[0002] The woodworking square hole drill is a special tool for making mortises and tenons for woodworking. The woodworking square hole drill can chisel rectangular grooves on wood. The processed grooves are smooth and high in precision, so it has been widely used in the field of woodworking processing.
[0003] When woodworking square hole drill bits are in use, their cutting edges are greatly worn out, and after the cutting edges become blunt, they cannot be repaired by manual grinding, so they are directly discarded. However, due to the high cost of woodworking square hole drill bits, directly discarding them will lead to excessive costs and excessive losses. Therefore, universal alloy files are usually used on the market to grind the cutting edges. However, when grinding woodworking square hole drill bits of various specifications, due to the use of universal alloy files, the cutting edges ground in this way will be irregular. Therefore, in subsequent use, the processed grooves do not meet the use conditions. Therefore, we propose a square hole drill blade repair alloy file. Utility Model Content
