Yichang Shipyard "shipbuilding transformation" work started
Drill bits are cutting tools used to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.

In the afternoon of the day, Changhang Heavy Industry Yichang Shipyard held a mobilization meeting for “shipbuilding and transformationâ€, and nearly 100 people attended the conference. The convening of the conference marked the full launch of the “shipbuilding transformation†work of Changhang Heavy Industry Yichang Shipyard.
At the meeting, the director and chief engineer Zeng Xiaohu made a nearly two-hour mobilization report. He emphasized that “fine shipbuilding†work “fine management is the foundation, leadership attention is the key, technical design is the leader, production preparation is the soulâ€; It is required that the whole plant will not "arguing, not discussing, and not rigidizing" the "shipbuilding transformation" work, and will continue unswervingly in accordance with the "shipbuilding transformation model" work plan.
Under the support of Changhang Heavy Industry, Changhang Heavy Industry Yichang Shipyard's “shipbuilding transformation model†has been gradually implemented two years ago. According to the “decomposition and combination principle†of the system engineering, it has clearly produced seven major production processes and realized “intermediate productsâ€. "Oriented grading manufacturing system. In accordance with the requirements of “ship-making transformationâ€, the tire frame was re-reformed, and the “planar tire frame clamping method†and “curved tire frame clamping method†hull structure manufacturing process (reported patent technology) were applied and controlled. The core technology of steel plate welding deformation.
Drill bits come in standard sizes, described in the drill bit sizes article. A comprehensive drill bit and tap size chart lists metric and imperial sized drill bits alongside the required screw tap sizes. There are also certain specialized drill bits that can create holes with a non-circular cross-section.
