Documentary reading of this family

Hilti Hilti P-U is published as an indexable bit family (class Indexable family). This page organizes 5 diameter or configuration variants under slug hilti-p-u. 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 Hilti Hilti P-U: 1.5", "2", "3", "4", "6". Recorded connections: Hilti BI / 5/8"-11 UNC. Distinct working-length values sampled: 17.7. Do not copy one length onto every size.

Variant counts with wet capability: 5. Variant counts with dry capability: 5. 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 Hilti Hilti P-U 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.

Thread / connection

Hilti BI / 5/8"-11 UNC

Never choose a bit from thread alone, capacity, method, material, and RPM also matter.

Check My Drill Compatibility

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.

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.

1.5" → 17.7
2" → 17.7
3" → 17.7
4" → 17.7
6" → 17.7

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”).

How CoringSpec verified this family

Specifications were checked against current manufacturer documentation and official manuals. Marketplace data is used separately for offer availability. Where a specification could not be clearly verified, CoringSpec marks it as unspecified rather than estimating it.
