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 evacua
