  CHAMDRILLJET New Interchangeable Head Drills  
  ISCAR’s family of interchangeable carbide drill heads has been enhanced again with the addition of CHAMDRILLJET. All of the familiar CHAMDRILLJET advantages have been expanded for the 8 to 9.9 and 25 to 32.9 hole range. The new drills also feature frontal cooling.

The drilling depth-to-diameter ratios are 3xD and 5xD. All drill bodies have internal coolant holes with the coolant ports adjacent to the cutting edge for the most efficient flushing and chip evacuation. The drill heads have large radial stoppers to bear the tensional cutting forces.
The drill shank has no flange on it.
ICP, ICM and ICN drill head geometries are available in 0.1 mm drill diameter increments.
ICK drill head geometries are currently available in whole and mid sizes.

CHAMDRILLJET features four various, standard drill head geometries designed specifically for optimal performance and maximum reliability when used on the different materials.

• ICP – For use on steel (ISO P). The drill head has a 25° positive cutting rake and a honed cutting edge.
• ICM – For use on stainless steel (ISO M). The drill head has a 25° positive cutting rake and features a T-land on the cutting edge.
• ICK – For use on cast iron (ISO K). The drill head has a 10° positive cutting rake and is designed with a honed cutting edge and two peripheral chamfers.
• ICN – For use on aluminum (ISO N). The drill head has a 30° positive polished cutting rake and is manufactured with a sharp cutting edge.
ICN (for aluminum) is made in ISCAR’s uncoated submicron grade IC08. All other geometries are made in grade IC908 with a TiAlN PVD coating. IC908 is ISCAR’s most advanced grade for excellent performance in a variety of drilling applications.

The head geometries were designed according to the material to be cut, in order to provide optimal chip evacuation, drilling head life, surface finish and reliability.
CHAMDRILLJET drill bodies have a 30º flute helix on the 3xD drills and 25º flute helix on the 5xD drills. This system provides excellent hole accuracy and straightness.
