Forged from high-tensile alloy steel and oil-quenched for superior HRC hardness, this 25mm shank provides excellent harmonic vibration damping. The 93° approach angle (SVJBL geometry) is the standard for general-purpose internal boring and profiling, offering a balanced trade-off between radial and axial forces. Engineered for VBMT 1604 indexable inserts, this tool ensures consistent surface finish and dimensional repeatability in production environments.\u003c\/p\u003e\n\u003ch2 style=\"color: #47479f; border-bottom: 2px solid #47479F; padding-bottom: 8px; font-size: 19px; margin-top: 30px;\"\u003e2.
