[0002] A drill is a chip removal tool for workpieces of nonferrous metals, ferrous metals or non-metallic materials, such as drilling through holes, expanding holes, blind holes, step holes, chamfering, etc. Commonly used drills include twist drills, flat drills, center drills, deep hole drills and U drills, etc. They are generally made of carbon steel SK or high-speed steel SKH2, SKH3 and other materials through milling or rolling, quenching, tempering heat treatment and grinding.

[0003] The patent specification with announcement number CN216065693U discloses a precisely positioned drill bit for processing automobile ABS valve bodies. The drill bit is welded to a carbide tool bar through high-frequency welding, is wear-resistant and durable, increases the service life of the tool, reduces the friction coefficient between the tool and the workpiece, increases the feed of the tool, and improves the cutting performance of the tool. It also uses irregularly distributed cutting edges and cutting edge main cutting surfaces of varying heights to effectively avoid tool vibration. By setting a larger top angle than a standard drill bit, the angle is larger and more stable, and the cutting edge uses a composite back angle setting of a cutting back angle and a guide back angle, which plays a core-fixing role during processing, ensuring accurate positioning and no deviation when just entering the hole for processing.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed automobile ABS valve body processing drill bit with precise positioning has the following problems: since the drill bit needs to process automobile parts of different types and sizes during use, and when the drill bit cannot be adjusted, it is necessary to replace drill bits of different lengths when facing the processing of automobile parts of different sizes, which will slow down the efficiency of automobile processing during use. In view of this, an anti-sticking alloy drill bit for automobile processing is provided to overcome the above-mentioned defects. Utility Model Content
