The 12-degree tapered button bit is a heavy-duty rock drilling tool built for hard rock and deep-hole drilling. Its steep taper profile delivers the strongest self-locking grip on the drill rod, preventing bit drop under high-impact, deep-hole conditions where 7-degree and 11-degree bits may loosen. It pairs with H22 hexagonal tapered drill rods on YT23, YT24 and YT28 air leg rock drills, in a full diameter range of 26-42mm.
