Forging 3 Wings Chevron Drag Bits with Tungsten Carbide Material High Strength Flat PDC Cutter


Application

3 wings chevron 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 chevron drag bits tend to drill faster and aggressive, whereas, are shorter lasting and less durable. Rotary table speed ofstep drag bits should be between 50 and 60 rpm with light to medium weight on bit (WOB), becauseharder formations, like hardpan and gravel, require more WOB.
3 wings chevron drag bits are economical tools when drilling softer geological formations and shallower depths, they are primarilydesigned formedium to hardformation and areused in areas thatcontain a lot ofrock ,such as hard shale, limestone, and tougher gravels, etc. And also chevron drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.

The diameter and thread showed as above are usual size, other sizes are available upon request.

Thread size: 2 3/8'' API Reg, 2 7/8'' API Reg, 3 1/2'' API Reg, 4 1/2'' API Reg, 6 5/8'' API Reg, 2'' API IF, 2 3/8'' API IF, 2 7/8'' API IF, A Rod, N Rod, AW, BW, NW, AWJ, BWJ, NWJ.

Characteristics

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