Which one of the following is a single point cutting tool?

SOLUTION

Concept:

Cutting tools may be classified according to the number of major cutting edges (points) involved as follows:

• Single point Tools (One dominant cutting edge): e.g., turning tools, shaping, cutoff/parting tool, planning and slotting tools, and boring tools
• Multiple Cutting Edge Tools (More than one cutting edge): e.g., Drill, milling cutters, broaching tools, hobs, gear shaping cutters, grinding wheel, Hacksaw Blade. 

Parting:

• Parting or cutoff is the operation of cutting a piece off by slicing a groove all the way through it with a special parting tool or cut off tool.

Hacksaw blade:

• A hacksaw is a hand tool used to cut metal.
• Its main parts are: frame, blade, handle, and adjusting wing nut.
• It has several points that cut the metal during metal cutting.

Grinding:

• Grinding is a metal cutting operation performed by means of a rotating abrasive tool, called “grinding wheel”.
• Grinding is the most common form of abrasive machining.
• It is a material cutting process that engages an abrasive tool whose cutting elements are grains of abrasive material known as grit.
• These grits perform the cutting operation multiple grits perform the cutting action.

Milling:

Milling is a process of producing flat and complex shapes with the use of a multi-point (or multi-tooth) cutting tool.
