Collet Chuck Hazet 849IG-6.3, 6.3 mm

Hazet 849IG-6.3 collet chuck is a precision toolholding accessory designed to securely hold tools with a 6.3 mm shank diameter. Manufactured to provide stable clamping and high concentricity, this collet chuck supports drilling, milling and general machining operations where consistent positioning and repeatability are required. The compact design suits both workshop and industrial environments and integrates with compatible spindles and adapters to form a reliable toolholding system.

Advantages

The collet chuck ensures uniform radial clamping pressure around the 6.3 mm tool shank, reducing runout and improving machining accuracy. Its construction provides repeatable tool retention for series production and routine tool changes. The precision fit minimizes vibration and contributes to longer tool life. The design is compact for easy installation and offers mechanical stability suitable for varying machining loads.

Suitable for

• Drilling operations with 6.3 mm shank drills
• Milling and finishing with 6.3 mm shank cutters
• Light to medium machining and reaming tasks
• Workshops and industrial toolholding setups requiring accurate concentricity

Key specifications

• Nominal collet diameter: 6.3 mm
• Tool shank compatibility: 6.3 mm straight shanks
• Function: precision collet chuck for secure radial clamping
• Application: drilling, milling, reaming and general machining
• Design: compact, suitable for integration with standard spindles and adapters

How to use

Insert the appropriate 6.3 mm shank tool into the collet and ensure the tool end rests fully against the collet seat. Thread or secure the collet chuck to the spindle or adapter according to the machine manufacturer’s mounting procedure. Tighten to the recommended torque to achieve full clamping force and verify concentricity before machining. For tool changes, loosen the chuck, remove the tool, and repeat the insertion and tightening steps. Follow machine and tooling safety procedures throughout the process.

Usage recommendations

Use the collet chuck with tools that match the 6.3 mm nominal diameter and avoid using worn or damaged shanks to maintain concentricity. Regularly inspect the collet and chuck surfaces for wear, clean of chips and coolant residue, and lubricate threads or contact surfaces as directed by machine guidelines to preserve clamping reliability.
