It is best of drilling operation in metallic components with high precision. It has fixed base, a worktable and a spindle on the top. Its worktable and spindle can move up and down on its smooth and vertical pillar. It is handy to perform its application in engineering and industrial tool rooms. These run through V Belts.
Pathak Radial Drilling machine are of robust construction and are designed for heavy duty drilling. All cast parts are of fine close grained grey iron, machined to closed tolerance and are subjected to rigid inspection at all stage of assembly to ensure accuracy and trouble free service. Each and every machine is thoroughly checked and tested to grade-1 standard.
