Sandvik Coromant 7357906 Replaceable Drill Tip 0.7205 in

Product Description

The SANDVIK COROMANT 7357906 is a replaceable drill tip designed for use with the CoroDrill 870 modular drilling system. It features a 0.7205-inch (18.00 mm) cutting diameter and a 142-degree drill point angle ground from solid carbide fine-grain substrate. The tip carries a TiAlN coating applied via PVD process, which supports heat resistance and tool life across a range of workpiece materials. Insert seat size 18 and a clamp-style holding method secure the tip in the matching CoroDrill 870 holder. Licensed HVAC, plumbing, and metalworking tradespeople working with precision hole tolerances rely on consistent tip geometry across production runs.

This drill tip is suited for solid drilling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. ISO material codes P, M, K, N, and S are all listed as primary workpiece material categories. The PM insert geometry and regular helical spiral flute design support chip evacuation in through-hole and blind-hole applications. The tip does not include through-coolant capability, so external or flood coolant should be considered for heat-sensitive workpiece materials or deeper hole applications. Functional length is 0.3358 inches with an overall projection of 0.4449 inches.

Key Features

• Solid carbide fine-grain substrate for rigidity and edge stability
• TiAlN PVD coating supports thermal resistance and extended tool life
• 142-degree point angle with PM geometry for controlled cutting action
• Compatible with CoroDrill 870 insert seat size 18 holders
• Two helical flutes with regular spiral for consistent chip flow
• Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 series drill bodies accepting insert seat size 18. ISO number 870-1830-18-PM 4334 identifies the correct holder pairing. This tip is not compatible with through-coolant configurations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable modular drilling systems. Power down and de-energize the machine spindle completely before removing or seating the drill tip. Use the correct torque wrench and clamp screw specified by SANDVIK COROMANT for seat size 18 to avoid tip movement or seating damage. Inspect the insert pocket for chips or debris before seating the new tip, as contamination affects runout and hole quality.
