CRAFTSMAN String Trimmer Line, 0.065" Spool (CMZST065)

What It Is

This is a 0.065-inch diameter replacement spool for Craftsman string trimmers, designed for light-duty trimming of grass and small weeds. It fits most Craftsman battery-powered and electric trimmers that use a pre-wound spool.

Fitment & Compatibility

• Line diameter: 0.065” (1.65 mm) – only for trimmers that accept this size; thicker lines (0.080”+) will not load.
• Spool type: Pre-wound drop-in spool (not bulk line). Check your trimmer’s head design – if it requires a specific spool shape (e.g., SpeedFeed, Tap-N-Go), this may not fit.
• Model check: Compatible with most Craftsman CM, CMC, and 25cc gas trimmers that use a 0.065” line. Verify your trimmer model number (e.g., CMEST525, CMXGTAMD25SC) against the manufacturer’s compatibility list.
• OEM vs aftermarket: This is a genuine Craftsman part (CMZST065). Aftermarket spools may be cheaper but risk fit issues or jamming.
• Measure before buying: Remove your current spool and compare its diameter and hub shape. Also confirm the line diameter by checking the trimmer’s manual or the old spool label.

Key Things to Know

• Installation: Drop-in design – no winding or cutting needed. Push the spool into the head, thread the line through the eyelets, and snap the cap on. Takes under 2 minutes.
• Quality: Line is durable for light use but can break faster on thick weeds or against hard surfaces (fences, rocks). Expect 20–30 minutes of continuous trimming per spool.
• Gotcha: Not all Craftsman trimmers use this spool. Some require a 0.080” or 0.095” line, or a different spool shape. Check your trimmer’s manual or the old spool’s part number before buying.
• Bump-feed works well: The line advances reliably with a light tap on the ground, but avoid over-tapping – it wastes line.

Should You Buy It

Buy this if you have a Craftsman electric or battery trimmer that takes 0.065” line and want a hassle-free, pre-wound spool that installs in seconds. It’s ideal for weekly lawn maintenance on small to medium yards. Skip it if you need thicker line for heavy brush or if your trimmer uses a different spool design – measure first to avoid a return.
