    • Draw Filing: Parallel to component axis

    Striking Tools

    • Cross-peen hammer
    • Claw hammer: For striking and pulling nails
    • Mallet: For striking chisels on wooden components (hardwood or rubber); round or rectangular

    Drilling Machine

    • Drilling: Makes, enlarges holes in workpieces using a rotating drill
      • Sharp drill edges remove material in circular layers
      • Removed metal chips escape via helical drill grooves.
    • Drilling Machine: Power-operated machine tool

    • Ceramic
    • Diamond

    Drilling Machine Operations

    • Drilling
    • Reaming (sizing/finishing a previously drilled hole)
    • Boring (enlarging a hole utilizing an adjustable cutting tool with only one cutting edge; used when a suitable drill size is not available)
    • Counterboring (enlarges the end of a hole cylindrically, forming a square shoulder with the original hole)
    • Countersinking (creates a cone-shaped enlargement on the end of a hole to accept a flat-head screw)
    • Spot facing (machining a flat circular surface around a hole, creating a seat for bolt heads, nuts, or washers; spot face cutter similar to a counterbore, but with teeth only on the end)
    • Tapping (creates threads in a metal using special tools)

    Drilling Operation

    • Drilling is enlarging/creating holes in a workpiece using a rotating drill tool.

    Reaming

    • Reaming is sizing and finishing a hole that has previously been drilled.
    • Reaming tools have multiple cutting edges.

    Boring

    • Boring is enlarging a hole using an adjustable cutting tool with a single cutting edge.
    • Used when a suitable drill size is not available

    Counterboring

    • Counterboring enlarges the end of a hole cylindrically, forming a square shoulder with the original hole. This is done with a counterbore.

    Countersinking

    • Countersinking creates a cone-shaped enlargement on the end of a hole to accept a flat-head screw. This is done with a countersink.

    Spotfacing

    • Spotfacing is machining a flat circular surface around a hole, creating a seat for bolt heads, nuts, or washers
    • Spot face cutter is similar to a counterbore, but has teeth only on the end.

    Tapping

    • Tapping creates threads in a metal using special tools.

    Tap & Tap Wrench

    • Tools for creating threads

    Exercise 2: Step Fitting & Drilling Job

    • Interpret a part drawing and fabricate it from the provided aluminum plate
    • Appropriate fitting tools and drilling are needed.
    • Sample part dimensions provided (in mm)
