DCMT11T304-MV UE6020
High-Efficiency Steel Machining | UE6020 CVD Grade | MV Versatile Geometry
Engineered for High-Speed Reliability in Steel
UE6020 Grade (CVD Coating): The UE6020 is Mitsubishi’s flagship CVD-coated carbide for P-Class (Steel). It is specifically engineered to resist the extreme heat generated during high-speed continuous cutting. The multi-layered coating provides a hard outer shell that resists crater wear and a tough substrate to prevent edge breakage, ensuring stable tool life across thousands of parts.
MV Chipbreaker (Medium-V): The MV geometry is a versatile semi-finishing chipbreaker. It features a balanced rake angle that provides a sharp cutting action while maintaining enough edge strength for varied depths of cut. It is designed to provide consistent chip evacuation in carbon steels, preventing the "long chip" issues that cause downtime.
0.4mm Radius (The All-Rounder): The "04" (1/64") nose radius is the most common choice for general-purpose turning. It allows for high-quality surface finishes while maintaining enough mass to withstand the pressures of semi-finishing cuts.

Shop SDJCR 11 HoldersPro-Tip: UE6020 vs. US735
UE6020 (CVD): Optimized for steel production. It handles high-speed friction heat much better than other grades, making it the best for continuous turning.
US735 (CVD): Switch to US735 only if you are machining stainless steel or if you have heavy interruptions. US735 is tougher, but UE6020 is much faster in pure steel.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
