An apparatus is an implant-dentist more readily identifiable visual segregation amongst their oral-surgery arbor-tools used conjunction with a conventional hand-held power/rotary-tool. The arbor-tools generally has at least a tri-echeloned set, wherein are included progressions of drill-bit lengths and companion thread-taps appearing in three different diameters. Additionally, the drill-bit shanks are optionally provided with a radial-flange serving as an automatic depth-stop device and these radial-flanges may include a distinctive annular-marker device serving to readily indicate the length of the selected drill-bit, thereby obviating usual procedure of stopping to confirm via the obscure conventional alpha-numeric indicia.

The invention relates to a package for a drill. The package has a protecting portion arranged to house a cutting portion of said drill in a contact free manner and a locking portion arranged to hold a tool engaging portion of said drill. The locking portion and the protecting portion are movable relative each other and the drill is releasable from the locking portion by a movement of the locking portion relative the protecting portion. The protecting portion is allows the user to clamp the cutting portion of said drill by pressing the protecting portion and thereby establishing a contact between the protecting portion and the cutting portion of said drill. The invention also relates to a method and an arrangement.
