Available at Auction The 1998 TechniDrill Model 300-140 7.240 144-1 Series BTA Single Spindle Ejector Gun Drill is a heavy-duty deep hole drilling machine purpose-built for oilfield, aerospace, and industrial long-bore production, with a BTA drilling range of 1 to 7.240 inches, an ejector drilling range of 1.250 to 7.240 inches, 9.5 inch counter-bore capacity, and a 144 inch drilling stroke supported by two whip guides. Powered by a 100 HP main spindle at 100-900 RPM and a 30 HP counter-rotating spindle at 60-120 RPM, the machine is fed by a 1,600 gallon Rexroth coolant system with 10 micron filtration, 30 and 40 HP pump motors delivering 160 GPM at 800 PSI, SLC 500 PLC control with Panelmate Power Pro display, remote operator's console, and double tube ejector for reliable, repeatable deep hole production. Compared to earlier single-spindle BTA drilling platforms like TechniDrill's 200 series and older gun drill generations, the 300-140 expands drilling stroke and coolant system capacity significantly, enabling full 144 inch uninterrupted bores at 7.240 inch diameter with counter-rotation for improved chip evacuation and bore straightness. The Panelmate Power Pro interface also upgrades operator diagnostics and recipe control over the hardwired panels used on the preceding generation of BTA gun drills.
