Designed Specifically for Asphalt and Abrasive Concrete

Unlike standard concrete bits, ROC Abrasives Wet Core Bits are purpose-built for asphalt and other highly abrasive materials. Asphalt’s soft but gritty texture can rapidly wear down standard bits; that’s why these core bits use a softer bond matrix that allows diamonds to stay exposed for longer, maintaining cutting speed and preventing premature glazing.

For abrasive concrete—a mix often containing high sand or lightweight aggregates—the same engineering principles apply. The unique bonding system keeps the bit sharp even when cutting through highly erosive materials, resulting in cleaner holes, faster drilling, and extended tool life.

Key Applications Include:

• Core drilling for road repair and resurfacing.

• Cutting utility access holes for pipes, cables, and conduits.

• Creating expansion joints and drainage holes in asphalt.

• Drilling in abrasive concrete slabs, bridge decks, or pavements.

• Use in civil engineering and municipal construction projects.

Whether you’re cutting through a freshly paved road or an aged concrete surface, the ROC Abrasives Wet Core Bit ensures consistent penetration without overheating or chipping.

Premium Diamond Segment Technology

At the heart of every ROC Abrasives core bit is its precision-engineered diamond segment. The 8mm (.315”) segment height offers a perfect balance between speed, longevity, and stability—giving you extended cutting life while maintaining high drilling performance.

Segment Advantages:

• Optimized for Abrasive Materials: The bond composition ensures continuous exposure of diamonds, preventing loss of cutting efficiency.

• Laser-Welded Construction: Each segment is laser-welded to the barrel, guaranteeing strength and durability under heavy load conditions.

• Self-Sharpening Design: As the bit wears, new diamonds are exposed, maintaining cutting speed throughout its lifespan.

• Precision Cut Geometry: The segment shape provides efficient slurry evacuation and cooling, minimizing friction and vibration.

This advanced diamond technology ensures that ROC Abrasives Wet Core Bits maintain consistent performance across long drilling sessions, even in highly abrasive environments.

Built with a 14-Inch Long Steel Barrel

The 14" long barrel offers superior reach and cutting depth for both surface and deep coring applications. Constructed from heavy-duty heat-treated steel, each barrel is designed for maximum rigidity and vibration control.

Features of the 14" Barrel:

• Deep Coring Capacity: Allows for extended drilling depth in thick asphalt or layered concrete.

• Stability Under Pressure: Reduces wobble and deflection, ensuring straight, accurate holes.

• Corrosion-Resistant Finish: Extends barrel life in wet environments.

• Universal Thread Compatibility: Works seamlessly with standard 1-1/4"-7 UNC core drill arbors, ensuring compatibility with most core drilling rigs.

Whether you’re working with a handheld core drill or a rig-mounted system, the ROC Abrasives 14-inch barrel delivers the strength and precision required for professional-grade results.

Water-Assisted Wet Drilling Technology

Wet drilling is essential when working with asphalt and abrasive concrete. The ROC Abrasives Wet Core Bit utilizes water not only to cool the blade but also to flush away debris and prevent heat buildup, which can cause glazing and slow down the drilling process.

Benefits of Wet Core Drilling:

• Reduces Friction and Heat: Keeps the segment cool to preserve the diamond bond.

• Extends Tool Life: Prevents premature wear caused by high temperatures.

• Improves Drilling Speed: Allows for faster penetration without burning or binding.

• Minimizes Dust: Creates a cleaner, safer working environment by suppressing airborne particles.

• Produces Clean, Smooth Holes: Reduces chipping and edge spalling around the drilled area.

By combining wet core drilling efficiency with ROC’s diamond segment engineering, contractors can achieve faster results, longer runtime, and cleaner finishes.

Optimal Performance and Longevity

Proper technique and care can dramatically extend the lifespan and performance of your ROC Abrasives Wet Core Bit.

Tips for Best Results:

• Always use adequate water flow to keep the bit cool and prevent glazing.

• Begin drilling at a slow speed, allowing the bit to seat before applying full pressure.

• Avoid dry use—dry drilling on asphalt can lead to overheating and rapid wear.

• Use the right bond for the material—the 30P or soft bond line from ROC is designed specifically for asphalt and abrasive concrete.

• Clean after each use to prevent slurry buildup inside the barrel.

By following these simple practices, contractors can maximize both cutting efficiency and tool life, ensuring consistent performance from start to finish.
