All steel cross bits are the economical drilling bit for soft to medium-hard formations: the cross-shaped head is machined entirely from high-strength, heat-treated steel, with no carbide inserts to pay for where extreme wear resistance is not required. Sizes run 1 in. through 4 in. in H, D and E threads for limestone, sandstone and similar ground.
The machined steel edges resharpen multiple times to stretch bit budgets on short blastholes, rock bolting and shallow well work, and air or water flushing holes keep cuttings clearing. These bits run on the same hex shanked drill steel as the rest of our rock drill bit range; when the ground turns hard or abrasive, a carbide tipped cross bit in the matching thread is the longer-wearing choice the buyers guide to rock drill bits covers where each earns its cost.
- Bit diameters from 1 in. to 4 in. in H, D and E threads
- Machined entirely from high-strength, heat-treated steel no carbide inserts
- Steel cutting edges can be resharpened multiple times to reduce cost per foot
- Cross configuration balances cutting action for straight holes and even wear
- Air or water flushing holes clear cuttings and prevent overheating
- Best in soft to medium-hard formations: limestone, sandstone and weak rock layers
- Applications: short blastholes, rock bolting, slope stabilization and shallow well drilling
