Big Horn 19694 1/2" Router Collet Replaces Porter Cable 42950. Can be used in two ways: as a straightforward replacement collet, or to enable a router to handle shank bits measuring 1/2 In. Its clever design also allows the router bit, collet, and collet nut to be removed as a single, unified unit, which helps prevent any time-wasting, immovable bits that won't budge.

Features:

• For use with 1/2" shank router bits
• 1/2" Router collet for use as a replacement or adapter
• Auto-release design prevents "frozen" bits
• Accepts 1/2" shank router bits
• Auto-release design prevents router bits from sticking in the router
• Designed to minimize bit run-out and enhanced robustness
• Helps decrease the amount of lost bits
