Mũi khoan đầu bằng Flat Drill 2 Me cắt bằng carbide (2FDR)
-
Mũi khoan phẳng dùng cho vật liệu đến HRc50, thép đã tôi luyện (pre-hardened), thép hợp kim, gang.
-
Kiểu lưỡi phẳng (flat type) cho phép gia công xuất sắc trên nhiều bề mặt nghiêng và bề mặt cong.
- Thiết kế rãnh xoắn 20° giúp thoát phoi cực tốt và đảm bảo quá trình khoan ổn định.
-
Giảm thiểu tối đa bavia (vẹt thừa) khi khoan xuyên.
-
Lớp phủ HR mang lại khả năng chịu nhiệt và chống mài mòn tuyệt vời, kéo dài đáng kể tuổi thọ dụng cụ.
HRc50이하, 프리하든강, 합금강, 주철 가공용 플랫 드릴
-
밀날 플랫타입으로 다양한 경사면과 곡면 드릴가공에 탁월한 성능을 발휘합니다.
-
20도 헬릭스를 채택하여 칩배출 성능이 매우 우수합니다.
-
관통 드릴 작업시 버 발생을 최소화 합니다.
-
HR 코팅으로 내열성과 내마모성이 우수, 긴 공구수명을 실현하였습니다.
