View profile →UNISIG designs and manufactures precision deep hole drilling machines, gundrilling machines, BTA machines, tools and automation systems in the USA — from sub-millimeter medical drilling to 500 mm diameter holes over 10 meters deep.
View profile →WIDMA, the machine tool division of Kennametal India, is a deep hole drilling machine manufacturer in India offering gundrilling, BTA drilling, counter boring, skiving and roller burnishing machines with drilling depths up to 3,000 mm.
View profile →A BTA machine uses the single-tube system (STS): coolant is fed between the drill head and the bore wall while chips are evacuated through the inside of the drill tube. It is the standard choice for large-diameter deep bores with high depth-to-diameter ratios.
BTA drilling typically covers bores from about 18 mm up to several hundred millimetres in diameter, with depth-to-diameter ratios of 50:1 and beyond in many production applications.
Verify manufacturing capability (an in-house factory rather than a trader), certified quality systems such as ISO 9001 and CE, machine rigidity and guide-bushing design, and the supplier’s track record on your specific material and depth range.
