Step tool

Abstract

The invention relates to a step tool. The step tool comprises a tool shank and a tool bit, wherein the tool shank is connected to the tool bit; the tool bit comprises a central drill, a drill bit, a milling cutter and a chamfering knife, the central drill, the drill bit, the milling cutter and the chamfering knife are coaxially arranged, and are distributed in a stepped mode; and the central drill, the drill bit, the milling cutter, the chamfering knife and the tool shank are sequentially connected together. The step tool can effectively solve a cutter spacing deficiency phenomenon, and can process two holes and chamfer once; and meanwhile, various tool functions are combined, so that occurrence of burrs at mutually crossed parts, during processing, of tools is avoided, and therefore, processing efficiency is obviously improved, and product processing cost is reduced.

Description

technical field [0001] The invention relates to the field of drilling tools, in particular to a stepped tool. Background technique [0002] The existing equipment on the market has only three power heads, and high-end equipment can only have four power heads. According to the normal practice, five power knives are required to process. figure 2 In other words, only four processes can be processed first, and one process is left for the milling machine to process one piece, and the milling machine processes one process, the shape tolerance and appearance cannot meet the requirements of the drawing, and this product is used for optical communication. The burr requirements are very high, and this processing method cannot meet the drawing and application requirements. If you purchase high-configuration equipment, not only the equipment price is extremely high, but also the delivery period of the new equipment is long, which cannot guarantee the delivery date of the customer's orde...
