TCMW16T308 HTI10
Mitsubishi Materials | The Standard for Aluminum & Non-Ferrous Turning
The Mitsubishi TCMW16T308 HTI10 is an uncoated carbide insert specifically engineered for high-precision machining of non-ferrous materials. Utilizing the legendary HTI10 micro-grain grade, this insert provides a superior balance of hardness and toughness. As a critical long-tail precision tool, its 0.8mm nose radius provides reinforced edge strength, making it the industry benchmark for stable, high-speed aluminum turning and copper machining.

HTI10 Grade Technology
The HTI10 grade is an uncoated carbide consisting of a high-hardness micro-grain substrate. Without a coating, the edge remains razor-sharp, which is vital for preventing built-up edge (BUE) in "sticky" materials. This makes it ideal for non-ferrous turning and finishing cast iron.
TCMW Flat-Top Geometry
The "W" designation refers to a flat-top insert (no chipbreaker). This geometry is optimized for precision machining of materials that produce fragmented chips or in applications where the tool must provide maximum stable turning stability and clean shearing action.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
