SUMITOMO WDXT042004G ACP300 PVD Coated Carbide Insert for 2D Coolant Small-Hole Drilling in CNC Metal Cutting

The SUMITOMO WDXT042004G ACP300 is a small parallelogram-shaped indexable carbide drill insert from SUMITOMO (Japan), designed for 2D internal coolant-fed drilling and general-purpose drilling/light roughing of carbon steel, alloy steel, and stainless steel. It features the G chipbreaker and ACP300 PVD-coated grade, delivering sharp cutting edges, balanced rigidity, and reliable chip evacuation in small-hole drilling.

• Insert Geometry: WDXT = Parallelogram, 2D coolant-through drill insert
• Dimensions: 0420 (Width 4.2 mm, Thickness 2.0 mm), 04 (corner radius 0.4 mm)
• Chipbreaker: G – general-purpose, optimized for light roughing and small-hole drilling
• Grade: ACP300 – PVD TiAlN/AlCrN coating, high hardness, oxidation resistance for steel (P/M)
• Workpiece: Carbon steel, alloy steel, stainless steel, cast iron
• Application: CNC small-hole drilling, hole making, light facing on Sumitomo WDX-type drill holders

• Carbon Steel (P): 1045, A36 – primary
• Alloy Steel (P): 4140, 42CrMo, SCM440 – light drilling
• Stainless Steel (M): 304, 316 – small-hole drilling
• Cast Iron (K): HT200–HT300 – general-purpose drilling

• ACP300 Grade: Balanced toughness and wear resistance, anti-built-up edge, long tool life in steel
• G Chipbreaker: Compact design for small holes, reduces cutting force, ensures stable chip flow
• 2D Coolant Design: Internal coolant supply for efficient heat dissipation in deep small holes
