Technical Review Scope
Configuration and Quotation Guidance
H22 taper button bit configuration inquiry for 30, 32, 34, 36, 38 and 40 mm diameter references. Diameter alone does not define a complete bit configuration.
Configuration identity: PFM-TB30, PFM-TB32, PFM-TB34, PFM-TB36, PFM-TB38 and PFM-TB40 are diameter inquiry references only, not complete orderable SKUs. H22 identifies the 22 mm hex rod body; it does not define taper compatibility. Before a model-specific quotation can be technically approved, record the selected diameter, taper angle, matching rod model or rod-end drawing or measurements, bit socket or insertion depth, face type, button shape, count and layout, flushing arrangement and controlled drawing revision, and bind them to an approved configuration ID.

Configuration to confirm before technical approval
- Selected diameter and taper angle: 7°, 11°, 12°, other or not sure, with no default.
- Matching rod model, H22 confirmation and a rod-end drawing, measurement or old-part photo.
- Bit socket or insertion depth.
- Face type and button shape, count and layout.
- Central, side or other flushing arrangement.
If the configuration is not known
An identification inquiry may be submitted with “not sure,” the current rod marking, photos and measurements. It must not proceed as a model-specific technical quotation until the missing fields are resolved.
Engineering and quotation output
The technical review must return the selected configuration, controlled drawing revision and one approved configuration ID. A request for a technical proposal does not make any face, button or flushing arrangement a standard supplied option.
Supply and inspection boundary
This inquiry page does not define a standard diameter–taper–socket–face–button–flushing combination. Any inspection method, acceptance criteria, packing scope or record requirement must be expressly accepted in the written quotation or purchase order.
Selection & Technical Guides
Use these guides to prepare measurements and selection questions; the final configuration still requires a controlled quotation drawing.

Compatibility and Required Interfaces
Rock drill and drill steel
H22 drilling system
Rock-drill chuck, H22 rod and bit must form one matched string
Confirm whether the current rod uses an H22 × 108 mm striking interface or another H22 configuration.
Cutting Face and Taper Interface
Matched Taper Seating
The bit socket seats on a drill rod with the same taper angle to transfer percussion and rotation.
Buyer value
Correct matching supports repeatable seating and reduces interface damage caused by mixed taper systems.
Selection condition
Confirm taper angle, socket dimensions and insertion depth by drawing, gauge, sample or clear photos.
Application Scenarios
- Handheld rock drilling
- Quarrying and secondary blasting
- Road, tunneling and foundation work

Frequently Asked Questions
Can 7°, 11° and 12° taper bits be interchanged?
No. The drill rod and bit must use the same taper angle and compatible socket dimensions. Mixing systems can cause poor seating, energy loss and premature interface damage.
What information is needed for an H22 button-bit quotation?
Send diameter, taper angle, existing rod or bit photos, socket dimensions if available, rock type, preferred face/button design, flushing arrangement and quantity.
Matched Tapered Drilling System
A matched H22 tapered drilling system combines the rock drill, H22 rod, 30–40 mm bit, confirmed taper angle, flushing and lubrication.
