This document lists and describes various tools, supplies, materials and equipment used in mechanical drafting. It discusses drawing paper, masking tape, pencil sharpeners, drawing pencils in various grades, triangular scales, erasing shields, speed ballpens, sign pens, t-squares, triangles, compasses, dividers, protractors, staple guns, and drawing tables. Key tools include t-squares for drawing horizontal lines, triangles for vertical and oblique lines, compasses for circles and arcs, and protractors for measuring angles and degrees. Materials range from drawing pencils in hard, medium and soft grades to erasers, tapes and papers for drafting drawings.

EQUPMENT IN
MECHANICAL DRAFTING

2. Drawing paper
This is where we
used to draw and
sketch.

3. -This is used for fastening the drawing
paper on the drawing table or drawing
board because it does not damage the
board and it will not damage the paper
if it is removed by pulling it off.
Masking tape

4. -used to sharpen
Pencils whenever
they show sign of
dullness. Various
types and designs
are available in
the store for use.
Pencil
sharpener

5. This is used to clean the
dirt off the drawing. A
soft eraser is
advantageous in
removing smudges and
pencil marks, whereas, a
harder eraser is useful
for making changes and
correcting errors in the
drawing. Eraser

-This is one of the
most important tools
in drawing. It comes

7. Types of pencils
• Hard pencils – are used where extreme
accuracy is required especially working on
graphs, diagrams and charts.
• Medium pencils – are used for general
purpose work in drawing.
• Soft pencils – are too soft to be used in
mechanical drafting. They are very useful
for art work of various kinds.

8. Triangular
Scales
This is a tool generally used
when reproducing a drawing,
in an enlarged
form to
or reduced
regular
some
proportion. The architect’s
scale is the most commonly
used for general drawing. Its
main function is to reproduce
the measurements of an
object in full size, reduced
size, and enlarged size.

9. Erasing Shield
This tool is made up of metal with
irregular holes. It is a useful tool to
protect the rest of the drawing when
clearing up smudges, unnecessary pencil
lines and other erasures.

10. Speed Ballpen
This pen had a
square-
tipped pen could
make broad and thin
lines

11. Sign Pen
-is a specialized
instrument used by
an engineer,
architect, or drafter
to make
constant
lines of
width for
or
architectural,
engineering,
technical

12. DRAWING INSTRUMENTS
DRAWING INSTRUMENTS are
used for drawing and designing
purposes. Their quality is very
essential if you want to have good
result.

13. T-Square
It is a drawing
instrument used when
making horizontal
lines. It is also used for
guiding triangles when
drawing vertical lines.
It is made
plastic
of wood,
or the
combination of both.

14. Types of T-SQUARE
1. FIXED HEAD
head is fastenedto the blade. It is
used for ordinary work.
2. MOVABLE HEAD OR ADJUSTABLE HEAD-It has
one fixed and one adjustable head and used only
for occasional.
3. DETACHABLE HEAD OR REMOVABLE HEAD-
designed for comfort when carrying.

15. •
Triangle
It is used to
draw vertical
and oblique
line

16. Types of triangle
a. 30 degrees X 60 degrees
b. 45 degrees X 45 degrees

17. Compass
This drawing instrument is
used when drawing arcs and
circles.

18. Divider
This is a drawing instrument used
when transferring measurements,
dividing lines and arcs into the
desired number of equal parts.

19. Protractor
to determine
It is used
gradations of the degrees
arcs,
when measuring
angles and circles.

20. handheld
-a
machine used to
drive heavy metal
staples into wood,
plastic.
Gun Tacker
