Documentary reading of this family
Weka WEKA Standard Wet is published as an indexable bit family (class Indexable family). This page organizes 4 diameter or configuration variants under slug weka-diamond-core-bits-wet. A family name is not a specification. Diameter-specific working length, interface, method, reinforcement, and any published speed limit stay on the exact variant.
Recorded diameters in Weka WEKA Standard Wet: 2", "3", "4", "6". Recorded connections: 1-1/4"-7 UNC Female. Distinct working-length values sampled: 18. Do not copy one length onto every size.
Variant counts with wet capability: 4. Variant counts with dry capability: 0. Reinforcement labels sampled: MEDIUM. Unspecified rebar ratings are not treated as heavy reinforcement approval. A general concrete family description does not invent rebar capacity for a specific variant that lacks that field.
No variant-level maximum RPM is recorded for Weka WEKA Standard Wet in the current sample. That gap is not filled from a generic diameter chart or from another family.
Family fit-for text: not provided Use the diameter selector and the Core Bit Finder with a known drill so capacity, method, depth, and one documented adapter path can be tested. Variant SKU URLs remain database records and are not auto-scheduled as indexable pages.

Compare Wet vs Dry Core Drilling
Thread / connection
- 1-1/4"-7 UNC Female
Never choose a bit from thread alone, capacity, method, material, and RPM also matter.
Adapter requirement
Same thread is not complete compatibility. Use the Core Bit Finder with a selected drill, adapter-required paths show the documented adapter when present. Maximum one adapter by default. See the adapters hub for documented connection accessories.
Compatible drills
Open the Core Bit Finder with this diameter to evaluate drills live.
RPM by diameter
| Diameter | Max RPM |

| 3" | Unknown / Not specified by manufacturer |
| 4" | Unknown / Not specified by manufacturer |
| 6" | Unknown / Not specified by manufacturer |
Manufacturer/OEM RPM on variant records is distinct from calculator-derived guidance. Never treat calculated RPM as a manufacturer specification. Missing RPM = RPM data incomplete.
Reinforcement suitability
Levels present in this family: Manufacturer Specified.
“Concrete compatible” does not necessarily mean appropriate for substantial reinforcement. Claims are variant-scoped.
Working depth
Bit working length is not the same as machine capacity, stand travel, or extension use. A 14" bit does not guarantee a 14" hole in every setup.
- 2" → 18
- 3" → 18
- 4" → 18
- 6" → 18
Limitations
- Family marketing claims are never treated as universal specs for every diameter.
- Amazon ASINs are marketplace offers, manufacturer SKU is the canonical identity.
Ownership & Service
OEM bit retipping / segment replacement: UNKNOWN for this family (not “unavailable”).
