Coal mining bit Description:
Tough crushing conditions call for a tougher cutting tool. Tydrillbits supply carbide tipped coal cutter picks in 38mm, 51mm, and 52mm sizes.
1. They're designed with large collars for extra block face protection.
2. Extreme wear and abrasion resistance are designed into the block with wide bodies that wear in line with the carbide tip.
3. Plug and narrow-bottom style solid carbide tips are highly impact resistant in crushing conditions.
Advantages of coal mining bit:
1. More wear resistant and impact resistance of cutter picks body pyramid. Protect alloy head won't fall off because of excessive wear and tear.
2. Enhanced the mechanical strength, the perfect integration of both of the hardness and toughness, especially the
Combination property of coal cutter picks has greatly improved, at the
Part of the connection which is the handle and the cone, anti-shear capacity is enhanced, to avoid the fracture phenomena.
3. Melting and Cladding layer are close-grained and smooth, the resistance is small, coal into blocks rate is high.
4. Melting and cladding layer will not generate sparks when cutter pick is colliding the rocks. It is more safely to work in highly gassy mine.
