DNMG 150412 T5105 DNMG Turning Insert — CVD-coated carbide, 55° — Tungaloy

DNMG150412 T5105 is an ISO-standard rhombic insert designed for high-speed external and internal turning, optimised for stable machining of cast iron under controlled conditions

• CVD-coated carbide for high wear resistance
• Rhombic 55° geometry for versatile turning
• Double-sided chipbreaker for extended tool life
• Cylindrical hole for secure clamping

Reliable performance for high-speed turning of cast iron

The T5105 grade is a CVD-coated carbide developed for wear resistance in high-speed applications. In practice, the coating reduces flank and crater wear so that production runs remain consistent and predictable; this means fewer unexpected tool changes and more stable cycle times. The insert’s substrate delivers toughness, while the coating maintains edge integrity during continuous cutting, which is particularly beneficial when machining cast materials under steady setups.

ISO compatibility and secure mounting reduce setup time

Manufactured to ISO dimensions, the insert ensures compatibility with standard holders when form, relief angle, tolerance class, attachment method, size and thickness match the toolholder. The cylindrical hole facilitates positive clamping and repeatable seating, allowing clamping forces to be transmitted securely. This compatibility avoids costly guessing during tool changeovers and supports a system approach comprising an insert, matching outer holder or boring bar, seating pad and fasteners.

Geometry and chip control for consistent finishes

The rhombic 55° geometry combines accessibility for external and internal turning with favourable cutting-edge engagement. The integrated double-sided chipbreaker is engineered to create short, controllable chips, improving surface finish and reducing the risk of chip entanglement in enclosed operations. For applications that demand consistent part quality, this geometry supports reliable surface integrity with minimal secondary operations.

Practical system considerations and selection guidance

A productive cutting system comprises the insert, a compatible outer holder or boring bar, an appropriate seating pad or clamp kit, and spare screws. The 4.76 mm thickness and 15 mm size contribute to stable clamping in most standard ISO toolholders, while the 1.2 mm corner radius balances edge strength with achievable surface finish. Select the chipbreaker and grade to match the workpiece, machining mode and rigidity of the setup to obtain the best life and productivity.
