Ingersoll’s Hi-QuadF high-feed milling cutters are available with a 13-mm IC insert for 0.088" depth of cut or a 19-mm IC insert for 0.145" depth of cut. The inserts offer four cutting edges and a choice of eight different cutting edge geometries. The positive axial insert orientation is said to create a high-sheer, free-cutting nature. Chip thinning is leveraged to a factor of 5× when calculating feed rates. Cutter performance and insert seating stability are ensured with an insert screw design that secures the insert in the pocket.  


  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.

  • Inserts For Difficult Materials

    Economic efficiency is an important consideration when choosing tools for challenging metals.

  • Start With The Right Speeds And Feeds

    Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
