Sandvik Coromant 7357779 Replaceable Drill Tip 15mm Grade 2334

Product Description

The SANDVIK COROMANT 7357779 is a replaceable drill tip engineered for use in CoroDrill 870 modular drilling systems. It features a 15.00 mm (0.6102 inches) cutting diameter and a 142-degree drill point angle, making it well suited for stable entry and clean hole formation. The tip is manufactured from solid carbide with a fine grain microstructure and carries an AlTiCrN coating applied via PVD process. This combination delivers strong wear resistance and thermal stability under demanding cutting conditions. Licensed HVAC, plumbing, and mechanical contractors as well as machining professionals install these tips in production and maintenance drilling operations on stainless steel, superalloys, and titanium workpieces.

This replaceable drill tip is designed for solid drilling applications in industrial and manufacturing environments. Its helical flute geometry and regular spiral type promote chip evacuation during through-hole and blind-hole operations. The clamp-based insert holding method ensures repeatable seating at seat size 15. Primary workpiece materials include stainless steel, superalloys, and titanium, corresponding to ISO material groups M and S. The MM insert geometry and 870-1550-15-MM 2334 ISO designation identify the exact seat and tip configuration required when ordering or cross-referencing replacement tips for CoroDrill 870 tool bodies.

Key Features

• Solid carbide construction with fine grain microstructure for edge integrity under high cutting loads
• AlTiCrN PVD coating provides oxidation resistance and extended tool life on hard-to-machine alloys
• 142-degree point angle supports stable drill entry and reduced thrust force
• Helical, regular-spiral flute design aids chip flow during stainless steel and superalloy drilling
• Clamp-type insert holding at seat size 15 ensures consistent tip positioning and quick changeover
• Designed for CoroDrill 870 modular system, enabling tip replacement without discarding the drill body

Compatibility

This tip is compatible with CoroDrill 870 series modular drill bodies accepting seat size 15. The ISO designation 870-1550-15-MM 2334 identifies the required seat and geometry configuration for proper fitment.

Installation Notes

Replaceable drill tips of this type are installed and changed by machining technicians or tooling specialists. Before replacing the tip, ensure the machine spindle is fully stopped and the tool is secured in a fixture or tool holder per shop safety procedures. Use the appropriate clamping torx or hex key as specified by the drill body manufacturer for the seat size 15 interface. Inspect the insert seat for chips or debris before seating the new tip to ensure full contact and accurate runout.
