Core Drill

From DT Online



Core Drills are similar in appearance to Holesaws but they are use principally to make large holes in masonry (e.g. to enable plumbing and other services to pass through the walls of a building).

Features and Uses

The cutting edges are either made of Tungsten Carbide or are Diamond coated. They can be used with a Power Drill.

Safety Point! Their large diameter can result in considerable Torque being transmitted, therefore any Power Drill used must have a clutch that will slip if it grabs. This is to avoid personal injury if the drill is twisted out of the operator's hand

Larger and longer Core Drills are used industrially for mineral exploration. For this purpose, it is the core of material which the drill removes which is of interest for analysis, rather than the hole it creates.
