2. Benjamin Forstner - Wikipedia

   en.wikipedia.org/wiki/Benjamin_Forstner

   In 1886, Forstner patented the Forstner bit. [1] The bit was revolutionary as it did not feature the lead screw (which Forstner called the "gimlet-point") or the cutting lips of more conventional wood boring bits, [clarify] and thus proved especially useful to gunsmiths and high-end woodworkers. The bit was unsurpassed in drilling a smooth ...

3. Drill bit - Wikipedia

   en.wikipedia.org/wiki/Drill_bit

   A Forstner bit could bore the mounting hole for the hinge, but particle board and MDF are very abrasive materials, and steel cutting edges soon wear. A tungsten carbide cutter is needed, but the complex shape of a forstner bit is difficult to manufacture in carbide, so this special drill bit with a simpler shape is commonly used. It has cutting ...

4. Drill bit sizes - Wikipedia

   en.wikipedia.org/wiki/Drill_bit_sizes

   One aspect of this method of sizing is that the size increment between drill bits becomes larger as bit sizes get smaller: 100% for the step from 1/64 to 1/32, but a much smaller percentage between 1 47/64 and 1 3/4. Drill bit sizes are written as irreducible fractions. So, instead of 78/64 inch, or 1 14/64 inch, the size is noted as 1 7/32 inch.

6. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
