The MK-Manta III Core Drill, with Milwaukee motor will operate in either a high or low gear speed.
This speed combined with applied pressure provides the cutting action for the core bit. Speed selec-
tion and pressure are determined by hardness of material, aggregate size and grade of diamond
core bit. Generally, harder material and larger aggregates require more speed and pressure. Use low
speed for large diameter bits and high speed for small diameter bits. Changing of the speeds is ac-
complished by using the speed shift lever built into the gear case.
Specifications for the different motors are listed in the table below.
