Collet/Arbor Dedra 07F073B, model 07F073B, shank 8 mm

Collet/Arbor Dedra 07F073B with an 8 mm shank is a mechanical accessory designed to secure compatible cutting tools, drill bits or rotary attachments in machines that accept an 8 mm shank. The part provides a concentric clamping interface between tool and spindle, reducing runout and enabling stable rotation for hobby and light professional applications such as drilling, milling, grinding or polishing with compatible rotary tools and attachments.

Advantages

This 8 mm shank collet/arbor is manufactured to provide a firm, repeatable clamping force and improved concentricity compared with non-clamped adapters. The compact design allows use in tight working spaces while keeping the tool axis stable during operation. Made for compatibility with typical lightweight rotary tool systems, it simplifies tool changes and helps maintain consistent machining results.

Suitable for

• Securing small cutting tools and drill bits with compatible mounts
• Rotary tool attachments for grinding, polishing and sanding
• Light milling operations on soft materials in hobby or small workshop settings
• Adapters where an 8 mm shank interface is required

Key specifications

• Shank diameter: 8 mm
• Function: collet-style clamping/arbor connection for rotary tools
• Compatibility: for tools and accessories designed to mate with an 8 mm shank interface
• Application range: hobby and light professional rotary tool operations (drilling, milling, grinding, polishing)

How to use

Insert the 8 mm shank into the machine spindle or adapter and secure according to the machine manufacturer's instructions, ensuring the collet is seated fully before tightening. Fit the cutting tool or accessory into the collet's mating bore, verify concentric alignment by hand rotation, then tighten to the recommended torque for your machine type. Perform a short test run at low speed to confirm stable rotation and absence of excessive vibration before normal operation.

Usage recommendations

Use the collet with tools and accessories intended for an 8 mm shank and avoid exceeding the recommended speeds and loads for your rotary tool. Regularly inspect the clamping surfaces for wear or debris and clean before use to maintain concentricity and secure holding. Replace the collet if signs of deformation or significant wear appear.
