For the last few builds I've found myself fabricating or modifying amp chassis to fit my needs. I'm now looking to invest in some quality tools specifically for making tube socket holes. I started using a step bit for everything up to 3/4" and I've used a few different brands of budget knockout punches, but they have all had shortcomings with durability or ease of use. I use Belton sockets exclusively, so only need the 1.25" punch. I'm experiencing a bit of sticker shock after seeing the price of the name brand! https://www.amazon.com/dp/B002JAUIOM/?tag=tdpri-20 Remember I'm still a DIY builder not a production shop. Now I have to ask, What do you guys use? Anyone have experience with these, and are they worth it? Is there a better option? Thanks in advance for your wisdom, experience and opinions!
