Khalsa Oilfield Equipment provides a variety of drag bits for many types of projects in sizes ranging from 3” to 9” Our tools are made from 4140 grade alloy steel for dependable services. Each bit is machined from a forging to exacting standards and then tipped with suitable grade tungsten carbide for long life. Our drag bits range from step bits, for soft and medium formations, to chevron style bits for harder formations.

Features of Our Carbide Insert Drag Bits
   
Behind carbide inserts relief is hand ground for maximum performance.
Carbide inserts are individually BRAZED using 50% nickel silver rod.
Bits we fabricate are welded with high tensile strength 7018 rod.
Our blades originate from 4140 heat-treated steel forgings.
Forgings are milled to better seat the carbide inserts.
Select grade tungsten Carbide inserts 3/16” thick are used.
Bits can be built to the gauge tolerances required.
