iCarbide R8 ER20 7/16 Collet Chuck Set + 3pcs 3/4 ER20 TTS Holders

Description

Product Overview

The iCarbide R8 ER20 7/16 collet chuck set is engineered for precision machining on a wide range of lathe platforms. Constructed from hardened steel, the chuck delivers exceptional rigidity while maintaining a lightweight profile that eases manual handling. The included collet nut offers a tight tolerance of 0.01 mm TIR, guaranteeing repeatable accuracy for delicate operations such as fine threading, small‑diameter drilling, and intricate turning work. Each component is finished with a corrosion‑resistant coating, extending service life even in demanding workshop environments.

Accompanying the primary chuck is a compact, impact‑resistant storage case that safeguards the chuck, collet nut, and three 3/4 ER20 TTS tool holders during transport and storage. The case’s interior foam inserts are precisely cut to hold each piece securely, preventing movement that could cause wear or damage. The three TTS (Tool Transfer System) holders are designed for rapid tool changes, allowing users to switch between cutting tools without the need for additional adapters, thereby reducing downtime and increasing productivity.

Technical specifications include a cutting diameter of 0.44 inches, a flange size of 1.5 inches, and a power source classification of hand‑powered operation, making the set compatible with both electric and manual lathe configurations. The product’s overall weight of 2.05 pounds and compact dimensions (6.3 × 2.72 × 2.64 in) ensure it can be easily integrated into existing toolboxes or bench setups.

Usage

This chuck set excels in a variety of workshop scenarios, from hobbyist garages to professional machining shops. Its 7/16‑inch capacity is ideal for small‑to‑medium diameter workpieces, making it a versatile choice for tasks such as model engineering, prototype development, and precision component fabrication. The hand‑powered design means it can be used on battery‑operated portable lathes, providing flexibility for on‑site repairs or field work where electrical power may be limited.

When paired with the three 3/4 ER20 TTS tool holders, users gain the ability to quickly mount and dismount tools such as carbide inserts, drill bits, and turning tools. This rapid change capability is especially valuable in production runs where tool wear must be addressed promptly to maintain tolerances. The set’s high‑precision collet nut ensures that each tool remains firmly seated, reducing vibration and improving surface finish quality across a broad range of materials, including aluminum, brass, and mild steel.

FAQ

What lathe sizes are compatible with this 7/16 collet chuck?

The 7/16‑inch collet chuck is compatible with most standard lathe models that accept ER20 collets, including both bench‑top and portable units. It works well on machines ranging from 5‑inch to 12‑inch swing capacities, provided the spindle taper matches the ER20 standard.

Can the collet nut be replaced if it wears out?

Yes, the collet nut is a replaceable component. iCarbide offers spare nuts that match the original specifications, and the replacement process is straightforward: simply remove the worn nut and install the new one using the provided wrench. This design extends the overall service life of the chuck set.

Is the storage case suitable for shipping multiple sets together?

The case is designed to hold a single set securely, but multiple cases can be stacked or placed side‑by‑side in a larger shipping container. The robust exterior and foam interior protect each set from impact, making it an ideal solution for bulk orders or inventory management.

What materials can I safely machine with this chuck?

The chuck’s high‑precision design and stable clamping make it suitable for a variety of non‑ferrous and mild‑steel materials, including aluminum, brass, copper, and low‑carbon steel. For very hard alloys, users should ensure the cutting tool is appropriate for the material to avoid excessive tool wear.

How do I maintain the chuck for optimal performance?

Regular maintenance includes cleaning the collet and chuck body to remove metal chips, applying a light coat of machine oil to the moving parts, and periodically checking the collet nut’s torque settings. Following these simple steps will keep the chuck operating at peak precision and extend its service life.
