उत्पाद का वर्णन
Product Overview The 7-degree tapered button bit is a rock drilling tool designed to pair with H22 hexagonal tapered drill rods on YT23, YT24 and YT28 air leg rock drills. Its shallow 7-degree taper profile locks the bit onto the rod through impact self-tightening, allowing quick bit changes and low drilling resistance. Available in a full diameter range of 26-42mm, it is widely used for anchor bolt drilling, quarrying and shallow-hole drilling in soft to medium rock
