Best For
The 110-42952 knife is the thread-trimming blade for Juki DDL-8100/8300/8500/8700 series single-needle lockstitch machines, and it’s cross-compatible with Jack F4/F5/F6 machines — the part a factory mechanic reaches for when the auto-trimmer stops cutting cleanly or stops cutting at all.
What It Does
- Cross-compatible with both Juki DDL-8100/8300/8500/8700-series and Jack F4/F5/F6 machines
- Restores clean automatic thread trimming at the end of a stitch cycle
- Direct-fit replacement — no modification needed
Use Cases
Garment factories running Juki DDL or Jack F4–F6 lockstitch lines depend on the auto-trimmer cutting cleanly every cycle; operators keep this knife as a standard maintenance spare since it’s one of the higher-wear parts on the trimmer assembly.
Benefits
A dull or chipped trimmer knife is one of the most common reasons an auto-trim machine leaves long thread tails or stops trimming altogether — it’s a well-documented issue across the Juki DDL-8700 range specifically, and the fix is almost always the knife rather than the whole trimmer solenoid assembly. Replacing it is far cheaper than replacing the trimmer mechanism.

How to Use
First, power down and unplug the machine before accessing the trimmer assembly beneath the throat plate. Next, remove the mounting screw holding the old knife and lift it out. Then, fit the 110-42952 in the same position and secure the mounting screw, checking the blade edge aligns correctly against its mating knife. Finally, hand-cycle the trimmer mechanism to confirm a clean cut before running the machine under power.
FAQ
Buyer Intent
Q: My auto-trimmer leaves long thread tails instead of cutting close – is it the knife?
Usually yes — a dull, chipped, or misaligned trimmer knife is the most common cause of long thread tails or incomplete trims on Juki DDL-8700-series machines and is the first thing worth checking before replacing the whole trimmer solenoid.
Q: Is this a genuine Juki part or a compatible replacement?
This is a compatible replacement built to the 110-42952 specification, cross-compatible with both Juki DDL and Jack F-series machines — not an original Juki-branded part, sold as a lower-cost factory maintenance spare.

Q: Will this fit a Juki DDL-8700-7 specifically?
