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.
Chisel bit (42 Chisel bit ) Word broken drill bit for drilling, often with light internal combustion, electric, pneumatic and hydraulic rock drill] and [B22 drill pipe, coal mine tunnel in the rock drilling rock pore diameter D50mm less. The mining industry, the main varieties of small diameter drill bit rock drill hole used in the project.Hot models: 40 chisel bits, 42 bits chisel .

Chisel drill bit for rock drill application:
For light drills, rock drilling hole diameter 50mm or less, suitable for rock hardness is not high. Widely used in various types of mines and railways, highways, water conservancy construction of coal, iron ore, gold, copper, lead-zinc mine in tunneling.
