Core Drill Bits
Professional-Grade Pipe Cutting Solutions
Joints Couplings’ diamond core bits are built for relentless durability in underground sewer pipe cutting, delivering unmatched resilience in open trenches, below ground, or above ground. Crafted with premium diamond-impregnated segments, these bits withstand abrasive reinforced concrete, clay, PVC, and ductile iron pipes, delivering consistent performance. Whether cutting in open trenches, below ground, or above ground, they resist wear from heavy rebar and tough aggregates, ensuring long-lasting sharpness and structural integrity. Rugged design minimizes downtime and replacement costs, making them the go-to choice for contractors installing lateral pipe connections in demanding sewer and storm pipe projects.
Features
- Super-Tough Diamond Segments: Rock-solid diamond segments, fused with laser-strong bonds, blast through sewer pipe coring with unbeatable toughness.
- High-Strength Steel Core: Engineered with a rigid steel barrel, resists twisting forces, carving spot-on 360-degree circular cuts on round pipe exteriors.
- Smart-Cut Segment Slots: Precision-shaped slots whip up tough cutting grit, blazing through concrete and clay sewer pipes for flawless Tap-N-Tee fittings.
- Pinpoint Hole Sizing: Ultra-accurate crafting locks in perfect hole sizes, nailing seamless sewer pipe fittings every time.
- Smooth-Spinning Balance: Evenly spaced segments cut vibrations, delivering dead-on, clean holes on curved pipe surfaces.
