D-Z-BF Taps

Chip Breaker Taps

The Emuge Rekord D-Z BF tap is a "chip breaker" design which is especially well suited for blind hole applications on automatic lathes and multi-spindle machines. The slow spiral flutes is also helpful in thread holes beginning with an increased diameter (counterbore or enlarged bore). Provided with internal coolant supply, this tap type will help to solve chip problems on CNC machines.

Specialized BF Grind - “Bright Face” grinding in combination with a special edge preparation ensures that chips will break. Short chips will be evacuated without “bird nesting”.
