View profile →A BTA drill head is the cutting tool used in the single-tube system: it cuts with carbide inserts or a solid-carbide head, and chips are evacuated internally through the drill tube while coolant is fed between the tube and the bore wall. It is the standard for bores from about 18 mm upward.
BTA and ejector heads cover from roughly 18 mm to 500 mm in diameter, in both solid-head (small diameters) and indexable-head (larger diameters) designs. The head type and insert style are selected to the bore size, depth and material.
Full-line suppliers (such as botek) cover the whole diameter range with matched guide pads and regrind support; specialists often lead on price and lead time for specific sizes. Verify regrind turnaround and guide-pad availability before buying, since these drive the life-cycle cost.
