Typical Applications
-
General drilling in steel, cement, and power plant workshops.
-
Fabrication support work for flanges, brackets, gussets, and smaller structural members.
-
Auxiliary drilling operations in ordnance factories, defence workshops, and heavy engineering shops.
-
Workshops requiring a robust, floor-mounted drilling machine for repetitive day-to-day tasks.
Machine Description
Machine Description
- • Heavy-duty pillar drilling machine intended for rigid drilling and tapping in industrial maintenance and fabrication environments.
- • High-mass cast-iron construction (IS:210) providing rigidity and resistance to frame deflection under drilling load.
- • Case-hardened and ground alloy steel spindle, suitable for sustained drilling duty with consistent hole alignment.
- • Shot-blasted castings improve surface durability and paint adhesion in dusty shop-floor conditions.
- • Conventional belt-driven or geared spindle systems offer a practical speed range for common drilling operations.
- • Heavier models with power feed provide more consistent downward pressure for larger drill sizes, where manual feed becomes limiting.
