The Mitsubishi TPMH110308-MV UE6020 is a positive, 60° triangular turning insert with MV chipbreaker and UE6020 coated carbide grade — designed for medium-cutting applications in steel and stainless. Known for excellent chip control, long life, and reduced cost per part, it’s one of our top sellers at CNC Tools Depot.
Boost your machining performance with Mitsubishi’s TPMH110308-MV UE6020 — engineered for precision, reliability, and long tool life.
The TPMH110308-MV is a positive-style triangular turning insert from Mitsubishi Materials, designed for medium cutting of steels and stainless steels. Featuring the proven MV chipbreaker and advanced UE6020 coated carbide grade, it delivers superior chip control, consistent surface finish, and exceptional wear resistance — even in demanding or slightly unstable cutting conditions.
Cut faster. Last longer. Slash your cost per component with Mitsubishi’s TPMH110308-MV UE6020 — the turning insert your shop can’t afford to be without
Geometry: 60° triangular insert, positive orientation, IC = 6.35 mm, thickness = 3.18 mm, corner radius RE = 0.8 mm
Chipbreaker / Breaker: MV (medium cutting), with double breakers and round-shaped dots in the rake face for stable chip control, even under unstable cutting conditions
Grade / Coating: UE6020 (Mitsubishi’s coated carbide grade) — optimized for steel, alloy steel, mild steel, stainless steel
Cutting Applications: Best suited for medium turning, especially in steel & stainless, in both stable and moderately unstable cutting operations
Less downtime: The MV chipbreaker ensures consistent chip flow and avoids chip clogging, even in varying cut conditions.
Better surface finish: The positive geometry combined with UE6020 grade helps produce cleaner finishes with minimal burrs.
High wear resistance: UE6020’s coating and carbide core resist flank wear and crater wear when machining steels and stainless, extending tool life.
Stable performance in tricky cuts: Even under slight vibration or less-than-ideal rigidity, MV’s chip control holds.
Cost-effective: Fewer insert changes, fewer rejects, lower scrap = real bottom-line gains.
This insert is ideal for:
Automotive component turning (shafts, bushings)
Aerospace parts (where steels and stainless components are common)
Die & mold work (precision steel parts)
General engineering / maintenance operations (shafts, pins, spindles)
It excels in carbon steel, alloy steel, mild steel, and stainless steel applications — especially in medium cutting conditions.
With the MV chipbreaker and positive geometry, it handles both stable and moderately unstable cuts well. The double breakers and dot pattern assist in chip discharge.
nscribed circle (IC): 6.35 mm
Thickness: 3.18 mm
Corner radius (RE): 0.8 mm
UE6020 is a well-balanced, coated grade optimized for wear resistance in steels and stainless. It offers strong flank and crater wear resistance compared to more basic grades.
TPMH-series inserts are designed primarily for turning (with hole / positive inserts). It is not intended for milling or drilling. Use turning toolholders that accept triangular positive inserts.
