Singer Heavy Duty 4511 Sage: Metal Frame Strength for Everyday Sewing
The Singer Heavy Duty 4511 Next Evolution is a mechanical sewing machine with a full metal interior frame, a stainless steel bedplate, and strong piercing power for denim and thicker layers. It has 11 built-in stitches, a 4-step buttonhole, and more than 6 inches of space to the right of the needle. Singer finishes this version in a vintage-inspired Sage.

Strong Piercing Power for Denim
A DC motor drives the needle through denim and thicker layers. The full metal interior frame and stainless steel bedplate support steady stitching, and adjustable presser foot pressure sets how firmly the foot holds the fabric.

Four-Step Buttonhole
Sew a 4-step buttonhole with the machine guiding you through each step. The result is a well-balanced buttonhole for garments and home projects. A buttonhole foot is included in the box, so you can sew buttonholes as soon as the machine is set up.

Top Drop-In Bobbin
The jam-resistant top drop-in bobbin is easy to wind and insert. A transparent bobbin and cover plate show how much thread is left, so you can change it before a seam runs out.

More Than 6 Inches of Sewing Space
With more than 6 inches to the right of the needle, quilts, home decor pieces, and bulky seams have extra room to pass through. Set the needle to the left, center, or right position to place the stitch line as you guide a larger piece through.

11 Stitches with Adjustable Length and Width
Choose from 11 built-in stitches, utility and decorative, for everyday sewing, mending, and creative projects. Stitch width reaches a maximum of 6 mm and stitch length a maximum of 4 mm.
Free Arm and Drop Feed
The free arm fits cuffs, hems, and other small areas. Drop feed lowers the feed teeth for free-motion monogramming, free-motion quilting, button sewing, darning, or thread painting, then re-engages for regular sewing.
4 Presser Feet and Accessories Included
The all-purpose, buttonhole, zipper, and blind hem feet come in the box with a pack of 3 needles, four Class 15 transparent bobbins, an edge/quilting guide, and a seam ripper with lint brush.
