Chisel Bit Integral Rod Integral Steel Drill Rod H19 Integral Drill Rod

Integral Drill Steels are a fixed length with a shank at one end and a bit at the other ,and are able to drill to a depth equivalent to their effective length.The bit may consist of single chisel shaped tungsten carbide insert or three such inserts.
To drill deep holes,the rods are designed to be used in a series where the lengh of any rod used in longer than the one used just before it.
To do this ,a series of rods must be produced so that the bit diameter is reduced for each increase in lengh if rod to prevent jamming of the bit in the hole.
The products in this brochure are the most cmmonly used.For other bit diameters and lengths.
