puurmasinat

Puurmasinat is the Estonian term for a drill machine, typically a drill press. It is a stationary power tool designed to bore precise holes in wood, metal, plastic and other materials by rotating a drill bit held in a chuck and advanced by a controlled feed. A drill press provides vertical alignment of the bit, consistent hole depth, and repeatable accuracy compared with handheld drills.

Construction and variants: A typical purmasinat comprises a base, a column or pillar, a movable table, a spindle with a chuck, and a feed mechanism. Variants include benchtop (compact) drills, floor-standing pillar drills, and more specialized models such as radial-arm or magnetic-base drills used for metalworking or woodworking. Speed is adjusted by belts or electronic controls to suit material and bit size.

Operation: Secure the workpiece on the table, select and install an appropriate bit, set the speed and depth stop, and feed the bit into the work with a controlled manual or automatic feed. For metal drilling, cutting fluid may be used to reduce heat and wear. The machine is designed to bore perpendicular holes with minimal operator-induced deviation.

Applications: Used in workshops, schools, and professional settings for precise drilling tasks in wood, metal and plastics, including pilot holes, through-holes, and countersinking where a consistent hole location and depth are required.

Safety: Clamp the workpiece firmly, keep hands away from the rotating bit, ensure the chuck key is removed before operation, wear eye protection, and verify bit sharpness and secure mounting of accessories. Regular maintenance helps maintain accuracy and safety.
