What to Look for When Buying a Used TechniDrill
Inspect the spindle and drill slide. Check spindle runout at the tool collet and listen for bearing noise after warm-up. Verify the drill slide moves smoothly across its full stroke on the linear guideways. Hesitation, chatter, or uneven travel points to guideway wear or ballscrew issues. On two-speed gearbox machines (such as the 2.00-30-48), test both ranges under load. Counter-rotating fixtures with pneumatic chucks should clamp repeatably and release cleanly.
Evaluate the high-pressure coolant system. TechniDrill machines run coolant up to 2,500 psi (172 bar) at flow rates up to 160 gpm. Inspect the pump, pressure gauges, filter canisters, and heat exchanger. Check for leaks at fittings and the rotating coolant induction joint. The twin tank system (clean and dirty) should be free of heavy sludge.
Verify the control platform and fixturing. Current TechniDrill machines use an embedded PC-based control running Windows with EtherCat communication. Boot the control, cycle through the HMI screens, and test G-code programs on multi-axis units. Older machines shipped with Allen Bradley PLC hardware (often the SLC-500). Confirm the fixturing package: 6-jaw chuck, 3-jaw tailstock, knee-type table, rotary table, or auxiliary CAT 40 milling spindle.
TechniDrill Machine Series
Single-Spindle Gundrilling Machines
The 2.00-30-48 is the flagship single-spindle unit: 2-inch (50.8 mm) capacity, 48-inch (1,219 mm) depth, 30 HP AC spindle motor, and a two-speed gearbox. Smaller single-spindle machines are available in 0.75-inch and 1.25-inch configurations. All feature heavy-duty bases with linear guideway construction, full enclosures, and embedded PC controls.
Multi-Spindle Gundrilling Machines
TechniDrill multi-spindle machines target high-volume production. The 500-12-24-4 (half-inch diameter, 24-inch stroke, four spindles, 3 HP per spindle) is typical. Multi-spindle units are commonly specified for automotive camshafts, firearms barrels, drive shafts, and scroll compressor components. Auto-loading options and servo-positioned slides increase throughput on long runs.
Multi-Axis CNC Gundrilling Machines
The Multi-Axis line provides CNC-controlled motion for complex hole patterns in heat exchangers, injection molds, and hydraulic manifolds. The 0.75-inch and 1.25-inch capacity machines use a knee-style fixture table for X and Y movement. The 2-inch capacity machine uses a traveling-column design with a rotary fixture table plus an auxiliary CAT 40 milling and tapping spindle.
BTA/STS Deep Hole Drilling Machines
The BTA/STS series addresses large-diameter deep hole drilling for aerospace, oil country tubular goods, and heavy industrial applications. The TBTA series includes the TBTA-3A-6, a three-axis BTA machine that drills a 6-inch (152 mm) diameter hole from solid in a single pass. Larger capacities reach 10 inches (254 mm). BTA/STS drilling uses a tube-style drill where coolant flows outside the tube and chips evacuate through it, enabling deeper holes with excellent straightness.

Frequently Asked Questions About Used TechniDrill Machines
Is TechniDrill still in business?
Yes. TechniDrill was founded in Kent, Ohio in 1984 and acquired by Kays Engineering in 2020. New machines are built-to-order at the Kays facility in Marshall, Missouri, alongside the DeHoff and Eldorado brands. Parts and service for legacy machines are also supported.
Can I still get parts for a used TechniDrill?
Yes. Kays Engineering provides parts, service, and technical support for all existing TechniDrill machines, including units built in Kent, Ohio before the 2020 acquisition.
What is the difference between gundrilling and BTA/STS drilling?
Gundrilling uses a single-flute drill with coolant supplied through the drill and chips evacuated externally along a V-groove, ideal for diameters up to about 2 inches. BTA/STS uses a tube-style drill with coolant supplied externally and chips evacuated through the tube, enabling diameters up to 10 inches and excellent straightness at extreme depths.
What CNC control does TechniDrill use?
Current machines use an embedded PC-based control running Windows with EtherCat communication. Multi-axis units support full G-code programming. Older machines shipped with Allen Bradley PLC controls (SLC-500 series).
What industries use TechniDrill machines?
Aerospace, firearms and defense, oil and gas, automotive, medical device manufacturing, heat exchanger fabrication, and injection mold cooling channels.
What TechniDrill models hold their value best?
Multi-spindle production gundrillers (500-series four-spindle machines), the 2.00-30-48, multi-axis CNC machines, and TBTA-series BTA machines all hold strong resale value. Windows-based PC control units typically command a premium over Allen Bradley legacy units. Call (844) 478-8181 for current valuations.
