YK 3 or 4 Wings Blades Pdc Drag Bit Step Drilling Tools for Hard Rock Mining

3 wings step drag bits are one piece construction of alloy steel cast with tungsten carbide cutting tips and gauge sides to ensure longer life. It has 3 wings and 3 flushing holes. Compared with 4 wings, 3 wings step drag bits tend to drill faster and aggressive, whereas, are shorter lasting and less durable.3 wings step style drag bits will produce larger cuttings force than chevron style drag bit. Rotary table speed of step drag bits should be between 60 and 80 rpm with light weight on bit (WOB).

3 wings step drag bits are economical tools when drilling softer geological formations and shallower depths, they are
primarily designed for soft tomedium formations, such as Clay, Loam, Silt ,Mostsoft-to-medium soilsthat have some moisture, etc.And also

Features
• A solid one piece heat treated, 4140 alloy steel body for bit strength & durability;
• CNC threaded machining for proper installation &use;
• Forgings are milled to better seat the carbide inserts.
• Select tungsten carbide inserts 5.5mm thick are standard.
• Relief is hand ground behind carbide inserts for maximum performance.

Applications
Step drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.

3wings step drag bit advantage.
Copper brazing tungsten carbide , welding technology: Advanced technology---We process our bit with Copper brazing welding which
ensures the best hardness and avoids alloy flakes falling.

3wings step drag bit.
Body and wings intergrated:which ensures that the wings does not break during working, even in hard rock formations.
