25
Q

Four factors to be considered when selecting a twist drill.

A

1 Diameter of the drill
2 Length of the twist drill
3 Type of cutting tip
4 Material to be drilled

26
Q

Uses in the motor industry include: bumpers, grills and wheels.

A

Chromium

27
Q

Explain why the trailing edge of the twist drill lip must be lower than
the leading edge.

A

To provide clearance for the cutting edge

28
Q

It is easily shaped and welded, it is soft and ductile.

A

Mild steel

29
Q

List three reasons why cutting fluid is used when drilling.

A

Acts as a coolant
Acts as a lubricant
Will improve the cutting finish

30
Q

It is very versatile, diffrent combinations of zinc and copper produce brass with different characteristics

A

Brass

31
Q

Explain why it is important to refer to the manufacturer’s charts when
drilling a hole for tapping

A

Manufacturers provide tap and drill size charts to enable technicians to
select the appropriate drill size to form the tapping hole and the appropriate
tap to form the thread

32
Q

Uses in the motor industry include: body panels and parts that are not load bearing.

A

Mild steel

33
Q

Describe the procedure involved when sharpening a twist drill.

A

Install a fine grade wheel on the grinder.
Switch on the grinding wheel.
Holding the drill bit firmly, place the drill bit against the tool rest at the correct
angle.
Applying light pressure offer the drill bit cutting edge to the grinding wheel.
Twist the drill bit to form the cutting edge clearance.
Repeat this procedure for the second cutting edge.
Cool the bit and check both cutting edge angles on a drill angle gauge.

34
Q

It is relatively light but strong. It is also cheap to manufacture.

A

High tensile steel

35
Q

List three outcomes that should be avoided when drilling a hole.

A 
A rough hole
An oversize bore
A split drill web
Damaged corners
Drill breakage
36
Q

Uses in the motor industry include: chassis rails, front and rear impacts bars and body panels

A

High tensile steel

37
Q

State a safety precaution that must be observed when using drilling
equipment to protect tools and equipment.

A

Inspect tools prior to use – leads, plugs, drill body, drill bit
Use a RCD
Use tools correctly
Select the correct drill bit for the task
Always use the guards provided
Check that the machine is securely mounted
Check the condition of the guards
Adjust the machine correctly prior to use
Only drill suitable materials
Use correct drilling speeds
Use appropriate cutting fluid
Clean the machine after use

38
Q

It is relatively hard and strong.

A

Spring steel

39
Q

Taps

A

is designed to cut internal threads into a hole in metal objects,
allowing bolts or studs to be fitted.

40
Q

Uses in the motor industry include: coil and leaf springs.

A

Spring steel

41
Q

Dies

A

A die is designed to cut external threads

42
Q

Its rust resistant and hard wearing.

A

Stainless steel

43
Q

Thread files

A

A thread file is used to repair an external thread.

44
Q

Uses in the motor industry include: exhaust system components and some body parts.

A

Stainless steel

45
Q

Sleeve
thread
inserts

A

A thread insert is used when there is not enough material around the
hole or when a specific thread is required.

46
Q

Its very ridged and strong in compression. Cast into intricate shapes and forms a good wearing surface.

A

Cast iron

47
Q

Outline the procedure involved when cutting a thread in a blind hole
using taps.

A

Step 1 Consult with the manufacturer’s tapping and drilling chart and
select the appropriate drill bit and tap.
Step 2 Drill the tapping hole.
Step 3 Using the taper tap and carry out steps 3 - 6 as above. Do not
force the taper tap at the bottom of the hole as the tap may
break off.
Step 4 Remove the taper tap and clean out the hole.
Step 5 Install the intermediate tap and repeat steps 3 – 4.
Step 6 Install the bottoming tap and repeat steps 3 – 4.

48
Q

Uses in the motor industry include: cylinder blocks, cylinder heads and other housing.

A

Cast iron

49
Q

Outline the procedure involved when installing a thread insert.

A
  1. Select a thread insert kit to suit the thread diameter and pitch
    required.
  2. Select the correct drill bit from the kit.
  3. Drill out the original thread.
  4. Select the appropriate tap.
  5. Tap the new thread.
  6. Fit the Heli-coil onto the installation tool supplied in the kit ensuring
    that the tang on the Heli-coil is firmly inserted into the slot of the
    installation tool.
  7. Screw in the Heli-coil into the tapped hole. This reduces the diameter
    of the Heli-coil allowing it to be threaded into place.
  8. When the Heli-coil is in place, break off the tang.
50
Q

Its strong and can be forged.

A

Medium carbon steel
