Compatibility and Required Interfaces
Rock Drill
Rock drill with verified H22 × 108 mm chuck and striking interface
Shank cross section, shank length, collar and retention must match the delivered drill
YT28 and YT29A model families commonly use H22 × 108 mm interfaces, but the delivered chuck and supplier drawing must still be checked.
Tapered Drill Bit
Matching 11° tapered drill bit
Taper angle and socket must match exactly
Select bit diameter, button or chisel design and flushing arrangement according to hole size, rock condition and drilling system.
Tapered Drill-String Design
Matched 11° Taper Interface
The tapered end seats into a drill bit with the same taper angle to transfer impact and rotation through the rod-to-bit connection.
Buyer value
Creates a replaceable tapered drill-string interface for hand-held and air-leg drilling when the rod, bit and rock drill are correctly matched.
Selection condition
The rod and bit must both use the same 11° taper. Confirm the socket and taper using a drawing, gauge or physical sample.
Hollow Flushing Path and Collared Interface
The hollow rod provides a central passage for flushing while the collar locates the rod at the rock-drill interface.
Buyer value
Supports removal of cuttings and stable positioning in a complete tapered drilling system.
Selection condition
Confirm flushing medium, bore, rod length, collar position, straightness and rock-drill interface for the selected drilling system.
Application Scenarios
Hand-held pneumatic rock drills
Air-leg rock drills

Frequently Asked Questions
How should I choose the drill-rod length?
Provide the target hole depth, drilling direction, working space, preferred rod-handling method and current rod length. Effective length should be measured consistently from the collar to the bit end and confirmed on the quotation or drawing.
Can an 11° rod be used with a 7° or 12° bit?
No. The rod and bit taper angles must match exactly. Mixing taper angles can cause poor seating, energy loss, damage to the socket or taper and premature separation.
Is this rod compatible with YT28 or YT29A rock drills?
It can be selected for a YT28 or YT29A only when the delivered rock drill uses the required H22 × 108 mm striking interface and the collar and retention arrangement match. Confirm the chuck drawing, current rod or physical sample before order.
Matched Tapered Drilling System
A complete tapered drilling system can include the rock drill, H22 × 108 mm tapered rod in the required length, a matching 11° bit, lubricator, hoses, flushing supply and recommended wear parts. Every interface must be confirmed before order.
