12 1/4'' Drag Bit Blade Bit High Drilling Speed

Product Parameters

Drag Bits Performance Overview

Drag bits are engineered from premium alloy steel and hard alloys, forged using advanced welding techniques and carefully controlled heat treatments. This combination ensures they deliver exceptional drilling speed and longevity, even under the most challenging conditions.

These bits perform best in softer formations like sand, clay, and certain soft rocks, but may struggle in more abrasive environments such as gravel or hard rock. Drag bits are commonly used in water well drilling, mining, geothermal projects, environmental studies, and exploration drilling. They are particularly effective for pilot hole drilling, generating easily loggable cuttings.

Three-wing drag bits offer faster drilling speeds, while four-wing drag bits are known for their superior durability, longer life, and ability to drill straighter holes.

Key Features of Drag Bits:

1, Built with a robust, heat-treated 4140 alloy steel body for unmatched strength and longevity.

2, CNC precision threading guarantees easy installation and consistent performance.

3, Milled forgings provide a perfect fit for carbide inserts, enhancing the efficiency of the bit.

4, Equipped with 5.5mm thick, high-quality tungsten carbide inserts for superior wear resistance.

5, Hand-ground relief behind the carbide inserts optimizes drilling performance for tougher conditions.
