182220 Front reamer BECK

HSS-E Z
4-6
P K N
Cu, AI

No. 030810, HSS-E, straight shank, right-cutting, straight flutes, works standard.
Design
The teeth have a broad cylindrical grind chamfer on the perimeter, which serves to guide the rea-
mer but does not cut. Every second flute is cut through for better feed of the lubricant to the cut.
The front cut overcomes eccentricity; front reamers do not follow the pre-drilled hole.
Tolerance d1: H7
d3: inside diameter at the front cut.
