Sandvik Coromant 7358037 Replaceable Drill Tip 21mm

Product Description

The SANDVIK COROMANT 7358037 is a replaceable drill tip designed for use with CoroDrill 870 modular drilling systems. It features a 21.00 mm (0.8346 inch) cutting diameter, a 142-degree drill point angle, and a solid carbide construction with a fine grain material grade. The AlTiCrN coating is applied via PVD process, providing thermal resistance and wear protection during demanding drilling operations. This tip installs via clamp-style insert holding into a size 21 seat and is intended for professional machinists and tooling technicians working with high-performance drill bodies.

This drill tip is engineered primarily for drilling stainless steel, superalloys, and titanium, making it suited to aerospace, medical, and heavy industrial machining environments. The MM insert geometry and regular helical spiral support chip evacuation in these difficult-to-machine materials. With a flute length of 10.00 mm and an overall projection of 0.5197 inches, this tip fits solid drilling applications where precise, repeatable hole geometry is required. It is sold individually and is intended as a direct replacement tip within a compatible CoroDrill 870 drill body system.

Key Features

• 21.00 mm cutting diameter with 142-degree standard point angle for accurate entry in tough alloys
• Solid carbide fine grain construction for rigidity and edge retention
• AlTiCrN PVD coating for high-temperature wear resistance in stainless steel and superalloy applications
• MM insert geometry with regular helical flutes for effective chip evacuation
• Clamp-style holding method for secure, repeatable tip seating in CoroDrill 870 bodies
• 2-flute helical design optimized for solid drilling operations

Compatibility

Designed for use with CoroDrill 870 series modular drill bodies accepting an insert seat size 21 and MM insert geometry. Verify seat size and geometry code on the drill body before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and locked out before tip replacement. Ensure the seat and clamping surfaces are clean and free of chips or debris prior to seating the tip. Use the appropriate torque wrench and clamp screw specified by the drill body manufacturer — do not overtighten. Inspect the seat for wear or damage each time the tip is replaced to maintain positional accuracy.
