Spiral surface spiral drill

Spiral drills with a smooth and hard surface can reduce friction, wear, and power requirements, and are commonly used in screw conveyors for transporting bulk materials. The scraper is formed into a continuous integral helical surface spiral drill through cold rolling.

Combination spiral drill

The combination spiral drill can solve the heavy load requirements in applications that require thicker outer diameter scrapers, thereby extending the wear period. The combination scraper is assembled, welded, and installed in complete circular segments.
