· Product Overview
Introducing the YITECH Precision Stainless Steel Tool Adapter Hub — a CNC-machined functional component engineered for repeatable tool mounting, high-stiffness coupling, and corrosion-resistant operation in demanding industrial, medical, and aerospace environments.
This adapter delivers:
- Solid 304 or 316L stainless steel construction — non-magnetic (316L), highly corrosion-resistant (salt spray ≥ 96 hrs), and biocompatible
- Integrated mechanical locking system:
- Threaded shank (M6/M8 standard) for secure mounting
- Radial through-hole (Ø2.5 mm) for M3 set screw (prevents rotation under torque)
- Flanged collar with 3 symmetric radial slots — enables wrench tightening and visual indexing (0°/120°/240°)
- Precision-machined geometry:
- Central bore: Ø6.0 mm H7 (±0.018 mm), depth 12 mm
- Concentricity: ≤ 0.005 mm TIR (bore to shank axis)
- Surface finish: Ra 0.2 μm (mirror-polished bore), Ra 0.4 μm (external)
- No coatings, no plating — passivated per ASTM A967 (nitric acid, Method 1) for optimal corrosion resistance and cleanability
Unlike aluminum or plated steel adapters (prone to galling, corrosion, or wear), our stainless hubs offer long-term reliability, zero degradation in humid/chemical environments, and FDA-compliant surface integrity — even after 10,000+ tool insertions.
Ideal for engineers building medical instrument changers, lab automation tooling, underwater ROV interfaces, or high-end CNC accessory systems where sterility, durability, and precision are non-negotiable.
