Upínacie skľučidlo Makita 763620-8, veľkosť skľučidla 6 mm

Collet chuck Makita 763620-8, 6 mm collet size is a replacement accessory designed to hold round-shank bits and router or milling accessories with a 6 mm shank. It provides concentric clamping and stable tool retention for compatible Makita power tools that accept this style of collet chuck. The component is intended for use in routing, light milling and drilling operations where precise alignment and repeatable clamping are required.

Advantages

The 6 mm collet size offers a direct, secure grip on standard round shank bits without the need for adapters, reducing runout and improving accuracy. Its construction supports consistent clamping force and stable rotation at typical router and spindle speeds. As a replaceable chuck, it restores or upgrades tool holding on compatible Makita machines, helping maintain concentricity and minimizing bit wobble during operation.

Suitable for

• Holding 6 mm round shank router bits and cutters
• Light milling and trimming tasks on wood, plastic, and composite materials
• Workshop and professional routing where accurate concentricity is needed
• Replacing worn or damaged collets on compatible Makita tools

Key specifications

• Collet size: 6 mm (for round shank bits)
• Type: collet chuck for router/spindle-style tools
• Function: concentric clamping and secure tool retention
• Compatibility: designed for Makita routers and spindles that accept this collet style
• Typical applications: routing, trimming, light milling

How to use

Ensure the power tool is switched off and disconnected from the power source before installing the collet chuck. Remove the existing chuck or collet following the tool manufacturer's instructions, then insert the 6 mm shank of the bit into the collet and tighten securely using the appropriate wrench or tightening method recommended by the tool maker. Verify the bit is fully seated and that clamping is even before restoring power. Periodically check tightness during use and re-tighten when the tool is at rest to maintain safe operation.

Recommendations

Use correctly sized 6 mm round-shank bits to ensure proper clamping. Avoid overtightening, which can damage the collet or the bit; tighten to the torque level advised by the tool manufacturer. Inspect the collet and shank for wear or debris before each use and replace the collet if signs of deformation or excessive wear are present. Follow all safety instructions for your router or spindle, including appropriate speeds for the installed bit and workpiece material.
