We know that the carbide drillsbit can greatly improve the productivity and reduce the cost of each hole processing. CoroDrill 860 is the most rapidly cutting solid carbide drill bit in the market, mainly used for drilling of steel. The drill is well suited for conventional drilling, chamfering hole, inclined surface drilling, drilling cross hole, diamond laminated plate and concave surface borehole etc. In the aspect of hole processing performance, CoroDrill 860 is a new revolution. CoroDrill 860 bit of optimized design, can achieve much more than many of the common drill hole penetration rate and the processing safety - which means that it has the strength to improve reliability under the highest cutting parameters.

This kind of drill is specially designed for machining steel parts, which is suitable for machining of conventional drilling, chamfering, inclined surface, cross hole, pile drill and concave/convex surface. When using high cutting parameters for long or short cutting materials, this kind of carbide drill cuttings control is excellent and can achieve consistent and unfault-free drilling.

And processing all kinds of steel materials under high cutting parameters when chip control is very good, because CoroDrill 860 bit unique channel combined with a new chip groove, even under very high penetration rate can be achieved efficiently chip removal, it ensures the efficient and safe drilling.

The small features of the 860 cutting force of CoroDrill mean that the load on the cutting edge is also small, which is not easy to be problematic when the parts or thin-walled parts are poorly processed. Currently available, 3 ~ 8 times the diameter of the gage length range bit, chip can be used in long and short of scrap materials processing, such as alloy steel, low carbon steel, low alloy steel, high alloy steel and steel castings, etc. The standard diameter range is 3 ~ 20 mm, and the obtained hole tolerance is 8 ~ IT9.

Summary CoroDrill 860 solid carbide drills

The technical features of the head are as follows:

Unique new cutting edge shape can reduce cutting force and improve chip control.

The chip groove shape optimizes the chip forming, which improves the chip flow and chip removal.

The high toughness new tungsten carbideextends the cutter life;

The blade handle can control wear and provide higher reliability;

The enhanced bit round Angle improves the strength and the processing safety.

CoroDrill 860 reduces the processing cost of each hole, improves performance reliability, can achieve higher cutting parameters, and optimizes the performance of chip removal. Long tool life, wear and control.
