Chuck key for 200 mm chuck, 4-sided square 11 mm – RÖHM

A Chuck key for 200 mm chuck engineered for secure tightening and release of lathe chucks, featuring a spring-mounted sleeve to avoid the key being left in the chuck

• Spring-mounted sleeve prevents key sticking
• 11 mm four-sided square drive
• Designed for 200 mm chucks
• Positive insertion square for secure fit

Safer operation that reduces interruptions

The integrated spring-mounted sleeve is designed to prevent the key from becoming lodged in the rotating chuck, a common cause of unscheduled stops. This safety feature reduces the risk of incidental damage to the workpiece and the machine spindle, contributing directly to reduced downtime and fewer workflow interruptions. For workshops that value continuous production and predictable cycle times, this mechanical safeguard delivers clear operational benefits without adding complexity to routine clamping tasks.

Positive engagement for reliable torque transfer

The 11 mm four-sided square drive provides a positive mechanical interface between key and chuck, improving torque transfer and minimising slippage compared with round pin designs. This characteristic supports faster, safer tightening and loosening cycles and helps maintain consistent clamping force across repeat operations. The result is a more dependable clamping process that supports quality assurance and efficient use of machine time.

Designed to fit common workshop chucks and workflow

Built to match the dimensions of a 200 mm chuck, the tool integrates into standard machining stations and can be stored alongside other hand tools without occupying excessive space. The insertion square ensures a secure engagement that gives operators confidence during repetitive tasks. Supplied as a single unit, the item is straightforward to add to procurement lists and to keep as a standby critical for lathe maintenance and set-up operations.

FAQ

Is this key compatible with any 200 mm chuck? The RÖHM chuck key is designed for use with chucks of 200 mm nominal diameter and a corresponding square drive; compatibility depends on the chuck drive interface matching the 11 mm square

How does the spring-mounted sleeve work in practice? The spring-mounted sleeve holds the key in its engaged position and releases under light axial movement, preventing the key from being unintentionally left in the chuck during operation

What maintenance does the key require? Periodic inspection for wear at the square drive and light lubrication of moving parts will keep the chuck key performing reliably; replace if the insertion square shows deformation

Can the key be used on stationary chucks and removable chucks? The tool is intended for chucks that accept an 11 mm insertion square; both stationary and removable chucks with matching interfaces are suitable

Does the product include any additional accessories? The delivery comprises the chuck key as supplied (packaging unit: 1); no additional accessories are listed
