New QUICK3CHAM Heads for Boring and Enlarging Existing Holes

When surface finish, diameter, straightness, or roundness requirements are closer than traditional drilling operations can produce, it may be necessary to add a drill, endmill or single-point boring tool to the operation, often at the expense of poor chip control.

When surface finish, diameter, straightness, or roundness requirements are closer than traditional drilling operations can produce, it may be necessary to add a drill, endmill or single-point boring tool to the operation, often at the expense of poor chip control.

Iscar introduces a new line of replaceable carbide heads for counterboring operations. The F3B heads feature chip deflectors for excellent chip control in a wide range of materials. They are offered in 0.1 mm (0.004") increments from Ø12-25.5 mm (0.472-1.004") and mount on standard tool bodies from the QUICK3CHAM drilling line. Three flutes provide improved quality three times faster than single point.
