDrill 870 modular drilling system. Manufactured from solid carbide with a fine grain material grade, this tip features an AlTiCrN coating applied via PVD process for extended wear resistance in demanding cutting applications. The tip measures 0.6575 inches (16.70 mm) in cutting diameter with a 142-degree included point angle and an MM insert geometry. It is intended for licensed machinists and tooling specialists working in high-production drilling environments where repeatable accuracy and insert interchangeability are required.

This drill tip is engineered primarily for cutting stainless steel, superalloys, and titanium — material groups classified under ISO codes M and S. It fits into an insert seat size 16 holder and is secured by a clamp holding method. The CoroDrill 870 system is used in solid drilling applications on CNC machining centers and turning centers in both job shop and production environments. Its helical flute design and regular spiral type support chip evacuation during through-hole and blind-hole operations in tough workpiece materials.

Key Features

• Solid carbide construction with fine grain material grade for toughness and edge retention
• AlTiCrN coating via PVD process for heat and wear resistance in stainless steel and superalloy cutting
• 142-degree point angle with standard point type for accurate entry and reduced thrust force
• MM insert geometry with helical, regular spiral flutes for effective chip evacuation
• Insert seat size 16, clamp-held — direct fitment into compatible CoroDrill 870 holders
• Functional length of 0.2937 inches with an overall projection of 0.3937 inches

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 modular drill bodies that accept insert seat size 16 and MM geometry tips. ISO number 870-1670-16-MM 2334 identifies direct holder compatibility within the CoroDrill 870 system.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with the CoroDrill 870 modular system. Before changing the drill tip, the machine spindle must be fully stopped and locked out per facility lockout/tagout procedures. The tip is seated and clamped using the appropriate torx or hex key as specified by the holder documentation — do not overtighten by feel alone. Inspect the insert seat for debris or damage before seating a new tip to ensure proper alignment and runout.
