DNMG150612 T9215 — Tungaloy ISO turning insert, CVD-coated carbide, 55°

DNMG150612 T9215 is an ISO-compliant indexable turning insert designed for productive external and internal turning of medium steels.

• CVD-coated cemented carbide for medium steel
• DNMG 55° rhombic insert, ISO 150612
• 1.2 mm corner radius for edge strength
• Double-sided chipbreaker for reliable chips
• Cylindrical hole for secure clamping

Productive CVD-coated grade for medium-steel turning

The T9215 grade is a CVD-coated cemented carbide developed for the mid-range machining of steel where a balance of wear resistance and fracture toughness is required. The coating provides a hard, heat-resistant surface that reduces flank wear and maintains edge integrity under continuous to slightly interrupted cuts, resulting in longer tool life and more consistent component tolerances. This makes the insert particularly suitable for series production where repeatable performance matters.

Geometry and clamping that ensure compatibility and stability

The rhombic DNMG geometry with a 55° approach angle and a 0° relief ensures versatile turning capability and predictable cutting forces. The insert features a cylindrical hole for positive, repeatable seating in ISO-standard holders; compatibility with a specific holder is governed by form, clearance angle, tolerance class, clamping method, size and thickness. The 6.35 mm thickness and standard 15 mm inscribed size give a robust platform that resists deflection in both external and internal applications.

Chip control and process security for efficient machining

A double-sided chipbreaker integrated into the cutting face promotes controlled chip formation and evacuation, lowering the risk of built-up edge and improving surface finish. For medium steels, the combination of stable chip formation and the T9215 grade’s resistance to flank wear supports higher cutting data and productivity. Where slight interruptions occur, the grade’s fracture resistance helps maintain production continuity and reduces unexpected tool changeovers.

Practical handling and predictable edge life

A 1.2 mm corner radius balances edge strength with finish requirements: it reinforces the cutting edge for tougher feeds while still allowing acceptable surface quality on finished parts. The insert’s double-sided nature and standardised geometry simplify inventory management and reduce set-up time during index changes. Compatibility guidance and matching clamping sets are recommended to achieve optimal repeatability and tool life in specific machine-tool-holder combinations.

FAQ

What materials is this insert best suited for? The Tungaloy DNMG150612 T9215 insert is optimised for machining medium steels, combining wear resistance with toughness for reliable productivity.

How does the T9215 coating improve performance? The CVD-coated cemented carbide surface of the T9215 grade increases thermal and abrasive resistance, which reduces flank wear and prolongs usable edge life under production cutting conditions.

Will this insert fit my existing ISO holder? Compatibility is determined by insert form, relief angle, tolerance class, clamping method, size and thickness; the DNMG150612 format is ISO-standard and will fit ISO DNMG holders when these parameters match.

What benefits does the double-sided chipbreaker provide? The double-sided chipbreaker promotes controlled chip formation and evacuation, improving surface finish and reducing the chance of chip-related interruptions during turning operations.

Which SKU should be ordered for this item? Order using manufacturer SKU TUN6772271 or article number 6772271 to ensure the correct Tungaloy DNMG150612 T9215 turning insert is supplied.
