A method for producing the same, and rotary cutting tool with a margin that has been sealed

摘要

Rotary cutting tool (10) includes a body of generally cylindrical shape having a first end (12), a second end (14), a longitudinal axis therebetween and (16). Mount (18) is disposed around the end (12) of the first (20) is disposed around the end (14) of the second head with a (D) outer diameter, the head ( body recess with (d) an outer diameter smaller than 20) (22) is disposed therebetween. Configured to engage the cut workpiece (20) head. And extending along at least a portion the body recess (22) A plurality of grooves (24) and, along the (20) head the second end of the body having a substantially cylindrical (14). Includes margins flank multiple (30) is arranged a groove, each of which is adjacent to (24) between the inner distance (t) outside diameter head (20) (D) to the head (20) which is provided, extending the second end of the body of substantially cylindrical shape (14), terminates at (32) margin seal head (20).
