【Ultrasonic Cutter】 Cemented carbide blade HA07.
Hello.
Today, we would like to write about “Cemented carbide blade HA07”.
The shape is same with “standard blade HA04”, but it’s more harder. It’s useful for a work, cutting hard material which standard blade get damage easily.
Recently, we have questioned from ultrasonic cutter user,
“For cutting wood, which blade is proper, HA04 or HA07?”
Standard blade HA04 Cemented carbide blade HA07
Wood is hard material, and because it doesn’t melt, you need to cut with just blade power.
(For cutting plastic, it melts, so it’s easier to cut than un-melt material)
For this work, which blade would be proper?
Decide with “quality” or “quantity” of work.
The answer of question we would say is,
“If you cut many woods, we recommend standard blade HA04. If you don’t use blade so much and want improve quality of work, we recommend cemented carbide blade HA07.”
Basically, HA07 is better than HA04 for cutting wood. However, when you see a both blade’s price, you could buy 4 sets(160 blades = 40 pcs. for each set) of HA04 cheaper than HA07(1 pcs.).
※HA04(800JPY) HA07(3,500JPY)
Cemented carbide blade is hard, but if you would keep work on wood along, it would be reasonable to change standard blade each time(maximum 159 times) when it get damage.
Decide with your “purpose” and “price” for choosing blade.
There are more than 40 types of replacement blade, and each price, shape, utilities are different. Let’s think for price and your work purpose, and judge which to buy as a whole.
