Die Grinder Proxxon 23050 MicroSpeeder with 13 mm joint — rotary tool attachment

Proxxon 23050 MicroSpeeder with a 13 mm articulated joint is a compact die grinder attachment designed to extend the reach and angular access of compatible rotary tools. The attachment couples to a Proxxon rotary drive and transfers rotary motion to small grinding, polishing or cutting bits while allowing work in confined or angled spaces. It is intended as an accessory for precision tasks such as model making, metal finishing, and detail work where a straight tool cannot reach conveniently.

Advantages

The MicroSpeeder's 13 mm joint provides improved maneuverability and enables access to narrow or awkward positions without changing the primary tool. Its compact construction maintains stable transmission of rotary motion to small-diameter bits, and its compatibility with Proxxon rotary tools ensures consistent performance. The attachment reduces the need for manual repositioning and facilitates controlled, precise surface work.

Suitable for

• Model making and scale hobby work
• Fine metalworking and deburring
• Polishing small areas and finishing details
• Cutting and grinding in confined or angled spaces
• Jewellery repair and precision crafts

When it may not be suitable

The MicroSpeeder is intended as an accessory for rotary tools and is not a standalone power tool. It is built for small-diameter bits and precision tasks rather than heavy material removal or high-torque industrial grinding. For prolonged high-load applications or large-diameter grinding, a dedicated high-power grinder or angle tool is more appropriate.

Key specifications

• Attachment type: die grinder / rotary tool accessory
• Joint diameter: 13 mm articulated joint for angled access
• Intended use: transmission of rotary motion to small grinding, polishing and cutting bits
• Compatibility: designed for use with Proxxon rotary drive tools
• Application areas: precision finishing, deburring, polishing, cutting in tight spaces

How to use

Attach the MicroSpeeder to a compatible Proxxon rotary tool according to the tool manufacturer's instructions, ensuring secure coupling. Fit an appropriate small grinding, cutting or polishing bit into the attachment and set the rotary tool to the recommended speed for the bit and material. Guide the bit to the working area with light, steady pressure, using the articulated joint to reach angled or confined spots. Pause periodically to inspect the work and avoid excessive heat buildup.

What to consider before purchase

• Confirm compatibility with your Proxxon rotary tool model.
• Check bit diameter and whether the attachment accepts the specific bits you use.
• Assess whether your tasks require low-torque precision work rather than heavy material removal.
• Consider access needs—this attachment is designed specifically for tight or angled spaces.

Usage recommendations

Use appropriate safety equipment such as eye protection and dust extraction when grinding or cutting. Select bit type and speed according to material and task, and allow the attachment and bit to cool during extended operations to maintain consistent performance and prolong service life.
