S: Square shape offering four functional cutting edges.
C: 7-degree positive side clearance angle to reduce tool friction against the workpiece.
G: Precision tolerance class ensuring high dimensional repeatability across insert replacements.
X: Specialized insert geometry typically unique to the manufacturer's pocket seating design, complete with a countersunk screw hole.
09: Nominal cutting edge length / insert seat size code of 9.52 mm (0.375 inches).
04: Standard insert thickness of 4.76 mm.
08: Corner nose radius of 0.8 mm to optimize structural strength and hole surface finish.
DP3000: Seco Tools Duratomic® coated grade. It utilizes a heavy-duty CVD TiCN+Al2O3 multi-layer coating engineered for structural steel, stainless steel, and iron milling/drilling with maximum application security.
