Echo 330095071 Black Diamond 1 Lb 253' Donut .095" Gauge Twisted String Trimmer

What It Is

This is a 1-pound donut spool of Echo’s Black Diamond twisted .095″ trimmer line, designed for heavy-duty trimming on commercial-grade gas trimmers and high-torque electric models. The twisted shape and diamond coating help it cut through thick weeds and light brush without shattering.

Fitment & Compatibility

• Line gauge: .095″ (2.4mm) – fits trimmer heads that accept this thickness. Check your head’s max line diameter; .095″ is common on Echo SRM-225, SRM-2620, PAS-225, and many Stihl, Husqvarna, and Ryobi heads.
• Spool type: Pre-wound “donut” – you must manually wind it onto your trimmer head. Not a drop-in replacement spool.
• OEM vs aftermarket: Echo OEM part #330095071. Works in any brand head that uses .095″ line, but best performance in Echo heads.
• Length: 253 feet total – enough for several reloads on a standard head.

Key Things to Know

• Cutting performance: The twisted diamond profile is noticeably more aggressive than standard round line. It’s louder and wears faster on pavement but excels in tall grass and briars.
• Installation difficulty: Easy – just wind evenly onto your spool. No special tools needed. Avoid overlapping or bunching to prevent jamming.
• Common gotcha: This line is stiffer than standard .095″. Some auto-feed heads (e.g., SpeedFeed) may require an initial bump to break in the twist. If your head is finicky, try soaking the spool in warm water for 10 minutes to soften it.
• Durability: Lasts about 20-30% longer than standard round .095″ line in heavy brush, but chips faster on concrete edging.

Should You Buy It

Buy this if you’re tackling thick weeds, blackberries, or saplings with a medium-to-heavy-duty trimmer (35cc+ gas or 40V+ electric) and want longer run time between line changes. Skip it if you only trim grass along sidewalks – standard round line is cheaper and quieter for light work.
