Sandvik Coromant 7357937 Replaceable Drill Tip 0.75 in

Product Description

The SANDVIK COROMANT 7357937 is a replaceable drill tip designed for use with the CoroDrill 870 modular drilling system. This solid carbide insert features an AlTiCrN coating applied via PVD process, a 142-degree point angle, and MM insert geometry with a seat size of 19. It is engineered for indexable drilling operations where the tip can be swapped without removing the drill body from the machine, reducing downtime in production environments. Licensed machinists and tooling technicians install this component in CNC turning centers and machining centers.

This drill tip is rated for primary use in stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material codes M and S. The fine grain carbide substrate and AlTiCrN coating provide thermal and wear resistance suited to these demanding materials. It fits seat size 19 CoroDrill 870 bodies and is appropriate for solid drilling applications in both job shop and high-volume production settings. The helical flute design and regular spiral promote chip evacuation in difficult-to-machine alloys.

Key Features

• Solid carbide construction with fine grain substrate for edge toughness in hard materials
• AlTiCrN coating via PVD process for thermal resistance and extended tool life in stainless steel and titanium
• 142-degree point angle optimized for reduced thrust and entry stability
• MM insert geometry with seat size 19 for secure clamped retention in CoroDrill 870 bodies
• 2-flute helical design promotes chip evacuation during solid drilling
• Indexable tip replacement without disturbing drill body setup

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 modular drill bodies with insert seat size 19, ISO number 870-1905-19-MM 2334. Compatible with workpiece materials classified under ISO codes M (stainless steel) and S (superalloys and titanium).

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The drill body must be fully de-energized and the machine spindle locked before removing or seating the tip. Use the manufacturer-specified torx or clamp screw and follow the tool body documentation for proper seating torque — do not apply values not confirmed in the official product documentation. Inspect the insert seat for chips or debris before mounting to ensure correct tip engagement and runout.
