Sandvik Coromant 7549912 Indexable Drill Insert Grade 2044

Product Description

The SANDVIK COROMANT 7549912 is a solid carbide indexable drill insert engineered for precision drilling in metal-cutting applications. Carrying insert style DS20 with chipbreaker H5W and manufacturer grade 2044, this insert features a TiCN plus Al2O3 coating applied via PVD process, delivering improved wear resistance and thermal stability at the cutting edge. The corner radius measures 0.5 mm, and the insert is ground to an irregular shape geometry sized at insert size 0205. Machinists and CNC operators working with indexable drill toolholders install this insert as a replaceable cutting element, extending tool life between full toolholder replacements.

This insert is suited for right-hand cutting operations in drilling applications where a solid carbide substrate and multi-layer PVD coating are specified. The DS20 insert style is used in compatible Sandvik Coromant indexable drill bodies designed for the DS20 insert seat geometry. Typical use cases include production drilling in steel, stainless steel, and cast materials in shop-floor and production machining environments where consistent hole quality and insert change efficiency are priorities.

Key Features

• Solid carbide substrate for rigidity and wear resistance in demanding drill applications
• TiCN plus Al2O3 multi-layer PVD coating for elevated hardness and oxidation resistance
• Grade 2044 designation for application-specific cutting performance
• H5W chipbreaker geometry optimized for chip control during drilling
• 0.5 mm corner radius for controlled edge geometry at the cutting tip
• Right-hand cutting direction for standard CNC and manual drilling setups

Compatibility

Designed for use in indexable drill toolholders that accept the DS20 insert style with an 0205 insert size seat. Confirm toolholder seat geometry and insert style designation before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing or indexing any insert. Use the manufacturer-recommended torque wrench and clamping screw for the specific toolholder to secure the insert — do not over-tighten by hand or with non-specified tools. Inspect the insert seat for chips or debris before seating the new insert to ensure proper contact and runout.
