We tried various products of other companies, etc., and became this product in terms of performance and cost. It is mainly used for cutting thin steel sheet products at shop floor. There is a sense of profit when considering that there are one gift when purchasing 10 sheets with a product manufacturer campaign.
Attached to a Panasonic power cutter, cut general steels with 19 mm - 42 mm diameter and thickness 1.2 - 2 mm. The metal teeth attached to the product, even when cutting soft iron, the chips were missing. Although it can not be re-polished, since this product is a cermet chip, it is not chipped or jumped and it only wears out, so you can reuse it again by diamond disc etc. (We are using polishing machines made by Nishikaki and re-polishing.) However, depending on the degree of regrinding, adjustment (polishing) of a limiter (restricted tooth) that adjusts biting of the blade is also required. Moreover, when feeling weakness from light initial initial cutting performance rather than regrinding after feeling it "can not run out", product life tends to be sustained by resharpening. One by one on the sticky side. In order to maintain the cutting ability more, the cutting speed according to the shape and thickness of the object is learned by the operator from experiences and continuous work is to be avoided. For experts and inexperienced workers, the amount of work is about twice as much under the same conditions.
