Core Cutting and Drilling Machine

Product Description

Core Cutting/Drilling Machine :

Introduction

Often, existing concrete structures will need to be examined and tested to ensure the concrete remains of adequate strength and durability. This test is used to determine the compressive strength of a concrete core, which has usually been extracted from an existing structure. The value of compressive strength can then be used in conjunction with other measured properties to assess the condition of the concrete.

Extraction of concrete cores, achieved by rotary drilling using a diamond tipped hollow barrel, serve as a means of taking a sample of concrete which can then be used to determine various physical properties, but most commonly compressive strength.
Cores can generally be extracted from wherever access allows, and would include floor slabs, walls and columns. 10cm diameter cores, generally afford the minimum diameter required for a representative sample and require less reinstatement than larger diameter cores. 15cm diameter cores will generally give more representative samples than smaller diameters but require more reinstatement.

Specification

The Core Drilling Machine is Diesel Engine  operated powered road building drill has been designed specifically for the purpose of drilling test cores from or holes in Roads, Airport Runways, Bridges etc. The Machine comprises of two vertical support columns, which carry the drill head/ engine assembly accurately with the help of screwed spindle. The 5 Hp diesel engines with pulley mechanism works with minimum vibrations. The double precision bit advances with screwed spindle, which provides a constant, accurate drill pressure, minimum core chipping & long bit life. The complete assembly is supplied on a rigid metal base with levelling facility and is suitable for vertically down coring applications only. For asphalt pavement/Concrete Road. Engine driven Air cooled. Cut up to 100 mm dia specimen with impregnated diamond core bit. Extension core barrel and adaptor. Water tank also supplied with machine & spray arrangement for cooling the diamond bit.

SPARES:
