Sandvik Coromant 7358082 Replaceable Drill Tip 22.23mm

Product Description

The SANDVIK COROMANT 7358082 is a replaceable drill tip designed for use with CoroDrill 870 modular drilling systems. It features a 22.23 mm (0.8752 inch) cutting diameter and a 142-degree included point angle, making it well suited for controlled entry and exit in demanding materials. The tip is manufactured from solid carbide with a fine grain substrate and carries an AlTiCrN coating applied via PVD process, providing heat resistance and edge stability. Insert geometry is MM with a seat size of 22. Licensed machinists and CNC operators working in production or job-shop environments install and change these tips at the machine.

This drill tip is intended for solid drilling applications where the primary workpiece materials are stainless steel, superalloys, and titanium — material groups M and S in ISO classification. These are among the most demanding materials in metal cutting, requiring a tough, heat-resistant carbide grade. The CoroDrill 870 platform is a common choice in aerospace, medical device, and energy sector machining where hole quality and tool life in difficult alloys are priorities. The helical flute design with regular spiral promotes chip evacuation during drilling cycles.

Key Features

• Solid carbide construction with fine grain substrate for edge toughness in hard and abrasive materials
• AlTiCrN PVD coating provides thermal and oxidation resistance at elevated cutting temperatures
• 142-degree point angle optimized for entry and exit control in stainless steel, superalloys, and titanium
• MM insert geometry with seat size 22 for direct compatibility with CoroDrill 870 holders
• Helical flute with regular spiral promotes reliable chip flow during through-hole and blind-hole drilling
• Clamp-held insert retention for repeatable tip positioning and quick changeover at the spindle

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 series modular drill bodies that accept seat size 22 with MM insert geometry. ISO number 870-2223-22-MM 2334 identifies the tip within the CoroDrill 870 system.

Installation Notes

Installation and tip changes are performed by machinists or tooling technicians following the machine tool manufacturer and SANDVIK COROMANT CoroDrill 870 tooling assembly procedures. Ensure the spindle is stopped and the machine is in a safe, locked-out state before removing or installing any drill tip. Use the correct torx or clamping key specified for the CoroDrill 870 holder to achieve proper seating — do not overtighten or substitute hardware. Inspect the insert seat for chips or debris before seating the new tip to ensure accurate positioning and full clamping contact.
