Chip damage from long stringy chips
Chips cause unpredictable damage. In general, the longer the chips, the harder it is to control and the more damage they cause. Long stringy chips wrap around boring bars, fill the bottoms of holes, catch on the chucks, cause mechanical problems with loaders, and in many cases require manual removal. Broken chips that can fall away, or that can be blown out of the cutting zone with coolant force and away from the part and tool are almost always more desirable. Many people don’t understand the difference between wear and damage. Wear is a predictable part of any mechanical process. Damage, on the other hand, is random, producing the same bell shaped curve that any random event with enough samples must produce.
High force coolant breaks chips and keeps them away from the tool.

| Low-pressure coolant allows a long shear zone that does not break chips in many materials. The result is long uncontrollable chips. | High Pressure and volume directed into the chip-tool interface never lets the temperature get out of control. The shear zone is short and the chips break over the base material. The part itself is acting as a chip breaker. | |||
