Title:
REAMER
Document Type and Number:
WIPO Patent Application WO/2020/003679
Kind Code:
A1
Abstract:
This reamer is provided with a base metal and a plurality of outer circumference cutting edges that are made of a super-hard tool material and provided on the outer circumference of the base metal. The base metal extends from the tip to the rear end. The base metal is provided with a plurality of flutes from the tip toward the rear end. Thinned sections are provided, as center-of-gravity adjustment sections for adjusting the misalignment of the center of gravity with the center of rotation, in at least a portion of the region between the terminal ends of the flutes to the rear end of the base metal. Due to the center-of-gravity adjustment sections, misalignment of the center-of-gravity with the center of rotation is smaller than the case in which the center-of-gravity adjustment sections are not provided.
