Sandvik HL1560ST is a hydraulic top hammer rock drill designed for large-diameter longhole drilling in DL411 and DL421 underground longhole drills. Its simple yet robust construction reduces wear while optimizing drilling performance.

Features

Heavy-duty rock drill

The strong modular construction has only two moving parts: the piston and distributor sleeve. The drill body is made of three modules joined by short side bolts, which keeps the number of joint faces and contact surfaces low, increasing drill lifetime and quality.
Manual or automatic join opening

Utilize the optional power extractor to be able to automatically or manually open rock tool joints when using one-hole or fan automation.
Meet rotation requirements easily

Includes two rotation motor variants to meet torque and RPM requirements for rotation in the application range of HL1560ST.
