My copending application Ser. No. 41,421 filed Apr. 23, 1987, now abandoned disclosed a (throw-away) packaging construction for Sterilized Dental Bits. These drill bits are so constructed and arranged that it is unnecessary for the Dentist or his assistant to touch the drill bits prior to the time that the bits are used with respect to each particular patient. The necessity for this construction came about to overcome the fear that many dental patients have of being contaminated by a communicable disease such as “Aids”, where the Dentist or his assistant touches the drill bits used to drill out decayed portions of teeth that need “filling”, or where a drill bit is used that has been previously used on another patient. My copending application discloses individual drill bits packaged in individual containers and closed by individualized closure members after the drill bits have been sterilized. In the event that difficulties are encountered in removing the drill bit from the chuck or the container, one end of the container package can be provided with a circumferential extension having cross slots into which the shank of the drill bit can be clamped to force the drill bit to be released.
