Abstract

155,452. Clare, C. H., and Heaton, J. Dec. 12, 1919. Reamers.-A reamer has two or more spiral grooves a with the upper sides inclined to,_ and the lower sides at right-angles to the axis of the tool, forming end cutting points a<3>. After the cutter is worn, it is ground off for a short length from the end, and new cutting-points are formed at its end. Vertical chip-clearing and lubricating grooves b may intersect the spiral grooves. The grooved body forms a steady for the tool in use. Specifications 11577/85 and 23554/04 are referred to.
