Method and material for wrapping items using a wrapping material made up of separate wrapping portions of a predetermined length. The wrapping portions are attached and released at their ends using a Z-lock system including a discrete laminate. The discrete laminate of the Z-lock system holds the wrapping portions together during manufacturing but can also easily release or separate the wrapping portions at a desired point in the wrapping process. The separating of the wrapping portions exposes an adhesive that is use to securely bond at least one wrapping portion to the item being wrapped at the end of a wrapping cycle.

A drill comprises a shaft with chip conveying flutes and a drill head at its forward end with at least two cutting inserts. Each cutting insert is provided with at least one cutting edge which is delimited between a chipbreaking surface and first relief surface and which includes an outer straight edge. In the proximity of the center axis of the shaft, a curved cutting edge section is provided, to which there is connected an adjacent enforcement bevel. The cutting edge is in direct proximity to a center axis, and is terminated by a chisel edge between the cutting inserts to serve as a centering core portion. The curved cutting edge section is inwardly followed by a primary straight portion without an adjacent enforcement bevel in a direction that is oriented at an angle of between approximately 40–50° in relation to a horizontal line that extends through the center axis of the drill.
