TEC 3/8-in. HEX Shank Drill Bit

There’s nothing exciting about drill bits. I’d rather watch mastic dry instead of talking about a drill bit. Until now. Why? The folks at The Energy Conservatory (TEC) have created a drill bit worth talking about.

If you’re a High-performance HVAC guy or gal, this drill bit is for you. Meet the TEC 3/8-in. hex drill bit, a little guy built for HVAC professionals who test, measure, and don’t have time to baby their tools. This isn’t your average grab-it-out-of-the-bin drill bit.

It’s designed specifically for installing a nice, clean testing port for testing HVAC system static pressures to take temperature measurements. The magic is in the details. The milled drill stop leaves only 5/16-in. depth — just enough to punch through the metal skin without hearing that surprising hissing noise issuing from the coil, or getting the shock of your life because you drilled through something electrical.

If you’ve ever let the genie out of that bottle you’ll appreciate this test port installation tool. The TEC 3/8-in. hex shank drill bit is laid out with a ¼-in. quick-change hex shank so you can pop it onto your drill or driver faster than a tech can grab a free doughnut at a training class. No slipping, no wobbling — just clean, confident, test port installations every time.

If precision, protection, and performance are your thing, grab one or even get 10 TEC 3/8-in. hex drill bits. In HVAC testing, accuracy matters and this little guy makes sure your drill doesn’t go rogue.

Just go to the TruTech Tools website and order yours today. It even comes with 25-hole plugs!
