5720.040HP Fine Cross Cut – EF

Suitable for all dental materials. It smooths the surface and it enables accurate operation on any structure.

Measurements:

Head Size: 040mm

Head Length: 14.1mm

Uses:

• Designed for fine cutting on all metals, acrylic and stone.
• Tungsten carbide instruments for precise preparation.

Optimum material reduction and a high-quality surface finish on all types of material. The optimally
coordinated blade geometry and cutter designs ensure a long service life and high cutting capacity when preparing stone, acrylic, metal, precious metal, titanium or porcelain.

The specially developed blades with relief channels made from high-grade HIP tungsten carbide alloy are extremely cost-effective.

Operating Information

Correct application

• Use only technically perfect, serviced handpieces.
• Clean the handpiece chuck regularly.
• Instruments must be inserted as far as possible.
• Use eye-shield and dust-extraction.
• Instruments should reach the operating speed before
  they are applied to the work piece.
• Avoid canting or levering the instrument as this
  increases the risk of breakage.

Working Pressure

Excessive working pressure must be avoided.
Pressure: 0.2 – 5 N

Worn Instruments

Fractured and incorrectly shaped blades cause vibrations.
Bent or non-concentric rotary instruments must be
disposed of.

Recommended Speeds

Non-adherence to the maximum permissible speeds
increases the risk of accidents.
Please Note:
Using cutters marked with the indentation codes 50 – 85
the grinding movements must be done under constant
pressure operating the instrument at the recommended
speed.
Danger of Injury – soft, timid or hesitant use of large
intended instruments causes rock or toss vibration with
the possibility of a shaft breakage.
