Different rock hardness drilling button bit ST58 with Dia 102mm ,
benching and long hole drilling
Describtion
This type of bit is well known for its high wear resistance on
medium-hard to hard abrasive rock formations (between 200 Mpa to
260 Mpa compressive strength). Featuring spherical tungsten carbide
inserts that is known to have strong configuration against carbide
fracture. Recommended for eliminating hole deviation. Used in
benching and long hole drilling
.• Bit face design is ideal for soft to medium rock formations
• With Retrac Wings to help guide the bit in and out of the hole
• Effective in straight hole drilling
