RevolutionAir™ Needle & Looper Threading
Press a button and RevolutionAir™ blows thread through the loopers — then threads the needles for you. Setup is faster and easier every single time.
8/7/6-Thread Serging & Wave Stitch
Explore 87 stitch combinations with up to 8 threads, including Baby Lock’s exclusive Wave Stitch for eye-catching decorative edges.
From strong seams to statement finishes, Triumph gives you the flexibility to do it all on one machine.
Knee Lift & Variable Speed Control
Keep both hands on your fabric while you raise the presser foot with the hands-free knee lift — perfect for precise serging and curves.
Variable speed control lets you stitch at a pace that feels comfortable, whether you’re flying on long seams or slowing down for detail work.
No-Tension Adjustments & Differential Feed
The Automatic Thread Delivery™ system (no manual tension knobs) feeds the right amount of thread for balanced stitches on different fabrics.
A full-featured differential feed helps tame stretchy knits, prevent wavy seams, or create beautiful gathers and ruffles on purpose.

Why Choose the Baby Lock Triumph?
The Baby Lock Triumph 8-Thread Serger is built for sewists who want the most capable serger in the room without sacrificing ease of use. RevolutionAir™ threading, no-tension ATD, and a huge throat space take the intimidation out of advanced serging.
Whether you're finishing garments, constructing activewear, or adding decorative edges to home décor, Triumph gives you the stitch variety, control, and power to serge with total confidence.
The Baby Lock Triumph model number is BLETS8. Use this when searching for compatible accessories, presser feet, or comparing prices across dealers.
You insert thread into the threading port, press a button, and a burst of air pushes the thread through the patented tubular loopers instantly — no manual looper threading required. A second button then threads the needles automatically. Setup takes seconds and works the same way every time.
The Triumph (BLETS8) is the higher-tier machine. It offers 8-thread serging with 87 stitch combinations including the exclusive Wave Stitch, a 5" throat space (the largest in its class), and full coverstitch capability with RevolutionAir™ needle and looper threading. The Accolade uses ExtraordinAir® threading and is also an excellent advanced serger — the Triumph is the better choice for sewists who want maximum stitch variety and the largest working area.
Yes. RevolutionAir™ removes the biggest frustration new serger users face — manual looper threading — and the Automatic Thread Delivery™ (ATD) system eliminates manual tension adjustments entirely, delivering perfectly balanced stitches on any fabric. When you purchase from Flash Sew & Quilt, you also receive personalized new-owner training at our Naples, Sarasota, or Jupiter locations.
The Triumph handles a wide range of fabrics. Its Advanced Knife Driving system and higher presser foot height (up to 6mm) allow it to cut through thick fabrics like fleece, wool, denim, and multiple layers. The full-featured differential feed tames stretchy knits and activewear, and can also create intentional gathers and ruffles on lightweight fabrics.
The Baby Lock Triumph includes Baby Lock's industry-leading warranty: 25 years limited, 10 years parts, 5 years electrical, and 1 year labor. It is also eligible for the Baby Lock Love of Sewing Membership, which includes annual maintenance from a certified technician, repairs coverage, and unlimited access to Baby Lock's SEWED online classes.
