RDMW(R5R6) Carbide Milling Inserts: Performance, Applications, and Advantages
Introduction
Milling inserts are the core components of modern machining, directly influencing cutting efficiency, surface finish, and tool life. Among them, RDMW(R5R6) carbide inserts (including RDMW10T3MO, RDMW10T3MOA, RDMW1204MO, RDMW1204MA, RPMW08T2MOA, RPMW1204MO, RPMW1204MOA, RPMW1003MO, RPMW10T3MO, RDET10T3MOT, RDET1204MOT, RDMW1204MOTA-PM, RDMW1204MOT-PM, RDMW1605MOTA-PM, and RDMW1605MOT-PM) are widely recognized for their high performance and versatility.
Manufactured from premium carbide material, these inserts are specially engineered for high-speed milling, roughing, semi-finishing, and finishing applications across industries such as aerospace, automotive, mold-making, and general machining.
This article provides a comprehensive overview of RDMW(R5R6) carbide milling inserts, covering their advantages, performance parameters, applications, key features, precautions, and innovative technologies.
1. Advantages of Carbide Inserts in Milling
Carbide milling inserts, compared with high-speed steel (HSS) or ceramic tools, offer unmatched advantages:
Superior Hardness & Wear Resistance
Tungsten carbide, with hardness levels around 92 HRA, ensures long service life.
Excellent wear resistance even under high-speed and heavy-load cutting.
Thermal Stability
Can withstand cutting temperatures above 800°C.
Minimizes tool deformation and maintains sharp cutting edges.
High Efficiency
Supports high-speed machining (HSM), increasing productivity.
Allows deeper cutting depths and higher feed rates.
Versatility
Suitable for a wide range of materials: steel, stainless steel, cast iron, titanium alloys, and non-ferrous metals.
Cost-Effectiveness
Indexable inserts allow multiple cutting edges per insert, reducing tool replacement cost.

2. Understanding RDMW(R5R6) Parameters
The nomenclature (letters and numbers) of carbide inserts provides critical information for engineers:
R = Round insert shape (offers high strength and durability).
D / P = Insert style or clearance angle.
M / T = Tolerance class and chipbreaker design.
W = Double-sided insert, more cutting edges for economy.
Numbers (10T3, 1204, 1605, etc.) = Insert size: diameter, thickness, corner radius.
Example: RDMW1204 → Diameter 12 mm, thickness 4 mm.
MO, MA, PM = Chipbreaker types for different cutting conditions:
MO: General-purpose medium cutting.
MA: Finishing application with excellent surface finish.
PM: Optimized for steel with balanced performance.
These parameters allow precise selection based on workpiece material, cutting depth, and feed rate.

End mill for machining aluminum materials
Many customers have told us that ordinary end mills frequently stick when machining aluminum, and the accumulation of chips affects the accuracy, so they always change the tools. LIZHOU editor suggests that coated end mills are not recommended for aluminum materials, because some coatings contain aluminum elements. Therefore, it is better to choose uncoated end mills when selecting end mills for machining aluminum materials.
