Ridgid 98040 Spiral Saw Tooth Cutter

The Ridgid 98040 Spiral Saw Tooth Cutter is a 4-inch steel accessory built for professional drain cleaning. It mounts on K-1500, K-1500G and K-1500SP sectional machines using a 1-1/4 inch female coupling. Plumbers clearing 4-inch minimum diameter lines will find it compatible with part numbers 23712 and 23717.

Sharktooth geometry under sustained cutting

The Sharktooth head engages pipe walls continuously while the sectional cable rotates under load. Steel teeth maintain their profile through repeated contact with roots, scale and debris without the rapid dulling seen in lighter alloys. The spiral pattern evacuates cuttings as the cutter advances, preventing binding during long runs.

Steel construction manages heat and vibration

Solid steel body mass absorbs the torsional spikes that occur when the cutter hits a heavy obstruction. Heat generated by friction dissipates through the full cross-section rather than concentrating at the teeth. The rigid coupling transmits torque cleanly, reducing chatter that can fatigue the cable over extended jobs.

Questions about this item

How does the steel sharktooth cutter handle heat during extended drain-cleaning runs?

The solid steel body dissipates cutting heat naturally; no active cooling is required and the material resists warping under continuous use.

Which Ridgid sectional machines must I already own for the 98040 cutter to connect?

It fits K-1500, K-1500G and K-1500SP machines using the 1 1/4 in female coupling on 23712 or 23717 cables.

Will this 4 in sharktooth cutter work on the older K-1500A and K-1500B cable drums I keep in the truck?

Yes — the cutter is listed for both 23712 and 23717 cable assemblies, so it mounts directly on those legacy drums.
