Precision-Ground Point for Cleaner Hems

A precision-ground curved point sets this needle apart from standard blind stitch needles. It nicks the fabric instead of fully piercing it, so the stitch stays hidden on the outside. This cuts down skipped stitches and keeps the hem line smooth. The sharper edge also holds up longer between changes, reducing machine downtime.

How To Use

First, match the needle size to your fabric — sizes 9 to 12 for light fabric, 14 for medium-weight suiting. Next, loosen the needle clamp screw and remove the old needle. Then, insert the new needle with the curved point facing the direction marked on the machine. After that, tighten the clamp and turn the handwheel by hand to confirm it drops clear of the hook. Finally, test-stitch on scrap fabric before starting production.

FAQ

What size Turpai machine needle should I use?

Size depends on fabric weight. Groz-Beckert lists this needle in Nm 65/9, 75/11, 80/12 and 90/14. Use the finer sizes (9 to 12) for light fabric and size 14 (Nm 90) for medium-weight cotton and wool suiting. These are the official blind stitch needle sizes for turpai machines; Groz-Beckert recommends this needle for woven fabrics such as trousers and suits.

Will this needle fit my blind stitch machine brand?

The LWX6T system fits most turpai and blind stitch machines, including Jack, Typical, and Daisen. If your machine uses a different system, check the number on your old needle before ordering.

How often should I replace the needle?

Replace after roughly 8 hours of continuous stitching, or sooner if you see skipped stitches, fabric pulls, or a bent tip. Synthetic fabric wears the point down faster than natural fibers.

Why do stitches still show on the outside after hemming?

This usually means the needle depth or size is wrong for the fabric. Check the curved point direction, adjust the machine’s bite width, and switch to a finer size 11 or 12 needle for delicate material.

Is “sui needle” the same thing as this Turpai machine needle?

Yes — “sui” is the Hindi/Urdu word for needle, so “sui needle” is simply how many buyers in India search for any sewing machine needle (also typed as machine ki sui or blind hemmer needles), including this Turpai/blind stitch needle. If you’re looking for a needle for a straight-stitch or overlock machine instead, see our full sewing machine needles range.

How much does this sui needle cost?

This Groz Beckert Turpai machine sui needle starts at ₹500, with Cash on Delivery available pan-India. Note this is the needle only: turpai machine price for a complete blind stitch machine is far higher, with IndiaMART dealer listings running roughly ₹30,000 to ₹53,000.
