Drill Bits
BUYING GUIDE
How to Select Drill Bits
PerfoMax supplies rock drill bits for mining, quarrying, tunneling and construction drilling applications. This collection helps B2B buyers match bit geometry and connection to the drilling system and ground condition. Selection should be based on the required hole diameter, rock hardness and abrasiveness, drilling method, rod interface and the performance target for penetration, service life and total drilling cost.
How to select: start with the connection used by the drill rod or existing drilling string, then confirm bit diameter and face or cutting profile for the application. A bit that fits physically is not always the best operating match, so existing model references, worn-tool photos and target hole information are useful when checking compatibility. For repeat purchasing, consistent specification, quantity and packaging requirements can also be confirmed before quotation. If multiple diameters or profiles are needed, list them separately so the commercial offer remains clear.
Review compatible drill rods and pneumatic rock drills when building a complete system. Quotations can be prepared by specification, quantity, Incoterm and destination. If you are unsure which bit to use, send your drilling conditions for a recommendation and B2B quotation.

Select Rock Drill Bits by Interface, Diameter and Rock Response
Start with the drill rod and connection. For the current H22 tapered range, verify the 11° taper, socket dimensions, required hole diameter, flushing and rock behavior before choosing chisel, cross or button geometry.
| Buying path | What must be confirmed | Relevant PerfoMax page |
|---|---|---|
| 11° chisel bit | Confirm H22 rod, 11° taper, socket fit, diameter and sharpening practice | 11° taper chisel bits |
| 11° cross bit | Confirm the same interface first, then compare face geometry for the rock and hole | 11° taper cross bits |
| Taper button bit | Confirm diameter, exact taper angle, button profile and compatibility with the rod | H22 taper button bits |
Information to include in your RFQ
- Drill model and rod shank
- Exact taper angle and socket dimensions
- Required hole diameter
- Rock hardness, abrasiveness and fracture pattern
- Flushing method, quantity and destination
