Explosion Proof Design Rotary Bit for Safe Operation in Gassy and Coal Seam Mining Environments

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.

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.

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.

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.

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.
