Description

SUPER Drill Steel has high fatigue strength, toughness and offers high wear resistance giving an efficient and economic

drilling operation. The unique wear resistant carbide grade in our integral drill steel, in combination with the generous

carbide volume, provides extended service life in all applications. Our unique R23 rods and bits for extension drilling

provide the strongest thread in hole sizes 33– 45 mm. For the most aggressive applications we have fully carburized

rods with superior wear resistance and service life. In fact worKing with Sandvik means that you can expect consistent

high quality and maximum operational dependability when it comes to all small hole drilling applications. 64mm T38 thread drill button bits

Underground long-hole Drilling tools mvehicle for mining tools mainly equipped with guide rail type pneumatic rock drill, and a full hydraulic drill rig truck for underground mine,long-hole blasting holes, and a retaining hole drilling. T38 thread drill button bits diameter including 64mm,76mm,89mm,102mm. we also can provide standard and retrac skirt including cross bits, button bits etc.

King Kong's Tungsten carbide inserts are same as Sandvik YG05 sizes. and we also use the same technology as Sandvik including the steel materials and Heat treatment.

_{Button bits should be reground when penetrati on rat es drop or if the cemented carbide shows signs of damage

Fixed grinding routines often result in good working practices.

Bits for instance, can be examined and then reground after a specific number of holes, or at the end of the shift. Premature grinding is not necessarily uneconomical since less carbide needs to be ground off. It is better to regrind rather than reducing productivity due to damage.

Correct grinding adds considerably to drill bit service life. But equally important, it also enhances the performance of the entire drilling operation, especially hole straightness.}

T38 thread in same as the International thread and can be used for Sandvik, Atlas copco, Furukawa,Ingersoll-Rand and Montabert etc.

All bit diameters are larger than the given dimensions in the catalog
Cross bits: Can be a maximum of +1mm due to manufacturing tolerance
Button bits: Some bit designs can be a maximum +3mm to compensate for
fast diameter wear.Related Products
