Chuck adapter Rittal 4050.826 — compatible chuck size 6.1–7 mm, stainless steel

Rittal 4050.826 is a stainless-steel chuck adapter designed to provide a secure interface between a tool spindle and a compatible chuck size of 6.1–7 mm. As a single-piece attachment accessory, it adapts drill bits and small tooling to machines that require this specific clamping range. The adapter is intended for workshop and industrial use where steel construction and reliable clamping are required.

Advantages

The stainless-steel construction offers corrosion resistance and mechanical durability for repeated use in typical workshop and light industrial environments. The adapter provides a straightforward mechanical interface that helps maintain concentricity and reduces runout when clamping drill bits within the 6.1–7 mm range. Being a single, compact component, it is simple to install and replace without modifying the primary tool spindle or chuck.

Suitable for

• Adapting drill bits and small tooling to spindles requiring 6.1–7 mm chuck fit
• Light to medium machine shop operations and maintenance tasks
• Workshop setups where a stainless-steel adapter is preferred for durability
• Industrial environments that require a robust clamping accessory

When it may not be suitable

This adapter is intended for use within the specified clamping range of 6.1–7 mm; it is not suitable for tooling outside this diameter range. It is a passive mechanical accessory and does not provide active features such as vibration damping or precision collet-level concentricity guaranteed for high-precision micromachining. For heavy-duty cutting or unusually high torque loads, users should verify compatibility with their specific machine and tooling.

Key specifications

• Type: Chuck adapter / adapter for drill bits
• Material: Stainless steel
• Compatible chuck size: 6.1–7 mm
• Quantity: 1 piece

How to use

Install the Rittal 4050.826 adapter by inserting it into the machine spindle or existing chuck according to the machine manufacturer’s guidance, then insert the drill bit or tooling into the adapter and tighten the chuck to the appropriate torque. Ensure the tool is seated properly and the clamping surfaces are clean before use. Check runout and secure fastening after initial installation; perform a test cut or drill at low speed to confirm correct alignment before normal operation.

What to consider before purchase

• Verify your spindle or chuck accepts an adapter of this type and dimensions (6.1–7 mm clamping range)
• Confirm stainless-steel material is suitable for your operating conditions (corrosion resistance, hardness)
• Ensure the adapter’s mechanical fit and rated torque match the intended tooling and machine

Usage recommendations

Use the adapter for general drilling and reaming tasks within the specified diameter range, perform regular inspections for wear or surface damage, and avoid exceeding the machine’s recommended torque settings to prolong service life.
