Technical information for Threading Technical information for Threading Infeed Angle Selection And Chip Formation Typical Chip Formation Standard and slanted Anvils Infeed Angle 0° Benefit:Cutting edge is Y protected from chipping Negative by both sides in cut. Helix Problem :Both sides of insert are heated by the wokpiece. Produces " Vee " chips which Insert can be very difficult to handle. TTOOLTEC toolholder and boring bar pockets have a built-in 1.5 helix compensation angle. This angle may be adjusted to match the helix angle of the thread being produced by replacing the anvil. Toolholder Toolholder Infeed Angle 30° Benefit :Chip is curled away from thread form. Positive Helix Angles Negative Helix Angles Problem: Trailing edge maydrag rather than cut, whichmay cause chipping.
