BTA deep hole drill head system,CoroDrill,drilling tool

This BTA drill head adopt imported indexable coating blade, it has the advantage of high efficiency, change blade easily, long service life, low using cost. And it can drill on carbon steel, high strength alloy steel, stainless steel and so on.

In deep hole drilling, a combination of tool design and cutting fluid pressure are used to flush the chips out of the hole. Both the STS and Ejector drill system can produce holes with excellent surface finish, close dimensional tolerance and concentricity.

--Customer specified diameters
--Lasermarking of code, dimension and tube range
--Excellent chip control in both low and high feeds
--Few inserts and support pad sizes cover the whole diameter range
--Modern grade and geometry programme cover most workpiece materials
-- Botek ejector drill heads are available in diameter ranges from 18.4 mm- ~200 mm.

The Ejector or double tube system is a derivative of the BTA drilling system. Ejector drilling is adaptable to conventional machinery such as machining and turning centers. The Ejector System procedure allows depth to diameter ratios up to 100x's diameter.

The coolant is supplied at the spindle through a special coolant inducer. Pressurized coolant flows through the annular space between the inner and outer drill tube supplying the drill head. The coolant flows over the drill head providing lubrication and chip evacuation through the inner tube.
