Kyocera VNBR0411-003 KW10 VNB Type Small Bore Internal Boring Insert, Preset Center Height No Repeated Alignment, Micro Hole Precision Finish Boring Carbide Insert for CNC Lathe
This Kyocera VNBR0411-003 KW10 belongs to the VNB series small bore internal boring inserts, with minimum machining diameter of 4mm and 0.03mm nose radius. Factory-preset center height eliminates repeated tool alignment on machine, greatly reducing setup time and ensuring consistent positioning accuracy.
Made of KW10 grade uncoated micro-grain carbide, the insert delivers excellent hardness and thermal conductivity. It maintains sharp cutting edge during precision finish boring, achieving fine surface finish and stable dimensional tolerance on non-ferrous metals, cast iron and stainless steel tiny holes.
Designed for micro internal boring and fine finishing operations, it is compatible with matching VNB boring tool holders. Widely applied in Swiss-type lathes for precision parts manufacturing in medical, electronics and hydraulic industries, ideal for high-precision small bore machining.
