Benchtop drill press (left) and floor-standing drill press (right) A drill press is a drilling machine suitable for quick and easy drilling of straight holes, countersinking or counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand ...
The spindle speed is the rotational frequency of the spindle of the machine, measured in revolutions per minute (RPM). The preferred speed is determined by working backward from the desired surface speed (sfm or m/min) and incorporating the diameter (of workpiece or cutter). The spindle may hold the: Material (as in a Lathe chuck) Drill bit in ...
Some drill presses add a third stepped pulley to increase the number of available speeds. Modern drill presses can, however, use a variable-speed motor in conjunction with the stepped-pulley system. Medium-duty drill presses such as those used in machine shop (tool room) applications are equipped with a continuously variable transmission. This ...
In 1942, Walker-Turner released its first Radial Arm Drill Press, the RD-1170. [1] 900 Series Drill Press, Serial # 1 944.

High Speed Steel Duplex Chucking Reamer with a Straight Shank [1] Chucking reamers, or machine reamers, are the most common type of reamer used in lathes, drill presses, and screw machines that provide a smooth finish to the hole.
The percent of energy carried away in the chip increases as the speed of the cutting operation increases. This somewhat offsets the tool wear from increased cutting speeds. In fact, if not for the energy taken away in the chip increasing as cutting speed is increased; the tool would wear more quickly than is found.
