HUAREAL WCMX040208-DX HR5130 80° Trigon Carbide Insert with 6.35mm IC for U-Drilling in Steel and Cast Iron

HUAREAL WCMX040208-DX HR5130 80° Trigon U-Drill Insert for Steel Drilling

The HUAREAL WCMX040208-DX HR5130 is a 80° trigon (W-type) solid carbide insert for U-drilling (indexable drill). Designed for semi-finish to medium drilling in steels, stainless steels, and cast irons, it features a DX high-efficiency chipbreaker and HR5130 PVD coated grade, delivering stable cutting, good chip evacuation, and long tool life in general-purpose hole making. Ideal for CNC drilling machines and machining centers, it covers 21–25 mm diameter holes with consistent performance.

• 80° Trigon (W-type) Geometry: Positive rake, sharp edge, reduces cutting forces and improves centering in U-drills.
• DX Chipbreaker (Drilling): Specialized groove for drilling; ensures smooth chip flow in medium depths, prevents chip clogging.
• HR5130 Grade: PVD (Ti,Al)N coating; good wear/oxidation resistance, stable at high speeds for P/M/K materials.
• 0.8mm Corner Radius (R0.8): Balances edge strength and surface finish; reduces chipping in interrupted cuts.
• Compact & Rigid: 6.35mm IC, 2.38mm thickness; fits small-to-medium U-drill bodies with high rigidity.
• Universal Application: Suitable for wet drilling with emulsion coolant; reliable in mixed batches.

• Carbon steels (1045, S355, Q235)
• Alloy steels (4140, 42CrMo4, HRC <40)
• Stainless steels (304, 316, 420)
• Gray & ductile cast irons
• Pre-hardened steels (HRC ≤40)

• U-drill / indexable insert drilling (φ21–25mm)
• Semi-finish & medium hole drilling
• CNC machining centers & drill presses
• Automotive, hydraulic, general engineering parts
• Through holes & shallow blind holes
• Light interrupted drilling (castings, forgings)

As a cost-effective , HR5130 with DX breaker delivers stable drilling performance across steel, stainless, and cast iron. The PVD coating resists high-temperature wear, while the trigon geometry ensures low vibration and good centering. It reduces downtime in hole making and offers excellent price-to-performance ratio for mass production.
