Drill Machine – Types of Drills, Applications of Drill Machines

Drill Machine

Drill is a machine tool used for drilling the holes in solid materials like metal and wood with drill bit or driver bit. Drills are used in wide range of applications in metalworking, constructions and woodworking industries. The small drill is used for our household requirements to make holes on wall and materials. These are available in various sizes and power capacities. Drill is one of the oldest handy tools used from very beginning of the industrial era.

Types of Drills

Varieties of drills are manufactured as per the industrial needs. They are categorized based on different parameters like manual drills and automatic drill machines. Manual drills are referred as hand powdered drills used with hand pressure on the device/material to drill a hole. Manual drill variants are Bow drill, Gimlet, Breast drill and push drill etc. These are powered with electricity or compressed air known as electronic drill and pneumatic drill respectively. Drilling work is carried out at different locations with various types of drills including construction drill, wells drill, thermal drill etc. All drills have different applications of drilling from small to bigger size hole.

Pistol grip drill is commonly used in our daily work. Right angle drill is used in plumbing and electrical works. Hammer drill is similar to electrical drill with addition of hammer action on the same device. Rotary hammer drill is equipped with rotation mechanism used for drilling in solid constructions. Cordless drills with inbuilt rechargeable battery power are used where electrical supply is not reachable for drilling. Cordless drills consume high power. Thus need more spare batteries on charge during the drilling work to replace effectively on discharge of installed batteries.

Drill Press/Pillar Drill Machine

Drill press is the drill machine that can be stand mounted or fixed with floor or workbench through bolting. Drill press also known as pillar drill consist base, column, table, drill head and spindle. This bench drill use induction motor supply to execute the drilling operation faster with small or bigger drill bit. Drill press is quite lighter and efficient for operator compare to hand drill. The clamping of drill press makes the convenient positioning for precision and accurate drilling operation.

Radial Drill Machine

Radial drill machine with geared head put up press on large area without repositioning the work piece. Radial arm drill press is manufactured with several dimensions of drill head and varying base plate. Different thickness and size of drill bits are used here to drill from small to large size holes. These are very much popular and widely used in automotive, workshops and garages.

Drilling cum Milling Machine

Drilling cum milling machine is used for both drilling and milling operation. This lighter machine is having great option of milling capabilities to save the space including the added functionalities of shaping the materials.

Applications of Drill Machines

The basic function of drill machine is to create hole of different size in solid materials. Different drills are used for industry specific applications. Drill rigs are used to drill water wells and oil wells. Hand drills are used for screwing and fastening. Electrical pistol grip drill is used in common masonry works by builders, electricians and plumbers. Hammer drill is specifically used by carpenters to drill and fix the wooden parts. Cordless drills are useful where electrical supply is not possible to get for drilling. Pillar drill machine (also referred as drill press) is used in commercial applications where it required bulk production of drilled materials in various size and shape like metal sheets, plastic, wood, glass and concrete construction applications. The induction based power supply is easily controlled in drill press to increase or decrease the drilling speed and capacity. The capacity of drill press differs with pillar diameter, spindle nose, spindle travel, spindle speed and electronic motor used in the machine. These are widely used in automobile, printing and engineering field to increase the durability and tensile strength of the machine with effective execution to the resistive materials with quality performance. Milling cum drilling machine is broadly adopted in the industries where required mixing and grinding of solid and liquid substances.
