The Big Idea Design Spinline Upgrade Kit converts your compatible Bit Bar Inline into a smooth spinning driver, making repetitive screws and detailed maintenance faster and more comfortable. It’s an ideal upgrade for knife maintenance, electronics, EDC gear adjustments and other jobs where quick, controlled driver rotation makes a difference.

Designed to work with the entire Bit Bar Inline platform, the Spinline Kit adds extra functionality to a driver you already carry without requiring a completely separate tool.

• Includes: Spinline conversion kit only. This is the top spinner only. Bit Bar Inline is purchased separately. Compatible with Bit Bar Inline, Inline Max and Inline Mini.
• Installs with a single included T8 screw. Since a T8 bit ships with every Bit Bar Inline model, installation is easy.
