ISCAR is introducing CHAMIQDRILL family

The CHAMIQDRILL from ISCAR features a unique design, utilising the carbide flexibility for self-locking; eliminating the need for clamping accessories.

The features include, HFP-IQ Drilling Heads, available in the drilling range of 33-40 mm diameters in 0.5 mm increments, unique self-centering geometry enables using up to 5xD long overhang without the need for a pilot hole operation, produced from grade IC908 – a PVD coated fine submicron grain substrate, single type geometry is suitable for ISO P/K materials

The innovative pocket design eliminates the need for an open/flexible construction, which may weaken the tool, thus enabling a high number of drilling head indexes on each tool. It is available in 3 and 5 diameter to length ratio in 1 mm increments. The body is produced from special steel for high durability. A special stopper prevents the drilling head from being extracted upwards from the pocket. Long stoppers provide high resistance to cutting forces, enabling applications under very high cutting conditions. High flute helix and polished flute surfaces provides a smooth and easy chip evacuation process. An internal coolant supply provides efficient cooling and lubrication during the drilling process. The robust structure with concave cutting edge design enables drilling at high feed rates, providing very accurate IT8–IT9 hole tolerance.
