Features

01/

More efficient to cut through materials
Circular blades can make a cleaner cut and requires less energy than straight blades when cutting through materials.

02/

Produce less waste than other types of blades
A circular blade leaves a smaller opening than a straight blade, allowing less material to be lost during the cutting process.

03/

Easier to control (more stability)
It is easier to control a circular blade because it only needs to be rotated to the desired speed and then used to cut through the material. And it is a lot easier than using a saw or a knife, which can be very difficult to control.

04/

Safer to use (fewer cuts or injuries)
Circular blades are not as sharp and are not as pointy as other blades, which means that they are less likely to cause cuts or punctures.

Q: Can I get small quantity samples for test?

A: Yes, we support small sample orders. Sample cost will be refunded when you place formal bulk order later.

Q: How long is the service life of SKD11 round blade?

A: Under normal film slitting working conditions, service life ranges from 800 to 3000 hours, affected by cutting material and machine speed.

Q: Do you provide food-grade round blades for food machinery?

A: Yes, we supply fully polished food-safe circular knives with anti-corrosion treatment, suitable for food processing equipment.

Q: Do you face up or down with a circular saw?

A: Yes, we supply fully polished food-safe circular knives with anti-corrosion treatment, suitable for food processing equipment.

Q: Can you make blades according to my old sample or technical drawing?

A: Absolutely. You can send us physical samples or CAD drawings, our engineers will optimize the design and produce customized blades.

Q: Absolutely. You can send us physical samples or CAD drawings, our engineers will optimize the design and produce customized blades.

A: Our blades support re-grinding service. You can send used blades back for re-polishing to save replacement cost.

Q: What is the most common circular saw blade?

A: 7-1/4 inches
The most common blade diameter is 7-1/4 inches. Most saws with blade capacities of 6 inches or more can cut through 2-inch dimensional lumber at a 45-degree angle in a single pass.

Q: What circular saw blade gives the cleanest cut?

A: Replace the 24-tooth blade that came with the saw with a 50- to 60-tooth blade for cleaner crosscuts in solid wood, veneered plywood, and other sheet goods. For general use when cut quality isn't critical, use a 40-tooth blade. If you're ripping solid wood, switch back to the 24-tooth blade.

Q: What size circular saw will cut a 2x4 board?

A: If you are cutting lots of 2 x 4 boards then a circular saw will make the job a lot quicker and more efficient. Using a five and a half inch blade will work really well for this job.
