2. Nibbler - Wikipedia

   en.wikipedia.org/wiki/Nibbler

   A nibbler, or nibblers, [1] is a tool for cutting sheet metal with minimal distortion. They may be used for nibbling. One type operates much like a punch and die, with a blade that moves in a linear fashion against a fixed die, removing small bits of metal and leaving a kerf approximately 6 mm (0.24 in) wide. Another type operates similar to ...

3. Drill bit - Wikipedia

   en.wikipedia.org/wiki/Drill_bit

   In metal, the brad point drill bit is confined to drilling only the thinnest and softest sheet metals, ideally with a drill press. The bits have an extremely fast cutting tool geometry: no point angle, combined with a large (considering the flat cutting edge) lip angle, causes the edges to take a very aggressive cut with relatively little point ...

4. Shear (sheet metal) - Wikipedia

   en.wikipedia.org/wiki/Shear_(sheet_metal)

   Large versions can cut sheet metal up to 12 gauge. [5] An alternative to the hand tools are hydraulically powered tools attached to heavy machinery. They are usually used to cut materials that are too bulky to be transported to a cutting facility, too big or dangerous for the hand tools and are stored at remote locations (e.g. mines, forests). [6]

5. Types of press tools - Wikipedia

   en.wikipedia.org/wiki/Types_of_press_tools

   Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the size of the die & clearance is given on punch. It is a metal cutting operation. In blanking, metal obtained after cutting is not a scrap if it is usable.

6. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   Linear cutting tools include tool bits (single-point cutting tools) and broaches. Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these ...

7. Annular cutter - Wikipedia

   en.wikipedia.org/wiki/Annular_cutter

   An annular cutter (also called a core drill, core cutter, broach cutter, trepanning drill, hole saw, or cup-type cutter) is a form of core drill used to create holes in metal. An annular cutter, named after the annulus shape , cuts only a groove at the periphery of the hole and leaves a solid core or slug at the center.

8. Broaching (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Broaching_(metalworking)

   A somewhat different design of cutting tool that can achieve the irregular hole or outer profile of a broach is called a rotary broach or wobble broach. One of the biggest advantages to this type of broaching is that it does not require a broaching machine, but instead is used on lathes, milling machines, [ 21 ] screw machines or Swiss lathes .

9. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   Milling cutters such as end mills may have cutting surfaces across their entire end surface, so that they can be drilled into the work piece (plunging). Milling cutters may also have extended cutting surfaces on their sides to allow for peripheral milling. Tools optimized for face milling tend to have only small cutters at their end corners.
