Stitch Features: How Thick Can it Stitch?

Singer’s 4423 heavy-duty sewing machine features 23 built-in stitches. You get six basic stitch designs, four stretch, 12 decorative, and one buttonhole stitch. The included stitches will allow you to sew clothes, embroidery, crafts, or home decorations with ease. 

The stitches can be adjusted, too, allowing you to tailor the sewing machine to your needs. There is a stitch width dial that you can turn to adjust the width through six different settings. You can adjust it from zero to 6mm, offering plenty of flexibility and customization.

You can adjust the length of the stitch, too, with the stitch length dial. The dial features four settings ranging from 0.5 to 4mm. These adjustments offer the user to be as creative as they desire with the machine. The adjustable features are particularly great for those wanting to create unique styles such as zig-zag stitches. 

The heavy-duty sewing machine can stitch through thick materials such as denim, leather, canvas, and corduroy. Customers have been able to stitch through these materials with ease. They were able to use the machine to stitch patches onto jackets, attaching multiple materials.  

Some customers reported issues when attempting to sew with heavy felt or multiple layers of canvas. The problem was not widely reported, and for domestic or small business use, we are sure that this sewing machine will be perfect for you!

Singers 4423 isn’t just great for those thicker materials, though. It will stitch through delicate fabrics such as silk, satin, rayon, and lycra. When sewing a range of fabrics, you will need to swap the needle for a thicker or thinner needle. There will be a set of standard needles included that you can choose from to do this. 


Now that we have covered the stitching and materials, the sewing machine is suitable for, let’s look at some of the Singer 4423 heavy-duty sewing machine features.


Singer’s 4423 heavy-duty sewing machine has an impressive stitch speed of 1,100 stitches per minute. This is an excellent speed for domestic sewing or work for a small business. Customers praised the speed of the sewing machine. 

The heavy-duty sewing machine features a stronger motor that is 60% stronger and faster than previously used motors in Singer’s machines. It works to deliver faster stitches, as well as greater piercing power. The added power is excellent for piercing thicker materials such as leather or denim. 

Needle positioning

You get three needle positions on the Singer 4423 that allows you to tailor the machine to your current needs. The range of positions is excellent for zippers, topstitching, or cording. The needle position is easy to change, allowing you to quickly and easily get on with your sewing. 

Talk Foot Pedals to Me

The included foot pedal is straightforward to use. It is extremely sensitive; you won’t need much pressure at all to get high-speed stitching! This was not to every customer’s style, especially when they wanted to stitch slowly and carefully. 

They found that placing their foot entirely on the foot pedal was the best way to ensure complete control of it. Do not let this put you off, though! After a few uses, you will be used to the increased sensitivity of the foot pedal and stitch with ease. 

Details on the Presser Foot

For sewing machine novices, the presser foot is an attachment on your sewing machine that holds the fabric flat as it is fed through the machine and stitched. It will look like a pair of skis sitting by your needle. Singer 4423 features an extra high presser foot lift that allows thicker fabrics to slide in with ease. 

Ideally, the presser foot should be high enough to allow for a range of materials to be fitted underneath. Singer 4423 features a pre-set pressure foot. You won’t need to adjust the foot for different fabric weights. This feature makes it an excellent option for beginners; you don’t need to worry; simply select your material and go! 

There will be a small handle or lever that allows you to raise the foot to use the presser foot. Slide your material underneath, and then lower the foot into place so that the fabric is securely kept in place. 

You get four different feet with your Singer 4423. An all-purpose foot, zipper foot, buttonhole foot, and a button sewing foot will allow you to complete sewing tasks straight away. The buttonhole foot, in particular, is a great feature, although we would recommend that beginners practice on a sample beforehand! With one step, you will have a buttonhole in your fabric, and the included manual has detailed instructions to do this problem-free. 

It is worth noting that the buttonhole feature has no automatic stop. You will need to take a little care to avoid balling thread at the end of your buttonhole. After a few uses, this will become second nature, though! 

Now, what about some extras? You can purchase nine other feet for those who want to use the Singer 4423 for a business or more intricate work. These are widely available online for you to purchase, but be mindful that this adds cost to your sewing machine. 

You can choose from the following feet: 

  • even feed
  • darning/embroidery 
  • gathering
  • quilting/straight stretch 
  • blind hem 
  • satin stitch 
  • overcasting 
  • hemmer 
  • cording 

Thanks to these additional feet, your sewing machine will have endless possibilities! What’s more, you won’t need to worry about changing the foot. Singer’s pedal feet simply snap on and off to provide a quick change over. 

Free arm

Singer 4423 features a free arm that offers you the flexibility to access hems, cuffs, collars, and other narrow sized, hard-to-reach areas with ease. The feature is excellent for those who want to explore their creativity and create or repair clothing. 

A free arm is an excellent feature to have on a sewing machine for beginners and advanced sewers alike! You will never need to worry about getting the angle right for your sewing project. 

Reverse! Reverse! 

The automatic reverse is another excellent feature that the Singer 4423 has. It allows you to reinforce your stitches and provide added strength to your work. The automatic reverse is easy to use and will allow beginners and advanced sewers alike to work quickly and easily. 

Easy to Use?

Singer’s sewing machine is excellent for beginners and advanced sewers alike. There are many video tutorials online that you can watch for tips and detailed instructions on using the 4423 sewing machine. 

Singer 4423 features a range of features that make the sewing machine easy to use. The automatic needle threader is one of these. After threading your sewing machine, the function allows you to thread the needle’s eye with ease. It removes eyestrain and the frustration that come with needle threading! 

There is also an LED light built-in which illuminates your sewing area. The light will provide excellent brightness for all your sewing needs. You won’t even need to turn your light on in your room to complete your work! 

Another great feature is the drop-in bobbin. The bobbin is easy to install and rethread. You can see the bobbin, too, thanks to its clear cover case, allowing you to monitor the thread and see when it needs replacing—no more surprisingly running out of thread for you! 

The machine also features a handle at the top of the machine, making it easy to transport it should you need to. You won’t need to worry about it being heavy either, as the entire machine weighs 14.5 pounds! 

Noise levels

Any sewing machine will make noise, as we are sure you know. Heavy-duty sewing machines can often be loud machines; they often need to work hard to pierce the needle through thicker fabrics. 

Thankfully, you shouldn’t receive any noise complaints with Singer 4423! Customers did not complain about the noise levels, and when used in the daytime, you should not notice too much noise. On a happy note, heavy duty machines generally provide a low-vibration environment so this machine could be quieter than your old one if the last one shook a lot.


Singer’s sewing machines are known for their incredible strength and durability. These machines are designed to last, and the 4423 is no different! It features a heavy-duty metal interior frame and stainless steel bed frame that provide incredible durability. 

Added Extras

Not only do you get the sewing machine, but Singer’s 4423 heavy-duty sewing machine also comes with a whole host of added extras! The included accessories are great for first-time sewing machine owners, providing you with everything you need to get started. 

The machine comes with an all-purpose foot, a zipper foot, buttonhole foot, button sewing foot, seam ripper, lint brush, quilting guide, a needle set, bobbins, screwdriver, auxiliary spool pin, and spool pin felt. That’s a lot of great extras for you! 

These extras are all stored in an accessory tray on the machine, making them conveniently located for your every need. You also get a soft-sided cover that will protect your sewing machine from dust or any debris while it is not in use. 


You won’t need to worry about any issues with this sewing machine thanks to Singer’s impressive 25-year warranty for the 4423! Should anything go wrong, you can rest easy knowing that you will be covered. We do need to chat about the warranty, though, as it can be a little confusing. 

The warranty is split into a few sections. The 25-year warranty covers your sewing machine head. Your wiring, motors, stitches, speed control, light assembly, and electronic components are covered with a two-year warranty. A 90-day warranty only covers the machine’s adjustments, bulbs, belts, attachments, and rings. 

We recommend checking all these components thoroughly on arrival so that should any arrive damaged, you can get them replaced within the warranty period. The head warranty also has no replacements for wear and tear; you will need to pay for these replacement parts yourself. This is a standard provision across electronics. 

It is also worth noting that the warranty does not apply when purchasing a second-hand Singer 4423. It is best to purchase the machine new so that you are covered from any damages. Thankfully, few customers reported issues with the machine, so you should never need to worry about the warranty periods!

Along with the warranty, there is also detailed information in the instruction manual that comes with the machine. You can also download a PDF copy of this always to have it at hand should you require it. There is also a wealth of videos available to provide you with any help. Great for first-time sewing machine users wanting to learn!
