OYYU TGF32R/L Vertical Shallow Grooving Carbide Inserts (CW 0.5mm - 3.0mm) - OY880A Grade
⚡ Quick Buyer's Selection Guide (How to Choose Hand & Width):
- Hand Orientation: Choose TGF32R for Right-Hand toolholders (spindle forward M03); Choose TGF32L for Left-Hand toolholders.
- Narrow Circlip / O-Ring Grooving (0.5mm - 1.2mm): Select TGF32R/L050 to L120 for precision snap-ring channels.
- Medium External Grooving (1.3mm - 2.0mm): Select TGF32R/L130 to L200 (P200 2.0mm is the Industry Standard).
- Wide Shallow Profiling (2.1mm - 3.0mm): Select TGF32R/L210 to L300 for high-feed wide groove parting and shallow recessed profiles.
1. Product Overview
Which vertical clamping carbide insert delivers maximum lateral stability, zero chatter, and sub-micron width accuracy for shallow external grooving, O-ring sealing channels, and snap-ring grooves on CNC lathes?
The OYYU TGF32R/L Grooving Series (ISO/ANSI vertical insert geometry) is an industrial-grade precision cutting insert system engineered specifically for shallow grooving, profiling, and parting off. Featuring a standing 3-point vertical contact pocket design, the TGF32 system directs cutting forces directly downward into the toolholder shank, eliminating flank deflection and chatter common in conventional horizontal inserts.
Available in 52 precise specifications ranging from 0.5mm (0.0197") to 3.0mm (0.1181") width increments, every insert is precision-ground with a specialized micro-curved chipbreaker. Coated with OYYU’s flagship OY880A Nano-TiAlN PVD Coating over an ultra-fine carbide substrate, these inserts resist built-up edge (BUE) and thermal micro-cracking across ISO P (steels), ISO M (stainless steels), and ISO K (cast iron) turning operations.
2. Key Features
- Vertical Clamping System (TGF32 Standard): Vertical seating geometry resists immense lateral thrust forces during shallow grooving and profiling without tool movement.
- 52 Ultra-Precise Cutting Width Options (CW 0.5 - 3.0mm): Incremental 0.1mm width availability allows exact matching to DIN 471 / DIN 472 retaining ring and O-ring specifications.
- OY880A Nano PVD Coated Micro-Grain Substrate: Multi-layer AlTiN PVD coating provides extreme surface hardness (HV 3200) and heat resistance up to 1100°C for dry and wet turning.
- 3D Precision Molded Chipbreaker: Curls continuous stringy steel chips into tight C-shape coils to prevent chip wrapping around the tool post.
- Right-Hand (TGF32R) & Left-Hand (TGF32L) Availability: Complete symmetry matching all standard external shallow grooving shanks (KGDFR/L, STGFR/L).
