Chuck adapter Rittal 4050.825 — chuck adapter for 5.1–6 mm, stainless steel

Rittal 4050.825 is a stainless-steel chuck adapter engineered to accept drill chucks with shank diameters between 5.1 and 6 mm. Designed as an accessory for drilling and machining fixtures, this adapter allows standard chucks to be mounted in Rittal tool setups, providing a compact mechanical interface for reliable retention of compatible drill shanks in industrial and workshop environments.

Advantages

The stainless-steel construction offers corrosion resistance and dimensional stability under normal workshop conditions. Its compatibility range of 5.1–6 mm covers common small-diameter drill shanks, making it suitable for precise drilling tasks. The single-piece design simplifies installation and replacement, and the adapter is intended to integrate directly with Rittal fixtures to reduce the need for custom machining.

Suitable for

• Mounting standard drill chucks with 5.1–6 mm shanks
• Use in industrial drilling fixtures and machining stations
• Workshop repairs and retrofitting of existing Rittal tool setups
• Precision small-diameter drilling and light machining tasks

When it may not be suitable

This adapter is intended specifically for drill shanks within the 5.1–6 mm range; it will not securely hold shanks outside that diameter interval. It is a mechanical adapter and does not include any driven or powered components—applications that require integrated power transmission, specialized torque coupling, or nonstandard mounting interfaces may require different accessories.

Key specifications

• Material: stainless steel
• Supported shank diameter: 5.1–6 mm
• Quantity: 1 piece
• Application: chuck adapter for drilling and machining fixtures

How to use

Install the adapter into the designated holder or spindle of the Rittal fixture, ensuring the seating surfaces are clean and free of debris. Insert the compatible drill chuck or shank into the adapter and secure it according to the fixture's retention method. Check alignment and runout where precision is required, and perform a trial cut at low speed to confirm secure clamping before normal operation.

What to consider before purchase

• Confirm your drill shank diameter falls within 5.1–6 mm
• Verify compatibility with your specific Rittal fixture or mounting interface
• Consider material requirements—stainless steel for corrosion resistance
• Ensure the adapter's mechanical retention method matches your application needs (static holding vs. rotating driven use)

Usage recommendations

Regular inspection of seating surfaces and periodic cleaning will help maintain clamping accuracy. For precision work, verify runout with an appropriate gauge and avoid using the adapter with oversized or undersized shanks to prevent slippage or damage.
