Function of the 1/4" Collet

The 389244-00 Collet is designed to:

• Securely hold 1/4-inch shank cutting bits
• Maintain proper bit alignment during operation
• Reduce vibration and bit movement
• Provide consistent clamping force
• Support accurate plunge and freehand cutting
• Restore the original factory bit retention system

Using a genuine OEM replacement collet helps maintain cutting precision and reliable tool performance.

Common Signs Replacement Is Needed

Replace the collet if you notice:

• Cutting bits slipping during operation
• Difficulty tightening or releasing bits
• Excessive bit runout or vibration
• Cracked, worn, or deformed collet
• Poor cutting accuracy
• Visible wear on the clamping surfaces

A worn or damaged collet can reduce cutting precision and may prevent the bit from being held securely.

Installation & Service Notes

Disconnect the cut-out tool from the power source or remove the battery before servicing.

Remove the collet nut and existing 389244-00 1/4" Collet, then inspect the spindle threads and collet nut for wear or debris. Clean the spindle and install the replacement collet in the correct orientation before reinstalling the collet nut. Insert a compatible 1/4-inch shank bit fully, then tighten the collet nut securely according to the tool's operating instructions. Verify that the bit is properly centered and securely clamped before operating the tool.

Important: Always verify your cut-out tool model and original part number before ordering. Replace worn collets promptly to maintain safe bit retention and accurate cutting performance.

Maintenance Recommendations

• Keep the collet and spindle free of dust and debris.
• Inspect the collet regularly for wear or deformation.
• Clean the clamping surfaces before installing cutting bits.
• Avoid overtightening the collet nut.
• Replace worn collets that no longer grip bits securely.
• Use genuine OEM replacement parts to maintain factory fit, secure bit retention, and long-term cut-out tool performance.
