Zippered tool bag is a type of tool bag that features a zipper closure, rather than an open top or drawstring closure. The zipper allows for secure and easy access to the contents of the bag, while also providing additional protection for the tools inside.
Zippered tool bags can come in a variety of sizes and materials, ranging from small pouches designed to hold a few small tools to larger bags that can hold multiple tools and accessories. They are often made of durable materials such as nylon or canvas, with reinforced stitching and heavy-duty zippers to withstand the wear and tear of daily use.
Zippered tool bags are popular among professionals and DIY enthusiasts alike, as they provide a convenient way to organize and transport tools without the risk of them falling out or getting lost. They can be easily carried by hand or using a shoulder strap, and some models even feature additional pockets and compartments for storing smaller items or accessories.

Shaft end threaded bottom hole simple drilling mold
When we machined two M6 threaded holes in the crankshaft (Fig. 1), we used a simple drill groove to meet the accuracy and speed requirements of the production line. Since the φ45mm and the keyway (CC diagram) have been machined to the size before drilling, the drill is oriented with the A surface, the keyway and the φ45mm outer circle as the positioning reference.
