This is a tool with a rotating drill bit used for drilling holes in various materials. Drills are commonly used in woodwork and metalwork. The drill bit is gripped by a chuck at one end of the drill, and is pressed against the target material and rotated at speed. The tip of the drill bit does the work of cutting into the target material, slicing off thin shavings (twist drills or auger bits) or grinding off small particles (oil drilling).

 

Types Of Drills:

 

Hammer Drill: This is similar to a standard electric drill, with the exception that it is provided with a powerful hammer action for drilling masonry. The hammer action may be engaged or disengaged as required.

 

Rotary Hammer Drill: This is an electric drill type dedicated to drilling holes in masonry. This percussion drill uses a weight to create the impact force on the masonry bit. Generally, the drill chuck of this drill is designed to hold SDS drill bits.

 

Cordless Drills: A cordless drill is a type of electric drill, which uses rechargeable batteries. These drills are available with similar features to an electric drill.

 

Drill Press: This is a fixed style of drill, which may be mounted on a stand or bolted to the floor or workbench. It consists of a base, column (or pillar), table, spindle (or quill) and drill head, usually driven by an induction motor. The head has a set of handles (usually 3) radiating from a central hub which, when turned, move the drill spindle (and chuck) vertically, parallel to the axis of the column.

 

Geared Head Drill: This is identical to the drill press in most respects, however they are generally of sturdier construction and often have a power feed installed on the quill mechanism, and safety interlocks to disengage the feed on over travel.

 

Radial Arm Drill: This is a geared head drill that can be moved away from its column along an arm that radiates from the column. These drills are used for larger work; the arm can swivel around the column so that any point on the surface of the table can be reached without moving the work piece.

 

Mill Drill: This is a combination milling/drilling machine. This is the latest and one of the best utility Drills available in the stores.
