Bar Peeling Inserts Carbide Tool Inserts GY7650 GY7659 High Hardness Steel

Bar peeling inserts are mainly designed for peeling and finishing of steel bars and tubes. Square shaped peeling inserts with four cutting edges can be used for finishing process; triangle shaped peeling inserts are mainly applied in products with limited requirements on surface roughness, also it is more extensively used together with the square shaped peeling inserts in rough finish; round inserts are commonly used along with the square and triangle inserts in rough finish.

We provide suitable grade and coating according to hardness of steel

• High Hardness Steel GY7650 and GY7659

The hardness range of machined material is 260-340HB. GY76, combined with thick CVD coating (batch No.50 or 59) shows super wear resistance, tenacity, red hardness and impact resistance.

• Medium Hardness Steel GY7550 and GY7559

The hardness range of machined material is 185-270HB, GY7850 and GY7859 with CVD coating demonstrates high tenacity and better impact resistance. It is suitable for heavy duty machining and interrupted cutting.

• General Hardness Steel GY7850 and GY7859

The hardness range of machined material is 140-210HB, GY7850 and GY7859 with CVD coating can impressively improve wear resistance, tenacity and demonstrate better impact resistance.
