BTA – BILLET – UNIDEX Deep Hole Drilling.
IMPROVE PRODUCTIVITY AND COST REDUCTION
KUSTS increase productivity and also obtained an excellent surface finish. Drilling was seamless without interruptions.
Chip formation is short, facilitating efficient evacuation.
The UC2220 grade exhibits superior performance on SUS316 stainless steel, resulting in a notable enhancement in tool life compared to the competitor.
This successful outcome has enabled us to secure several additional sizes from the competition.
