Precision 16C Collet (Round, Hex, Square) | Heavy-Duty CNC Lathe Tooling

[Product Overview]

The 16C Collet is the heavy-duty standard for CNC turning centers and lathes. While similar in design to the 5C collet, the 16C offers a significantly larger head diameter and body, allowing it to hold larger diameter bar stock directly through the spindle. It is widely compatible with major lathe brands (such as Hardinge, Haas, Mazak) equipped with 16C spindles, making it essential for high-production environments.

[Key Features & Advantages]

• Larger Capacity: Supports bar stock diameters up to 1-5/8" (1.625" or ~42mm), compared to the 1-1/16" limit of 5C collets, greatly expanding your machining capabilities.

• Versatile Profiles: We manufacture a full range of shapes:

• Round: For standard cylindrical bars.

• Hexagon: For 6-sided stock.

• Square: For 4-sided stock.

• High Precision: Precision ground to ensure low runout (T.I.R.), critical for maintaining tight tolerances in CNC turning.

• Durable Construction: Made from high-grade alloy spring steel (65Mn or SUJ2), heat-treated to HRC 55-60 to resist wear and maintain spring tension over thousands of cycles.

• Internal Threads: Features standard internal threads to accept work stops, allowing for precise axial positioning of parts.

Frequently Asked Questions (FAQ) - OEM & Orders

Q1: What is the main difference between 5C and 16C collets?

A: The primary difference is size and capacity. 16C collets have a larger body and head, allowing for a maximum through-capacity of 1-5/8", whereas 5C collets max out at 1-1/16". 16C is used for heavier work on larger spindles.

Q2: Do you offer 16C Emergency Collets?

A: Yes! We supply 16C Emergency Collets with a soft steel or brass face. These can be bored out by the customer on their own machine to hold unique or stepped workpieces perfectly concentric to the spindle.

Q3: Can I order custom sizes or metric sizes?

A: Yes. While fractional inch sizes are most common for 16C, we can manufacture metric sizes (e.g., 20mm, 30mm, 40mm) and special decimal sizes upon request.

Q4: Are your collets compatible with Hardinge spindles?

A: Yes, our 16C collets are manufactured to standard industry dimensions and are fully interchangeable with Hardinge and other major brands of 16C collet chucks/spindles.
