Material: High performance Carbide of the best grade.
Workmanship: Special process assures a strong bond between Carbide and steel, not affected by temperature. Exact concentricity. Unusual durability, resistant to wear, even under unfavorable conditions. Blades designed for the intended use in a constructive manner, especially for the particular diameter and size.
Application: Leverage and planing motion must be avoided to prevent breakage. Use only with true running handpieces and chucks. Instruments with heavier shaft will afford greater safety, particularly heavy duty laboratory cutters and trimmers. The maximum working presure increases according to the diameter from 0,3N—5N. FG Burs with long shank not recommended for use above 120,000 rpm.
The following speeds are for guidance only. Variations above or below these speeds according to manner of use and particular material may also be satisfactory. Always use safety glasses.

- Maximum contact pressure: 0,3—2 N
- Instruments have to be fully inserted in chuck
- Ensure that chucks of the handpiece are cleaned regularly
- Avoid leverage and jamming
- Use eyeshield and aspiration
- Maximum admissible speed has to be observed (indicated on each BUSCH box and in our chart above)
- Instruments should reach the operating speed before they are applied to the work piece
- Sufficient cooling water spray (minimum 50 ml/min) is to be used for certain preparation application in dental practice
Instruments have to be disinfected and, if necessary, sterilized before use.
Disinfection and cleaning:
- Put instruments into a bath with suitable disinfection and cleansing liquid.
- Afterwards, clean the instruments manually or by ultrasonic bath.
- After cleaning the instruments, dry immediately.
- Following the disinfection and cleaning, the instruments can be sterilized in the autoclave, chemiclave, or hot-air sterilizer.
- Before the sterilization, the instruments have to be put into a case or foil permeable to germs and suitable for sterilization.
- After the sterilization, the instruments in the case or foil should be kept in a dry and dustfree place.
