ISCAR TECH TALK - ISCAR Modular Exchangeable Drilling Heads for Large Diameter Deep Drilling

ISCAR Introduces New Exchangeable MD-EXTENSION Holders That Can Increase the Drilling Depth by an Additional 200mm. ISCAR introduces new Modular Exchangeable drilling heads for Large Diameter Deep Drilling. The MODUDRILL family provides a significant increase in drilling depth by an additional 200mm using only two bodies to cover the existing diameter range: one by use of 33-36 mm and the other by 37-40 mm. Each drill body can carry any one of the two head types. The two available drilling heads were designed for different applications and cutting conditions, required hole accuracy and surface finish. When using the MD-EXTENSION, a short pre-hole of at least 1XD deep with H8 hole tolerance should be prepared to guide the long drill for all drilling head types. MD-BODY Modular bodies that can carry different types of drilling heads. The tool bodies are produced from high strength steel for high durability. The tools have a small core with central coolant hole for efficient chip evacuation. ISCAR's new patented connection withstands high torque, and the high flute helix with a polished surface provides a smooth and easy chip evacuation for chips of all sizes. MD-DFN Modular Heads • Mount HFP-IQ CHAM-IQ-DRILL solid carbide heads • Robust structure with concave cutting edge design enables drilling at high feed rates, providing very accurate IT8-IT9 hole tolerance • Unique pocket design enables many drilling head indexes • Special axial stopper prevents the drilling head from being extracted during retraction. • Large radial head stoppers provide high resistance to cutting forces, enable very high cutting conditions HFP-IQ Drilling Heads • Available in a 33-40 mm diameter drilling range, according to the standard items list • Unique self-centering geometry enables long overhang without the need for a pilot hole operation. • Produced from grade IC908 – a PVD coating on a fine submicron grain substrate • Suitable for steel and cast-iron ISO P/K material groups. I would like to remind you to download the ISCAR World app which features the revolutionary NEO-ITA for achieving optimal machining result. https://www.iscar.com/newarticles.aspx/countryid/1/newarticleid/2978 #ISCAR; #Hole-Making; #Drilling; #Deep-Drilling; #Modular-Exchangeable-Drilling-Heads;
