How to Choose the Right Taegutec DN-55 Insert

Selecting the correct Taegutec DN-55 insert involves three decisions:

1. Material → Grade: Steel → TT7015 / TT8115. Stainless → TT8020 / TT9225. Cast iron → KT-series. Aluminum → US-series.
2. Sub-designation → Operation: General turning → DNMG. Finishing → DNMG. Heavy roughing → thicker section.
3. IC size → Tool holder: Smaller IC fits compact holders. Larger IC for heavy-duty work.

Tip: For stainless steel work, Taegutec TT9225 (CVD M-grade) provides superior wear resistance. For aluminum, use uncoated US-series with sharp-edge geometry.
