FTO-M-GDXL is a new type of drill for OSG Precision Tools Co., Ltd. to improve deep hole processing conditions, stabilize tool working conditions, and achieve high precision machining. It is not easy to chip and not easily break during production. Excellent performance such as excellent chip evacuation is an ideal choice for users. The original chip flute design is a typical feature of this tool for carbide long drills. On the one hand, the tool is made of ultra-fine grained carbide which is not easy to chip and break; on the other hand, the surface of the flute is coated. The layer is smoother and the chip removal performance is outstanding. In addition, the product's double-edged belt design, increased core thickness, high rigidity and other characteristics can make the processing conditions more stable, which is very suitable for mold hole processing with more interference holes.
