The Bit Buddy from Ernst is a premium organiser designed to hold a wide variety of hex bits in one convienent place. Taper lock holes provide a secure hold so tools won't fall out and it provides just the right resistance so tools can also be easily retrieved. The rare earth magnets used in the base of the rail holds strong on metal surfaces, pulls through drawer liner, and even holds on vertical sides or upside down. The 30 Tool Bit Buddy holds long, medium, and short bits. Long bits lay flat and short bits are held upright. A specially designed hole can also fit a 3/8" drive chuck. Compact and convenient storage is great for in the toolbox, mounted on the side, or on the go. Made in USA.
