RDMW Indexable Carbide Insert

  About the product

The RDMW milling carbide insert is designed for multi-material machining, featuring a 15° side clearance angle and is compatible with Walter®, Dijet® and other industry supplier milling cutters. It boasts a reinforced cutting edge for increased edge security and is coated with PVD TiAlN+ for excellent heat and oxidation resistance across a wide range of ISO P, M, K, and S materials. This insert is precision pressed and is an excellent choice for roughing operations, especially in steel and cast iron. It offers superior performance and value, making it a universal, first-choice grade for a variety of workpiece materials and mixed production.

Material & Construction 

Key Features

• Precision Pressed: CNC turning cutting tools Tight dimensional tolerances (±0.01mm) ensure consistent performance across batches, minimizing setup time in automated machining.

• Rugged Roughing Design: Reinforced cutting edges and a thick core structure resist chipping under high feed rates (0.2–0.5 mm/rev) and deep cuts (3–8 mm), enabling rapid material removal.

• Broad Material Compatibility: Excel in machining steel (carbon, alloy), stainless steel (304, 316), and cast iron (gray, ductile), addressing challenges like BUE and abrasive wear.

• Enhanced Edge Security: Honed or T-land edge preparation reduces micro-fractures, extending tool life by 25–30% compared to standard inserts.

• Customizable Solutions: Available in diverse geometries (round, square), chipbreakers, and grades to tailor performance to specific roughing or semi-finishing needs.

Applications

• Automotive: Roughing engine blocks, crankshafts, and gear blanks from cast iron and alloy steel.

• Heavy Machinery: Machining large structural components (hydraulic cylinders, axle housings) from carbon steel.

• Aerospace & Energy: Roughing stainless steel turbine parts and heat-resistant alloy components requiring high wear resistance.

Lifespan

• Each cutting edge delivers 60–120 minutes of continuous use.

• Total lifespan across all usable edges ranges from 240–480 minutes, reducing tool change frequency. The wear-resistant coating and reinforced edges ensure consistent performance throughout.

Quality Assurance

Manufactured under strict quality control, including dimensional inspection, hardness testing (91–93 HRA), and coating adhesion checks. Each batch is validated for performance consistency, ensuring reliability in critical machining applications.

RDMW Carbide Inserts: Performance Parameters

Material & Coating Specifications

• Base Material: High-grade micrograin carbide with a grain size of 0.8–1.2μm, bonded with 8–10% cobalt.

• Hardness: 91–93 HRA (Rockwell A Scale), ensuring a balance of wear resistance and toughness.

• Coating Options:

• CVD Coatings (e.g., TiCN/Al₂O₃/TiN): Thickness of 5–8μm, providing oxidation resistance up to 1,000°C and enhanced wear resistance.

• PVD Coatings (e.g., TiAlN): Thickness of 3–5μm, reducing friction coefficient to ≤0.4 and preventing built-up edge (BUE) in stainless steel machining.

• 
  

Dimensional & Geometric Parameters

• Tolerances: Precision-pressed with tight dimensional accuracy of ±0.01mm for consistent fit in toolholders.

• Cutting Edge Design: Reinforced with honed or T-land edge preparation (0.02–0.05mm radius) to minimize micro-fractures.

• Core Thickness: Optimized for roughing, with a robust structure to withstand high cutting forces.

Machining Performance Metrics

• Cutting Speed Range:

• Steel (carbon/alloy): 150–250 m/min.

• Stainless Steel (304/316): 120–200 m/min.

• Cast Iron (gray/ductile): 100–180 m/min.

• Feed Rate: 0.2–0.5 mm/rev, suitable for heavy material removal.

• Depth of Cut: 3–8 mm, ideal for aggressive roughing operations.

• Surface Finish Capability: Achieves Ra ≤ 3.2μm in roughing; compatible with semi-finishing transitions with adjusted parameters.

• 
  

Durability & Lifespan

• Per Edge Lifespan: 60–120 minutes of continuous machining under optimal conditions (varies by material).

• Total Lifespan: 240–480 minutes across all usable edges, extending tool life by 25–30% compared to standard inserts due to reinforced edges and coatings.

• Wear Resistance: Maintains cutting efficiency even after prolonged exposure to abrasive materials like cast iron.

Compatibility & Operational Limits

• Toolholder Compatibility: Works with standard indexable toolholders for milling (face/shoulder) and turning applications.

• Maximum Spindle Torque Requirement: ≥50 Nm for stable performance in heavy roughing.

• Coolant Compatibility: Compatible with water-soluble and oil-based coolants to reduce heat buildup.
