Premium Material: The hex drill bit holder is made of high-quality, sturdy, and impact-resistant ABS material, offering oil resistance, stain protection, and wear resistance, making it more resistant than ordinary plastic cases. Magnetic Base: The optimized magnetic design ensures the base attaches firmly, securing parts without dropping them into your toolbox. It's strong enough to stay in place even when turned upside down, yet allows easy removal. (More reliable than traditional spring or elastic band designs) Easy Access: The 37-hole drill bit organizer is compatible with 1/4-inch bits, allowing centralized storage of all your drill bits. The open-top design (no lid) ensures all bit sizes remain clearly visible, with ample space for various driver units and accessories—eliminating the hassle of repeatedly opening and closing lids, and reducing search time. Tool Storage: Featuring a slim, compact magnetic design, this tool holder is portable and can be taken anywhere. With 37 holes, it effectively solves tool storage problems, making your work easier and more efficient. It also makes a great gift for family or friends. Package Contents: You will receive eight 37-hole drill bit organizers, each measuring approximately 7.05 x 1.22 x 0.79 inches / 17.9 x 3.1 x 2 cm. The set includes two organizers each in red, green, blue, and orange—different colors suit different occasions, and the vibrant colors make it easier to locate your tools.
