ur proprietary grinding technology has achieved ultra-thin blade thickness, a feature that had not yet been practically applied in cemented solid metal saws.
Minimum blade thickness can be manufactured up to 0.02mm for φ45, 0.04mm for φ60, and 0.10mm for φ100. It enables fine cutting and fine groove cutting in areas previously considered impossible.
Product Features
-
It is finished to a “mirror” finish using our unique grinding technology.
-
Only our company has a back taper (medium to low gradient) at this thickness.
- Comparison between hair and blade tips
- Measurement with a micrometer
