SNMN 120408 TH10 SNMN Milling Insert – Tungaloy

SNMN120408 TH10 SNMN is an indexable milling insert for Tungaloy milling systems, optimised for face, shoulder, slot, high-feed and contour milling when used with matching cutter bodies.

• Universal TH10 grade for non-ferrous materials
• Square 12 mm insert, 0.8 mm corner radius
• Uncoated cemented carbide for low cutting forces
• Matched to Tungaloy milling systems, 90° geometry

Efficient, low-force cutting with the TH10 grade

The TH10 grade is an uncoated cemented carbide formulation designed to deliver a sharp cutting edge and low cutting forces when machining non-ferrous materials. This results in cleaner surface finishes and reduced burr formation, particularly on aluminium alloys and softer non-ferrous metals. The uncoated edge is advantageous where thermal resistance of coatings is unnecessary and where minimal built-up edge is critical. In practice, operators gain predictable part quality across a range of light- to medium-duty milling tasks, with the grade emphasising process stability over extreme wear resistance.

Predictable results from precise geometry and radius

A square insert with a nominal 12 mm side and a 0.8 mm corner radius offers a clear balance between edge strength and surface finish. The 0.8 mm corner radius increases the contact area at the cutting edge, improving tool life under intermittent loading while still producing a fine surface on planar and shoulder faces. The insert’s 90° orientation supports straightforward toolpath planning for perpendicular face milling and robust shoulder operations. In practical terms, the geometry reduces vibration risk and helps maintain dimensional accuracy when the insert is correctly seated and clamped.

System compatibility and reliable clamping

The milling system is assembled from a cutter body, the indexable insert, a clamping screw and, where required, a support shim. It is essential that insert seat, geometry and clamping method are matched to the cutter family to ensure secure fixation and repeatable indexability. When integrated into a Tungaloy milling body, the insert provides consistent chip formation and stable cutting behaviour. The absence of a chipbreaker means chip control must be managed via cutting parameters and toolpath strategy, particularly for long continuous cuts or thin-walled workpieces.

Application guidance and handling recommendations

Typical uses include face milling, shoulder milling, slotting, high-feed and contour milling, depending on the chosen cutter family. The uncoated nature of the grade makes it suitable for aluminium, brass and many plastics, where sharp edges reduce cutting forces and improve finish. For steels or hardened materials, consider coated or tougher grades suited to higher thermal and abrasive loads. Handling notes: inserts should be inspected at index changes, clamping screws torqued to the manufacturer’s specification, and any insert with edge damage replaced to preserve cutter body integrity and part quality.

FAQ

What materials is this insert best suited for? This SNMN120408 TH10 indexable milling insert is intended primarily for non-ferrous materials such as aluminium and brass, and also performs well on many plastics due to its uncoated, sharp TH10 carbide edge.

Is the insert compatible with all Tungaloy cutter bodies? The insert will function correctly when the insert seat, geometry and clamping of the cutter body match the SNMN120408 specification; ensure the chosen cutter family is designed for SNMN-style inserts.

How does the 0.8 mm corner radius affect part finish and tool life? A 0.8 mm corner radius provides improved edge strength and reduced vibration, yielding better tool life under interrupted cuts while still delivering a fine surface finish on faces and shoulders.

Does this insert include a chipbreaker or through-hole? The SNMN120408 TH10 insert is supplied without a chipbreaker and without a hole, so chip control should be managed with suitable cutting parameters and toolpath strategies.

When should a coated grade be chosen instead of TH10? For higher temperatures, abrasive workpieces or hardened steels, a coated or tougher grade is recommended; TH10 is optimised for low-force cutting and excellent finishes on non-ferrous materials.
