P4™ Turbo Pointed Wet Core Bit for Concrete

P4 Turbo Pointed Wet Core Bit for Concrete — Faster, Cooler Cutting with Extended Diamond Life

The Pearl Abrasive P4™ Turbo Pointed Wet Core Bit (Item HB0100PT) is a 1-inch diameter diamond core bit engineered specifically for wet drilling in concrete and masonry. Designed for contractors and trades professionals who demand consistent performance in demanding applications, this bit features a pointed turbo segment geometry that accelerates cutting speed while reducing heat buildup. The diamond bond is formulated for an extra-long working life, making it a cost-effective choice for high-volume drilling operations in concrete, reinforced concrete, brick, block, masonry, and stone.

Technical Specifications

The P4 Turbo Pointed design sets this bit apart from standard flat-segment core bits by combining pointed segment edges with a turbo profile, delivering faster penetration rates and cooler operation during extended wet drilling sessions. The back screw feature on 1″ to 6¼″ diameter bits simplifies core removal and allows users to attach extension barrels to increase drilling depth without changing setups. A wide range of optional adapters and extensions further expands versatility across job site configurations.

Key Features & Benefits

Pointed Turbo Segment Design

The pointed edges combined with the turbo segment geometry concentrate cutting force at the leading edge, enabling faster penetration into concrete and masonry. This design also promotes better water flow through the cut, keeping the bit cooler and reducing the risk of segment glazing during continuous use.

Extra-Long Diamond Bond Life

The diamond bond is specifically engineered for extended working life, reducing the frequency of bit replacement on long drilling projects. For contractors running multiple holes per day, this translates directly into lower tooling costs and less downtime swapping bits.

Back Screw Core Removal Feature

The integrated back screw feature (available on 1″ to 6¼″ diameter bits) allows users to quickly and easily remove the core slug from the barrel without improvised tools or excessive effort. This feature also enables the attachment of extension barrels, expanding the effective drilling depth beyond the standard barrel length.

Wide Range of Optional Adapters and Extensions

Compatibility with a broad selection of Pearl adapters and extension barrels means this bit can be configured for a variety of drill setups and access conditions. This flexibility reduces the need to carry multiple specialized bits on the job site.

5/8″-11 Arbor Bore

The standard 5/8″-11 threaded arbor bore ensures compatibility with the most common wet core drill motors used in the construction trades. No adapter is required for most standard setups, allowing for fast bit changes in the field.

Common Applications

Concrete Drilling

Designed for wet drilling through standard and reinforced concrete slabs, walls, and foundations where clean, precise holes are required.

Masonry and Block Drilling

Effective for drilling through brick, block, and general masonry construction, including CMU walls and similar structures.

Stone Drilling

Suitable for wet core drilling in natural and engineered stone applications where a clean bore is needed.

Extended-Depth Drilling with Extension Barrels

When paired with compatible extension barrels, the P4™ can drill beyond the standard barrel depth, making it suitable for thick walls or deep penetrations that exceed the standard 16″ height.

Frequently Asked Questions

Q: Is this core bit designed for wet or dry drilling?
A: The P4™ Turbo Pointed Core Bit is designed specifically for wet drilling. Water delivery is required during use to cool the bit and control dust.

Q: What drill thread does this bit accept?
A: This bit has a 5/8″-11 arbor bore, which is the standard thread for most wet core drill motors used in the construction industry.

Q: Can the drilling depth be extended beyond the standard barrel length?
A: Yes. The back screw feature on this 1″ bit allows users to attach compatible extension barrels to increase drilling depth beyond the standard 16″ barrel height.

Q: What materials can this bit drill through?
A: The P4™ is rated for concrete, reinforced concrete, brick, block, masonry, and stone.

Q: What makes the turbo pointed segment design beneficial?
A: The pointed edges and turbo segment geometry promote faster cutting action and cooler operation compared to standard flat-segment designs, helping to extend bit life and improve productivity on the job site.
