SNMA 120404 T5105 – Tungaloy turning insert, CVD-coated cemented carbide, 90° square

SNMA120404 T5105 is an ISO-format turning insert designed for high-speed machining of cast iron under stable cutting conditions

• CVD-coated cemented carbide for high speeds
• Square ISO SNMA form, 90° included angle
• 0.4 mm corner radius for fine finishing
• Cylindrical hole for secure attachment

Consistent edge performance for productive turning

The CVD-coated cemented carbide of grade T5105 is engineered to maintain a stable cutting edge during continuous, high-speed turning of cast iron. The coating improves wear resistance and reduces adherence of abrasive particles, which translates into longer effective tool life and fewer interruptions in production. With a controlled chip flow in stable setups, the insert supports predictable cycle times and consistent surface finish — a clear efficiency gain for serial machining where repeatability matters.

Designed to fit standard ISO tooling systems reliably

Compatibility with tool holders is governed by the insert form, 0° relief, tolerance class, fastening method and the plate’s dimensions. The SNMA geometry is an ISO standardised square insert with a 90° included angle, allowing it to be used in a wide range of external and internal turning holders. The central cylindrical hole ensures positive clamping; matching the holder by shape and thickness (plate thickness 4.76 mm) secures correct seat and repeatable positioning for stable machining operations.

Small radius, precise finishing and versatile application

The 0.4 mm corner radius provides a balance between light finishing and adequate strength for interrupted cuts when conditions are steady. In combination with the square geometry, this radius performs well for profile work and general turning where a finer edge is required. Opting for a grade without an integrated chipbreaker means chip management must be matched to the machine setup and workpiece; the result is a versatile insert that can be tuned for finishing or general-purpose turning by selecting appropriate cutting parameters and holder geometry.

Practical selection guidance and process benefits

Choosing the right insert grade and matching holder is essential: select the T5105 grade for high-speed cast-iron operations under stable conditions; consider a different grade or a variant with a chipformer when facing severe interruptions or poor rigidity. The square SNMA form offers balanced strength and multiple indexable edges, which can reduce tooling cost per component in lot production. For customers seeking predictable tool life and a controlled surface outcome, this configuration supports efficient machining with clear process advantages.

FAQ

What applications suit this insert best? This SNMA120404 T5105 turning insert (Tungaloy, SKU 6853004-Tungaloy) is intended mainly for high-speed machining of cast iron in stable setups, including external and internal turning.

Is the insert compatible with common ISO holders? Yes; the SNMA geometry is ISO-standard and will fit holders that accept SNMA plates when the holder matches the plate thickness, form and clamping method.

How does the T5105 grade affect tool life? The CVD-coated T5105 grade is designed for wear resistance at high cutting speeds on cast iron; this typically extends edge life under steady conditions compared with uncoated grades.

Does this insert include a chipbreaker? No, the insert is supplied without an integrated chipbreaker, so chip control depends on holder geometry and cutting parameters.

What finishing capability does the 0.4 mm radius offer? The 0.4 mm corner radius supports fine finishing and profile work while retaining enough edge strength for light interruptions in stable machining environments.
