Singer Heavy Duty 4523: Metal-Frame Sewing in Beige
The Singer Heavy Duty 4523 Next Evolution is a dial-controlled sewing machine with 23 built-in stitches, a full metal interior frame and a stainless steel bedplate. It sews lightweight, medium and heavier fabrics, including stretch fabrics.
Speed control, an integrated needle threader and a one-step buttonhole are built in, and Singer's limited warranty covers the metal frame for the lifetime of the machine with free replacement parts and labor (shipping at your cost).

Strong Piercing Power and a Metal Frame
Strong piercing power and adjustable presser foot pressure help keep stitching smooth and consistent across fabric weights. The full metal interior frame is covered for the lifetime of the machine with free replacement parts and labor (shipping at your cost), and a new DC motor drives the machine.

23 Stitches for Everyday Sewing
Choose from 23 built-in stitches: utility, stretch and decorative. Maximum stitch width is 6 mm and maximum stitch length is 4 mm. The one-step buttonhole sews a consistent buttonhole sized to your button.
Speed Control
Set the machine's maximum sewing speed to suit the job. Slower settings give more control on corners, curves, small projects and techniques where precision matters. The top speed is 1,000 stitches per minute.

Rubberized Dial Grips
Both the stitch selector dial and the stitch length dial have textured rubberized grips for added comfort and control. Picking a stitch or changing the length takes a simple turn of the dial, so adjustments are easy to make between seams.

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 see it before a seam runs out.

Integrated Needle Threader
The integrated needle threader makes it simple to thread the eye of the needle. That saves time and gets you sewing sooner, whether you are setting up for the first time or rethreading in the middle of a project.

Large Sewing Space
6+ inches of space to the right of the needle gives larger projects more room. That extra space suits work like the pieced quilt top pictured, where the bulk of the project sits beside the needle as you sew. The free arm reaches cuffs, hems and sleeves.

Stainless Steel Bedplate
The stainless steel bedplate sits on both sides of the needle plate, as the image shows with the presser foot attached. It is part of the machine's metal build, alongside the full metal interior frame. The feed system is drop feed capable.
Presser Feet and Accessories Included
Four presser feet are included: all purpose, buttonhole, zipper and blind hem. The box also holds a pack of 3 needles, 4 Class 15 transparent bobbins, an edge/quilting guide, a seam ripper with lint brush, and a needle plate screwdriver.
