Tapered Button Bit

For the carbide button bit, we can provide Hemispherical shaped, parabolic shaped, conical shaped,round shank picks(for coal mining)

Steel material:42CrMo/Z780/45CrNiMov are available.

Customized drill bit is also available, please send us inquiry with requirement, then we'll recommend the suitable carbide drill bit and material for you.

Please observe that all button bits are manufactured over-sized 0,5–1,0 mm, meaning that for example a 36,0 mm bit is at least 36,5 mm as new. This is done because of the fast initial wear on button bits.

It is important to consider that the drilled hole could vary in size due to drilling conditions, drilling practices and ground formation.

Following are some items' specification, please contact us for more information.
