Pinza de sujeción Bosch 2608570083 1/8 pulgadas con tuerca de fijación

Bosch collet 2608570083 is a 1/8 inch (approximately 3.175 mm) collet supplied with a clamping nut for use with compatible rotary tools. It is engineered to hold small-diameter shank bits securely, restoring proper bit retention and ensuring concentric rotation for drilling, grinding, carving and polishing operations. The metal construction and precision bore provide a tight fit for standard 1/8 inch accessories and help reduce runout during high-speed use.

Advantages

The collet and clamping nut combination delivers stable, concentric gripping of small shank bits to minimize vibration and improve finish quality. Precision-machined surfaces ensure consistent clamping force and long service life under normal operating conditions. The ready-to-install design makes the part suitable for fast replacement, helping to restore tool performance and secure accessories reliably.

Suitable for

• Holding 1/8 inch (≈3.175 mm) shank drill bits and burs
• Rotary tool tasks such as grinding, carving, sanding and polishing
• Replacement of worn or damaged collets in compatible rotary tools

Key specifications

• Collet diameter: 1/8 inch (approx. 3.175 mm)
• Includes clamping nut for secure attachment
• Material: precision-machined metal construction
• Designed for use with compatible rotary and multi-tools that accept 1/8 inch collets
• Supports high-speed rotational applications with reduced runout

How to use

To install, remove the existing collet assembly from the tool spindle, insert the 1/8 inch bit into the collet bore, then thread and tighten the clamping nut to the manufacturer’s recommended torque or until the bit is held firmly. Ensure the bit is seated to the required depth before final tightening to maintain concentric rotation. Periodically inspect the collet and nut for wear or damage and replace if clamping performance deteriorates.

Recommendations

Use only correctly sized 1/8 inch shank accessories and follow the rotary tool manufacturer’s safety and maintenance instructions. Avoid overtightening the clamping nut to prevent damage to the collet or accessory shank; if excessive runout or slipping occurs, replace the collet assembly.
