Review: EGT Install Drill Bit & Tap - Worked great. Sharp Bit and Tap. Just what I needed to install my Edge CTS3 EGT Probe.
Review: Excellent for EGT drilling and thread tapping! - I purchased this along with an Auto Meter 8444 EGT gauge for my 2006 F350 6.0 Diesel. After doing A LOT of research, I used no grease and no pilot bit. I did, however, use a spring punch to establish my start point and a large N52 magnet on the drill bit shaft. I drilled very slow with minimal pressure. I paused a few times to dump the attached shaving and the bit worked flawlessly. The tap, I also used the magnet on its shaft. Afterwards I used my shop vacuum at the hole then some bent Q-tips with a small dap of grease. That worked great. Then I used copper based high temperature anti-seize on the threads before tightening the EGT thread plug. This GlowShift drill and tap set was a great product and after taking careful use of it, I guarantee I could reuse it more than once. I'm very happy with the product and I highly suggest it for EGT tapping.

### ⭐⭐⭐⭐⭐ Held up to what I needed
*by L***. on July 12, 2022*

Used this to tap cast iron exhaust manifold. Was wary about it breaking after dealing a few bad reviews, but it did just fine for me and cut threads well. I had previously never cut threads before but it worked well for a first time user! I’d say don’t crank too hard and you’ll be good to go. Just tap some, back it out, and tap some more. Maybe watch a YouTube tutorial first though.
