Flow Fixer 3HDB 3” Heavy Duty Root Cutter Saw Blade for Drain Cleaning

The Pro-Graad FlowFixer 3HDB is a heavy duty saw blade root cutter built for professional drain cleaning on 5/8" and 3/4" cables equipped with standard slotted connectors. It installs directly onto your existing cable — no adapters, no special tools. Alloy steel construction and self-sharpening saw teeth handle roots, grease buildup, and compacted debris that standard spiral cutters leave behind. Bi-directional cutting geometry means the 3HDB cuts on both forward and reverse rotation. When an obstruction catches the blade, reversing the machine frees it instead of driving it deeper — a critical feature on tough root jobs where getting stuck costs time and risks cable damage. The coiled body profile keeps the cutter tracking cleanly through bends, transitions, and vertical stacks. It's designed to operate fully enclosed inside drain lines — sewer mains, downpipes, and underground laterals — where reach and tracking matter as much as cutting power.

• [IN THE BOX]: 1 each Flow Fixer 3HDB 3” Heavy Duty Root Cutter Saw Blade for Drain Cleaning
• [FITS SLOTTED CONNECTOR CABLES — NO ADAPTERS NEEDED]: The 3HDB attaches directly to standard 5/8" and 3/4" drain cables with slotted connectors — the most common connector style on professional drain machines. No adapters, no modifications. Drop it on and run it.
• [ALLOY STEEL CONSTRUCTION WITH SELF-SHARPENING CUTTING EDGES]: Saw teeth are machined from alloy steel and designed to sharpen automatically as they spin against pipe walls and root material. Stays aggressive through extended use without needing to pull the cable and swap attachments mid-job.
• [CUTS FORWARD AND REVERSE — RESISTS GETTING STUCK]: Bi-directional cutting teeth work on both clockwise and counterclockwise rotation. If the blade catches on a root mass or obstruction, reversing pulls it free instead of jamming deeper. Built for the conditions where cheaper cutters fail.
• [ENGINEERED FOR ENCLOSED DRAIN LINES]: Coiled body profile navigates 90-degree bends and tight transitions in vertical stacks, sewer mains, and underground drain lines without gouging pipe walls or joints. Designed to work fully enclosed — not for open gutters or surface drains.
