How Many Drills Does a Tradesman Need?

For most tradesmen a drill is an essential part of their power tool kit, and in many cases more than one type of drill is required to tackle specialist applications often encountered particularly in the construction and engineering industries. Technical Data used in the field explained in drilling courses in Islamabad.

Rotary Drills are basic and often have two speeds and a variable speed option. The ability to change speed makes the tool more flexible in terms of the types of material it is able to drill effectively. Rotary drill are commonly used to drill metal, wood, plastics and most materials where hammer action is not required.

Hammer Drills include the option to switch on hammer action making them suitable for drilling concrete and masonry. With the hammer action switched off these hammer drills can also tackle wood, metal and plastics etc making them extremely versatile with most tradesmen including a Hammer drill in their kit. Some more details of drilling courses in Islamabad are as under.

The key feature of SDS-Plus Rotary Hammer Drills & SDS-Max Rotary Hammer Drills is the use of a piston mechanism to deliver a very powerful blow to the drill bit as it rotates.This is much more powerful than a simple Hammer Drill and gives the tool the ability to create much larger and deeper holes in materials like concrete and brick. The SDS name for these tools comes from the drill bit quick release mechanism which is designed to lock the drill bit into the tool securely which is essential in view of the powerful blows being delivered to the bit by the piston mechanism.

Many SDS-Plus and SDS-Max tools include a rotary stop feature which stops the tool turning while the hammer action continues to operate. This allows the use of a wide selection of chisels suitable for various applications likely to be encountered by tradesmen involved in construction.

There is also a range of drills which are designed for specific applications including Angle Drills which are basically Rotary Drills with an angle head to allow drilling in confined spaces. Diamond Core Drills run at a specific speed and have a clutch set to allow the operator to tool with diamond cores in some cases up to 6 inch diameter.
