KAKO Sawtooth 175 Trimmer Line .175-inch — 468 ft (5 lb) Dual-Core Serrated Heavy-Duty for Tough Weeds

KAKO Sawtooth 175 is a heavy‑duty .175‑inch serrated trimmer line engineered to cut thicker grass and stubborn weeds faster while lasting longer than standard round lines.

Whether you're a homeowner with overgrown yard edges or a pro landscaper tackling dense vegetation, the KAKO Sawtooth 175 offers a balance of durability and cutting performance. Made from reinforced nylon and shaped with a serrated (sawtooth) profile, this .175‑inch line reduces engine drag and vibration while keeping a sharper edge through extended use. The spool contains 468 feet (5 lb) of dual‑core string to refill multiple trimmer heads or to keep a single unit stocked for frequent jobs.

How does the sawtooth shape improve cutting performance?

The serrated profile slices rather than just bruises plant stems, so it severs tougher weeds and thicker grass more efficiently. That results in cleaner cuts, less string wear per job, and reduced time spent re‑trimming.

• Sawtooth edge maintains a sharper cutting surface compared with round lines.
• Dual‑core construction increases impact resistance and reduces breakage.
• Less motor drag and vibration—improves fuel or battery efficiency.

Will this .175 line fit my trimmer or wheeled mower?

Yes—the KAKO Sawtooth 175 is compatible with most heavy‑duty walk‑behind trimmer mowers and handheld units that accept .175‑inch (4.45 mm) line. It works with major brands and most commercial heads, but always check your machine’s manual for diameter limits.

• Fits Echo, Husqvarna, Ryobi, Redmax, Cub Cadet, and more.
• Suitable for both standard bump heads and many fixed‑spool configurations.
• Compatible with commercial walk‑behind wheeled trimmers using .175 line.

How long will a 468‑foot spool last for routine landscaping?

Longevity depends on vegetation density and frequency of use, but the 5‑lb spool offers multiple refill sessions for homeowners and several days of work for pros. The heavier gauge and sawtooth profile lower consumption compared with thinner round lines because less line is wasted from breakage or rapid wear.

• 468 ft provides enough line for many refills of a typical bump head.
• Durable nylon construction resists snapping under heavy use.
• Ideal for extended projects where downtime for refilling is a concern.

What practical benefits will I notice on the job?

Expect faster, cleaner trimming with reduced noise and vibration versus comparable thick round lines. The string’s toughness means fewer interruptions to replace broken segments and steadier engine performance under load.

• Improved cutting speed through dense brush and tall weeds.
• Lower vibration for more comfortable handheld use and reduced wear on trimmer components.
• Commercial‑grade length and weight minimize resupply trips.

Who is this for: KAKO Sawtooth 175 is designed for homeowners who want a longer‑lasting line for heavy gardens, property managers maintaining multiple lawns, and landscape professionals who need a rugged, high‑efficiency string for commercial trimming. If your work includes thick grass, briars, or frequent edging, this .175 sawtooth line delivers a cost‑effective mix of durability and cutting power without the increased drag of oversized cord.
