APPLICATION
For drilling from solid, spot drilling on inclined or convex surfaces, chain drilling
Ideal for general mechanical engineering, and the automotive, mass production and aerospace industries
TOOL
Square, positive indexable insert with four cutting edges
Ideal for drilling into solid material with the D4120 indexable insert drill
Special design of centre and outer inserts to compensate for the cutting forces
Indents in the rake face signify the number of the cutting edge
BENEFITS
Increase in productivity through higher cutting data
Adherence to minimal hole tolerances due to the optimum balance of forces
Reduced costs thanks to four cutting edges
High level of process reliability due to force-fit indexable insert clamping
