Effortless Heavy-Duty Sewing – Thanks to a powerful motor

Powerful motor supplies steady drive so the needle penetrates thick fabrics and stacked seams without frequent stalls. High torque helps maintain stitch rhythm when working through denim and layered materials.

Sewing through heavy denim, canvas or multiple layers becomes manageable, reducing the need to feed fabric manually or switch to hand-sewing.

Versatile Stitching Options – With 32 built-in stitches

Thirty-two selectable stitches cover essential utility and decorative patterns, allowing basic tailoring and repair tasks alongside simple embellishment. Stitch selection gives flexibility for different seam types and fabric behaviours.

Choose from a wide set of stitches for hemming, mending and decorative touches without needing extra attachments.

Neat Finishes and Faster Work – With free arm and high speed

Free arm exposes a narrower sewing bed for working on cuffs, sleeves and other tubular items, while high-speed operation reduces time per seam on longer projects. Both features combine to speed up common workshop tasks.

Easier finishing of small cylinders like sleeves and trouser legs, and quicker progress on larger repair or upcycling jobs.
