This document discusses drilling machines and their functions and safe operation. It describes different types of drilling machines from handheld power drills to bench-mounted and floor-mounted models. Drilling machines are used to cut holes in materials like metal, wood, and others. The document provides instructions on selecting and using drills properly and safely, including always wearing eye protection, securing the workpiece, and keeping hands clear of drill bits. Safety procedures are emphasized to prevent accidents and loss of time or materials.

3. MEANINGS
AND
FUNCTION
 A drilling machines comes in many
shapes and sizes, from small hand-
held power drills to bench mounted
and finally floor-mounted models.
 Can perform operations other than
drilling, such as
countersinking, counterboring, reami
ng, and tapping large or small holes.
 The size or capacity of the drilling
machine is usually determined by the
largest piece of stock that can be
center-drilled.
 Used to cut holes into or through
metal, wood or other materials.

11.  Always wear eye protection when using any drill machines.
 Wear an apron to protect clothing from oil or dirt
 Always anchor the base of the drill press securely to the floor before starting
any project.
 Secure the item being drilled.
 Keep your hands clear of the drill bit.
 Keep your workshop free of distraction.

13.  Do not support the workplaces by
hand. Use a holding device to prevent
the workpiece from being tom from
the operator’s hand.
 Never make any adjustments while
the machine is operating.
 Never clean away chips with your
hand. Use a brush.
 Keep all loose clothing away from
turning tools.
 Make sure that the cutting tools are
running straight before starting the
operation.
Following safety
procedures during drilling
operations will help
eliminate :
• Accidents
• Loss of time and
materials.

15. Drilling machine or drilling installation which can be
moved or positioned in relation to the material as profile
steel and plate with the use of a location measuring
system for the material to be drilled and with the
preferable use of cutters as a drilling tool which lead to a
quicker and cheaper drilling-process and which gives
also the possibility to combine the drilling installation
with other machines or installations for sawing, cutting
and blasting of profile steel and plate on an easy and
profitable way.
