Compatibility and Required Interfaces
Cutting Face and Taper Interface
Concentrated Single-Edge Cutting
The carbide chisel edge concentrates impact along a defined line while the bit body transfers percussion from the tapered rod.
Buyer value
A simple cutting profile can be practical for small-diameter drilling when the rock and drill string are correctly matched.
Selection condition
Performance depends on socket fit, brazing, flushing, bit condition and rock formation.
Application Scenarios
- Small-diameter blast-hole drilling
- Quarry and mine development
- Compatible hand-held or air-leg drill strings

Frequently Asked Questions
How do I confirm an 11° chisel bit will fit my rod?
Confirm the rod is H22 with an 11° taper, then compare the socket dimensions and insertion depth. Photos or a drawing of the current rod and bit help prevent mixing taper systems.
Matched Tapered Drilling System
Use with a verified H22 × 108 mm rock-drill interface, 11° tapered rod, compatible drill and flushing arrangement.
