FAQ

Q: What's the difference between a copper taper drill bit and a regular twist drill bit? 
A: The key differences lie in the cutting edge and flute design. Copper taper drill bits have sharper cutting edges and wider flutes, suitable for soft metals like copper and aluminum to prevent chip adhesion. Regular twist drill bits have larger cutting angles and narrower flutes, which tend to cause chip clogging and excessive burrs when processing soft metals.

Q: Why does a copper taper drill bit stick to the workpiece when drilling copper? 
A: The main causes are excessively high cutting speed, no cutting fluid applied, or a dull drill bit edge, which leads to softening and adhesion of copper chips.

Q: Can copper taper drill bits be used to process stainless steel or wood? 
A: Not recommended. Their cutting edge hardness and angle are optimized for soft metals. Drilling stainless steel will easily wear or chip the bit, while drilling wood may cause splitting and poor chip removal.

Q: How to extend the service life of a copper taper drill bit? 

A: Maintain medium-low speed cutting, use cutting fluid throughout the process, clean copper chips from the edge in a timely manner, and store the bit in a moisture-proof environment.

Q: How to choose between a straight shank and a taper shank copper taper drill bit? 
A: Straight shanks are compatible with electric hand drills and small bench drills, ideal for small-diameter drilling. Taper shanks require heavy-duty bench drills or radial drills, offering a more stable grip and suitable for large-diameter, high-load drilling tasks.
