The computerised Singer Heavy Duty step-up

More control and creativity than a basic mechanical model

The HD6605C is designed for sewists who want the strength and speed associated with Singer Heavy Duty machines without being limited to a small mechanical stitch library.

Its electronic controls provide direct access to utility, stretch and decorative stitches, while the LCD screen displays the selected stitch number and its current settings.

Programmable needle up/down, six one-step buttonhole styles and adjustable stitch length and width make it easier to produce accurate garments, home décor, bags, quilts and creative sewing projects.

A stainless-steel bedplate, full metal internal frame and enhanced piercing power provide a stable foundation for frequent domestic sewing.

Heavy duty does not mean industrial

The Singer HD6605C is a powerful domestic sewing machine built for garments, alterations, crafts, quilting, denim, bags and home décor.

It is not an industrial walking-foot machine and is not intended for continuous production, thick saddlery leather, heavy webbing assemblies or commercial upholstery work.

Material capability depends on the total number of layers, seam thickness, fabric density, needle type, thread size and sewing technique.

6 Automatic one-step buttonhole styles

Complete each buttonhole through one continuous machine-controlled sequence.

1,100 Maximum stitches per minute

High-speed domestic sewing for long seams, garments, curtains, quilts and larger projects.

Speed when you need it, control when you do not

High-performance domestic sewing

The machine can sew at up to approximately 1,100 stitches per minute, supporting faster completion of long seams and substantial projects.

Sewing speed remains controlled through the supplied foot controller, allowing the operator to slow down for corners, detail and difficult seam intersections.

Beginners should practise pedal control before attempting maximum speed.

Stop exactly where the project needs you

Programmable needle up/down

Set the needle to stop in the down position when pivoting around corners, sewing appliqué or guiding curved seams.

Choose needle-up stopping when removing the project or repositioning the fabric after an ordinary seam.

This small electronic convenience makes detailed sewing feel more controlled and efficient.

Easy bobbin setup and visible thread supply

Top drop-in Class 15 bobbin

Insert the transparent Class 15 bobbin from above beneath the clear bobbin cover.

Follow the marked threading path to bring the bobbin thread into position without removing a separate bobbin case.

The clear cover allows you to monitor the remaining thread supply before it runs out in the middle of a seam.

  • Top-loading access
  • Transparent bobbin cover
  • Visible thread supply
  • Class 15 transparent bobbins
  • Four bobbins included
  • Easy cleaning access
Faster upper-thread preparation

Built-in assisted needle threader

Follow the clearly marked upper-thread path and lower the threading mechanism beside the needle.

The threader helps pull the upper thread through the needle eye, reducing strain and speeding up thread changes.

Always raise the needle fully and use the threader only with compatible needle sizes.

Control fabric feeding across different materials

Adjustable presser-foot pressure

Presser-foot pressure affects how firmly the foot holds fabric against the feed system.

Reduce pressure when selected lightweight or delicate fabrics are being stretched or marked unnecessarily.

Increase pressure when additional contact is needed to help feed heavier or less stable material.

A durable foundation beneath the electronic controls

Full metal internal frame

The internal metal frame supports the needle mechanism, drive system and principal sewing components.

This provides a stable foundation for high-speed domestic sewing and helps maintain alignment through regular use.

The external shell remains moulded for manageable weight, comfortable handling and access to the machine’s controls.

Smooth fabric movement across the machine bed

Stainless-steel bedplate

The metal surface around the needle and free arm gives fabric a smooth path as it approaches the feed dogs.

This is particularly useful when handling denim, canvas, vinyl, quilting cotton and other materials that can drag against a rougher surface.

Keep the plate clean and free from adhesive residue to preserve smooth fabric movement.

Manual control for quilting and creative sewing

Drop feed for free-motion work

Slide the drop-feed control to lower the feed dogs beneath the needle plate.

The project can then be moved manually for free-motion quilting, thread drawing, darning and selected creative techniques.

Fit an appropriate optional darning or free-motion foot before beginning.

Additional room beneath the presser foot

Extra-high presser-foot lift

Raise the presser-foot lever beyond its normal position for additional loading clearance.

This helps when positioning thick hems, quilt layers, bag seams and bulky seam intersections beneath the foot.

Extra lift provides clearance only. The machine must still be able to penetrate and feed the complete material assembly safely.

Three useful needle positions

Position stitches for zips, piping and topstitching

Choose left, centre or right needle positions when supported by the selected stitch.

This helps place stitching accurately beside zips, piping, edges and existing seam lines.

  • Centre construction seams
  • Left-position topstitching
  • Right-position edgestitching
  • Zip insertion
  • Piping application
  • Precise seam placement
Narrow tubular sewing access

Convertible free arm

Remove the accessory compartment to expose the machine’s free arm.

Sleeves, cuffs, trouser hems, bag openings and other tubular areas can then be positioned around the narrower sewing surface.

Refit the compartment for a larger flatbed and integrated accessory storage.

More support for quilts and larger projects

Bonus extension table included

The current Direct Sewing package includes a Singer-compatible extension table for the computerised Heavy Duty range.

The table increases the flat working area around the machine and helps support quilts, curtains, bags and larger fabric pieces.

Keeping more project weight level with the needle can reduce fabric drag and improve control.

Bonus inclusions are based on the current Direct Sewing offer and may change when promotions or package contents are updated.

Realistic material capability

Built for demanding domestic projects

The HD6605C is well suited to everyday garment fabric, denim, cotton drill, bag material, selected canvas, faux fur and light leather applications.

Use a suitable Singer, Schmetz or Organ needle, quality thread and an appropriate presser foot for the material being sewn.

Test layered seams before beginning the final project and avoid forcing material beneath the presser foot or pulling it behind the needle.

  • Garment denim
  • Cotton drill
  • Quilting cotton
  • Stretch fabrics
  • Selected light canvas
  • Bag-making fabric
  • Faux fur
  • Selected thin leather
  • Home décor material
  • Layered domestic projects
