[ ! ]When machining the radius, corner C, and flat bottom blade, grinding of the bottom blade is performed.
[ ! ]Machining the blade edge shape shortens the blade length (ℓ) and the total length (L) by approximately D x 0.5 (up to 5 mm).

[ ! ]For the standards for the blade length (ℓ), total length (L), and shank diameter (d), refer to the page for the relevant model number.
[ ! ]When used together, specify the length under neck (KN) and the total length (LC) such that they are in the range given by LC ≥ KN + 3d + 5.
[ ! ]Specifying the length under neck (KN) indicates that the shank clearance diameter will be the blade diameter less 0.2 ~ 0.5 mm.
