Tools affected include tipped tools, tool bits, and drill bits that are used with machine tools. Types of wear include: flank wear in which the portion of the tool in contact with the finished part erodes. Can be described using the Tool Life Expectancy equation. crater wear in which contact with chips erodes the rake face. This is somewhat ...
A mill-drill is similar in basic configuration to a very heavy drill press, but equipped with an X-Y table and a much larger column. They also typically use more powerful motors than a comparably sized drill press, most are muti-speed belt driven with some models having a geared head or electronic speed control.
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 ...
An automotive belt with the number "740K6" or "6K740" indicates a belt 74 inches (190 cm) in length, 6 ribs wide, with a rib pitch of 9 ⁄ 64 of an inch (3.6 mm) (a standard thickness for a K series automotive belt would be 4.5mm). A metric equivalent would be usually indicated by "6PK1880" whereby 6 refers to the number of ribs, PK refers to ...

Some drill presses and milling machines contain a simple belt-drive CVT system to control the speed of the chuck, including the Jet models J-A5816 and J-A5818. [50] In this system, the effective diameter of only the output shaft pulleys is continuously variable.
Even on many drill presses, handheld drills, and lathes, which have chucks (such as a drill chuck or collet chuck), the chuck is attached by a taper. On drills, drill presses, and milling machines , the male member is the tool shank or toolholder shank, and the female socket is integral with the spindle.
