FAQ

What thread sizes are compatible with the AA181‑420?

The AA181‑420 is specifically sized for a 1/4‑20 thread, making it compatible with AVK’s A‑K, A‑L, A‑P, and A‑O series threading holders. This size is commonly used in a wide range of industrial applications, from aerospace component machining to automotive part production, ensuring a versatile fit across many machine platforms.

How does the black coating benefit the tool?

The black powder‑coat finish serves multiple purposes. It provides a barrier against moisture, chemicals, and abrasive particles that can cause corrosion or surface degradation. Additionally, the dark color helps conceal oil, grime, and minor wear, keeping the tool looking professional and reducing the frequency of cleaning cycles in busy shop floors.

Can the tool be used with other manufacturers’ equipment?

While the AA181‑420 is optimized for AVK’s own threading holder series, its standard 1/4‑20 thread size aligns with many industry‑wide specifications. Users can often employ the tool with compatible third‑party equipment that adheres to the same thread dimensions, though it is recommended to verify clearance and fit before full‑scale implementation.

What warranty and support does AVK provide?

AVK offers a limited one‑year warranty covering material and workmanship defects for the AA181‑420. Customers have access to a dedicated technical support line, online resources, and downloadable installation manuals. Should any issues arise, AVK’s service team will assist with troubleshooting, replacement parts, or guidance to ensure uninterrupted operation.

Is the tool suitable for high‑speed machining environments?

Yes. The hardened‑steel body maintains dimensional stability even under high‑speed rotational forces, and the secure 1/4‑20 thread connection prevents slippage during rapid machining cycles. The tool’s design minimizes vibration transmission, helping to preserve surface finish quality and extend the lifespan of both the tool and the machine it is mounted on.
