New Modular Exchangeable Drilling
Heads for Large Diameter Deep Drilling
Highlights
ISCAR is expanding large diameter drilling options with the new MODUDRILL line, which features two different types of exchangeable heads covering a 33 to 40 mm drilling range.
The drilling heads are attached to 400 mm long drill bodies.
The new MODUDRILL family uses only two drill bodies to cover the full range: one for 33-36 mm and the other for 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 - cutting conditions, required hole accuracy and surface finish.
