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)
