AddDoFeed

Small diameter high feed milling solution

A great cost saving alternative for solid carbide endmills

Applications & Features

Applications

Deep shoulder milling Face milling Slotting Pocketing Ramping Plunging Hole enlarging

Features

1. Small inserts, close pitch design

– Small insert design allows higher machining efficiency and reduced tool costs due to increased number of inserts

AddDoFeed 02 inserts for cutter diameters ø8 – 25 mm

Small inserts enable close pitch and rigid design

Number of inserts per diameter comparison

2. High tool rigidity

– High tool rigidity is achieved by using higher material support below each pocket and fine thread screws, allowing this small-sized cutter to successfully withstand higher cutting force

The robust design of AddDoFeed 02 insert provides excellent fracture resistance

Shallow-pitched fine threads prevent screw from self-loosening due to higher number of threads in contact

3. Effective chip evacuation

– Chip jamming and re-cutting are challenges when machining narrow grooves and small cavities. AddDoFeed insert features an inclination on the cutting edge optimized for effective chip formation, which eliminates chip re-cutting and prolongs insert tool life
