Singer Sewing Outlet's comments on Heavy Duty machines

Singer's award-winning Heavy Duty machines are fantastic when you want the strength to sew a pair of curtains, repair jeans, quilt or upholster, but they can also sew lightweight fabrics just as a regular machine would. There are no real drawbacks to choosing a Heavy Duty machine.

The combination of a more powerful motor, more metal components and a dual pulley system driving the needle gives you extra penetration power to tackle heavier projects when needed, on a long-lasting, durable and dependable machine. They also sew faster than a regular machine at full speed should you want to, yet are completely controllable down to 1 stitch per second using the foot control. An adjuster under the foot control can also lower the machine's maximum speed if you're just starting out.

The M6335 sits at the top of the mechanical range, with a number of additional accessories that you do not get with the other models. It has a good number of stitch patterns (32) as well as a 1-step automatic buttonhole and automatic needle threader, plus built-in stretch and overlock stitch patterns. Its total ease of use makes it a popular choice with sewers of every level, from beginner to advanced.

Customer photo review of Singer Heavy Duty M6335 Denim Edition Sewing Machine

I didn't make a lot, but so far I'm very happy with purchase. It's certainly more suitable for thicker fabrics, it's a heavy duty sewing machine as it's supposed to be. Enjoying using it and hope for a long durability.

Singer Heavy Duty M6335 Denim Edition Sewing Machine

Pleased with machine Couple of small observations The guide for top thread and for spool loading is shared which is annoying, a separate guide would be better To reverse you have to hold the button down which is also annoying The auto needle threader is not great and only works about 30% of the time so you end up threading the needle manually The bobbin pick up for threading works well. Extracting the bobbin is fiddly on my old singer there was a lever to lift the bobbin out. Also the thread has to be fed in a slot which is also fiddly Not as heavy duty as I was expecting struggles with single webbing strap The machine did not come with a manual which is poor form. The machine it self arrived extremely promptly from Singer Outlet, however nearly two weeks on and I am still waiting for the additional package of needles, bobbins, feet etc Generally pleased with machine despite these observations

As a beginner the prospect of buying, and learning how to use, a sewing machine was a little concerning. Especially as my need was to tackle heavy materials like laminated canvas and leather. The support for the product was excellent, I made good use of the videos. The machine itself worked well out of the box and I have quickly gained confidence. The HD handles my materials without issue, working smoothly and controllably.

I am returning to sewing after a long break. My daughter bought a Singer during lockdown which I borrowed. So impressed, bought my own and have thoroughly enjoyed relearning the art. Great machine, easy to use, very powerful. Quite noisy compared to some, but so what! Great range of stitches both ornamental and useful, including the overlock which is great for tidying fraying fabric without having to hem. Automatic buttonhole is fantastic, once I got the hang of it. all round smashing machine
