Description

A Drilling Machine or Drill Press is one of the most common machine tools used in the workshop. Although used primarily for drilling holes, they can be used for a number of machining operations including: reaming, tapping, counterboring, countersinking, and spotfacing. In addition, attachments can be added to enable Mortising, Drum Sanding and some light duty Milling or Routing (but care must be taken not to exert too much sideways force or the chuck may become loosened by vibration)


Features and Applications

The most commonly used Drill Press for general use is a Sensitive Drilling Machine and these are suitable for most moderate-to-light duty work. They normally incorporate a belt drive spindle head via double Cone Pulleys which provide a range of speeds (electronic speed controls are also available).


The drill chuck is held usually by a Morse Taper inside a Quill which can be fed vertically via a Rack and Pinion as the spindle is rotated. Hand feeding the tool into the workpiece by this mechanism allows the operator sensitively to to "feel" the cutting action of the tool.


Sensitive Drilling Machines are available as both a Bench Drill and a floor-mounted Pedestal Drill. Both variants usually have tables which can be raised and lowered by a Rack and Pinion mechanism, and some tables can be tilted to allow drilling at an angle. It is possible also to mount a Power Drill in a stand to provide some of the advantages of a Drill Press


Radial Arm Drilling Machine These are specially useful on larger and heavier parts which may be difficult to position easily, because the the spindle can be positioned directly over the workpiece rather than needing to move the workpiece. The Radial Arm Drilling Machine can often be coupled with a tilting table, or a trunnion table, to drill intersecting and angular holes.


DT Online Buyers' Guide
  • Stands for Portable Power Drills are inexpensive and adequate if only light work mainly in wood and plastics is intended.
  • For more general purpose home workshop use choose a bench drill.
  • The floor-mounted drill shown is for more arduous use drilling larger diameters.
  • A combined Milling/Drilling machine would be a popular choice for Model Engineers and in home workshops.
  • Mortisers comprise an Auger Bit inside a hollow square chisel which squares off the hole as it is drilled (Mortising attachments for Drill Presses are also available)
  • Mini-drills and PCB Drills are useful for modelling and for drilling holes in circuit boards to receive eletronics components.
