ROUND POINT WITH SMALL TRIANGULAR TIP NEEDLES

Groz Beckert 135x17 SD Industrial Sewing Machine Needles – TRI TIP

The Groz Beckert 135x17 SD is a high-performance industrial sewing machine needle featuring the SD1 point style, also known as TRI TIP – a round point with a small triangular incision. This specialised needle cuts approximately 10% of the stitch hole while displacing 90% with its conical tip, producing a straight seam with a clean, tidy appearance. The SD1 point is gentler than standard cutting points, making it ideal for delicate and coated materials.

This needle is chrome-coated for increased wear resistance, ensuring durability and smoother operation during high-volume production. It is also highly effective in multi-directional and programmable sewing, delivering consistent stitch appearance across all directions.
