Manufacturer data; TIBO product page, brochure and trade-fair flyer. The B160 torque is given as 5,390 Nm on the product page and 4,000 Nm in the trade-fair flyer. According to the product page, BTA solid drilling starts at Ø 18 mm; the 2024 brochure gives the B series as solid drilling Ø 12.5–300 mm, counter-boring to Ø 500 mm and 1–4 spindles. Depths beyond 12,000 mm are a special configuration at the customer's request.

Frequently asked questions
What is the smallest diameter a BTA machine drills?
According to the product page, BTA solid drilling starts at Ø 18 mm; for the B80, Ø 10–80 mm is given when the gundrilling kit is used. Gundrilling machines (Ø 2–40 mm) are used for smaller diameters.
Can holes deeper than 12 metres be drilled?
The maximum drilling depth of the standard sizes is 12,000 mm (B80: 4,500 mm). TIBO states depths beyond 12,000 mm as a special configuration at the customer's request.
Can the bore be finished on the same machine?
Yes; depending on configuration and accessories, skiving and roller burnishing (in double or triple combination on cylinder tubes), pull boring, bottle boring and trepanning are done on the same machine.
