CIR90 DTH Button Bit
Model:CIR90
Selected configuration:Configuration to be confirmed
Selected reference:Configuration required
CIR90 low-pressure DTH button bit for a confirmed CIR90 hammer/shank interface. Exact diameter, face, button and flushing geometry are quotation-controlled to prevent model or configuration mixing.
- CIR90 interface-family identity is explicitly controlled
- Order-specific geometry is confirmed before release instead of inferred
- Inspection can be aligned to the approved bit specification

Frequently Asked Questions
Can I order a DTH bit by hole diameter alone?
No. Similar nominal diameters can exist across different interface families. Confirm the matched hammer/shank interface and exact bit geometry together.
Are CIR-family DTH bits automatically interchangeable?
No. Confirm the actual mating profile, critical dimensions and approved configuration before substitution or repeat ordering.
What information should I send for a DTH bit quotation?
Send the matched hammer model, target hole diameter, current bit photos or drawing if available, face/button preference, rock condition, quantity and destination.
Are the hammer and drill pipe included with the bit?
Not unless the written quotation explicitly lists them. System components should be requested and itemized separately in the RFQ.
