Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Drillers choose tapered button bits for faster drilling penetration rate. Different taper sizes have different characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning.

 


Chisel bit Feature:

1, use of high-quality steel, alloys, high toughness and high wear resistance, high production efficiency.

2, manufacturing process is simple, easy to use, low price, strong adaptability to rock performance.

3,situation can rock drilling operations or seam, concrete, etc., the change can ease the drilling status of a sudden, so that drilling operations stable, even when a large grain chips, drilling efficiency is not caused by lower bit.
