TCMW16T304 HTI10
Mitsubishi Materials | The Professional Standard for Non-Ferrous Machining
The Mitsubishi TCMW16T304 HTI10 is a high-hardness uncoated carbide insert specifically engineered for aluminum turning, copper, and other non-ferrous alloys. The HTI10 grade utilizes a micro-grain substrate that allows for an incredibly sharp cutting edge, effectively preventing material adhesion. As a premium indexable turning insert with a flat-top (W) geometry, it is the first choice for precision machining where a mirror-like surface finish is required.

HTI10 Grade Technology
The HTI10 grade is an uncoated tungsten carbide with a micro-grain structure. By omitting the coating, Mitsubishi ensures the sharpest possible cutting edge. This prevents built-up edge (BUE), a common failure in non-ferrous turning. It offers high hardness and excellent wear resistance for abrasive aluminum alloys (high silicon content).
TCMW Flat Top Geometry
The "W" designation indicates a flat-top insert without a molded chipbreaker. This design is optimized for stable turning of materials that produce fragmented chips or where very light depths of cut are used. It ensures maximum edge strength and superior surface integrity on the workpiece.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Aluminum Alloys | 200 - 800 m/min | 0.05 - 0.25 mm/rev | 0.1 - 2.5 mm |
| Copper / Brass | 150 - 400 m/min | 0.05 - 0.20 mm/rev | 0.1 - 2.0 mm |
