The shallow insert carbide tipped cross bit puts a lower-profile, cross-shaped cutting face on soft to medium-hard rock, where reduced face resistance converts directly to faster penetration. Optimized carbide tip angles keep the cut efficient without giving up hole straightness, air or water flushing holes keep the shallow face clear, and H-thread sizes run from 1-3/8 in. through 2 in.

In limestone, shale and consolidated formations the shallow profile out-drills a standard-depth head; when the ground hardens, the full-insert carbide tipped cross bit is the tougher choice. Either style threads onto the same H-thread hex shanked steel for sinker and jackleg work see all rock drill bits, or let the buyers guide match head profile to rock.

• H-thread sizes from 1-3/8 in. through 2 in.
• Low-profile shallow cross design reduces face resistance for higher drilling speeds
• Optimized carbide tip angles hold cutting efficiency and hole straightness
• Tungsten carbide inserts on a heat-treated alloy steel body
• Air or water flushing holes clear debris and reduce overheating
• Best in soft to medium-hard rock: limestone, shale and consolidated formations
• Applications: surface blastholes, rock bolting, shallow wells and slope stabilization
