SCHMETZ Leather Machine Needle Size 18/110 — 3 Pack Wedge-Point Heavy-Duty Needles for Leather

SCHMETZ Leather Machine Needle Size 18/110 (3 Pack) is a set of heavy-duty sewing needles engineered with a wedge point to cleanly penetrate leather and other dense materials without tearing.

This three-pack of SCHMETZ leather machine needles gives hobbyists and professional sewers a reliable, purpose-built option when working with genuine leather, vinyl, coated fabrics, or layered materials. Each needle is sized 18 / 110 — a large diameter needle designed to maintain stitch quality through thick substrates while minimizing skipped stitches. The set is intended for use in compatible home and industrial sewing machines that accept standard system needles; always match your machine's specifications before installation.

How does this needle handle leather and heavy materials?

The wedge (cutting) point of the SCHMETZ leather needle slices through leather fibres instead of forcing them aside, which reduces puckering and keeps stitch formation consistent. Its larger diameter stabilises thread as it passes, improving stitch reliability on tough seams.

• Wedge point design for cleaner piercing of leather and vinyl
• Size 18/110 suited to multi-layer or thick single-layer leather
• Reduced skipped stitches and better stitch formation on heavy fabrics

Will these needles fit my sewing machine?

These SCHMETZ leather needles use the standard needle shank for most domestic and many industrial machines, but machine compatibility varies. Check your machine manual for accepted needle sizes and system type before use to ensure a safe fit and correct needle alignment.

• Standard shank for common machine systems—verify with your manual
• Intended for both heavy domestic and some light industrial machines
• Replace bent or dull needles immediately to avoid damage to material

How should I use and care for a leather machine needle?

Install the needle with the flat shank oriented as your machine requires and use an appropriate heavy-duty thread and oil-leather-compatible presser foot. Change needles regularly when stitching dense materials: a sharp needle ensures consistent results and reduces wear on both fabric and machine.

• Use heavy-duty thread and matching tension settings
• Choose a leather-compatible presser foot and adjust pressure as needed
• Swap needles after visible wear, bending, or every few project hours

What stitch quality can I expect with a size 18/110?

Size 18/110 provides a sturdy needle path that supports thicker threads and maintains stitch integrity across seams. Expect slightly larger stitch holes appropriate for rugged applications like upholstery or leather goods, while still achieving even stitch length when machine settings are adjusted properly.

• Larger needle hole suitable for heavy-duty threads and leathers
• Consistent stitch length with appropriate machine tensioning
• Best for functional seams and decorative topstitching on heavy materials

Who is this for: This 3-pack of SCHMETZ Leather Machine Needles Size 18/110 is aimed at leatherworkers, upholstery makers, shoe and bag crafters, and home sewers tackling heavy or layered materials who need a reliable cutting-point needle. It suits users who want predictable stitch results on dense substrates and who follow their machine’s needle and thread recommendations.
