78 ISCAR GENERAL PURPOSE DRILLINGExchangeable Drilling HeadsHFP %u2026-IQ and IFP %u2026-IQ exchangeable drilling heads are made of IC908 TiAlN PVD nano layer coating grade for prolonged and predictable tool life. The cutting-edge geometry of SPADE-CHAMindexable heads provides a mechanically efficient cutting action, reducing power consumption and noise, and increasing material-removal rates. The HFP %u2026-IQ drilling heads have a unique self-centering geometry that enables using up to 8xD long overhang without the need for a pilot hole operation, which is mainly intended for machining ISO P and ISO K materials. The IFP %u2026-IQ drilling head is designed for machining ISO P, ISO M and ISO S materials and enables using up to 5xD long overhang without the need for a pilot hole operation. HFP ...-IQIFP ...-IQDrill BodyThe design of the SPADE-CHAM body is made from special steel for high durability. High flute helix and polished flute surfaces provide a smooth and easy chip evacuation process. The internal coolant supply provides efficient cooling and lubrication during the drilling process.Clamping PocketThe SPADE-CHAM line employs an innovative insert positioning and locking mechanism that eliminates the need for clamps or screws commonly found on drills for larger diameters. This design allows for easy indexing on the machine to reduce setup. 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. The pocket design eliminates the need for an open or flexible construction, which may weaken the tool, thus enabling a high number of drilling head indexes on each tool. The SPADE-CHAMclamping mechanism ensures insert security and long body life.
