Our step bits are great for drilling a bunch of different hole sizes, but you do have to drill for a while because you're making a bunch of holes, larger and larger. These new Tungsten Carbide tipped hole saws make fast work through stainless. The only downside is that you need a different bit for every hole size. If you are going to drill several holes of the same size, you'll appreciate the speed and durability of these types of bits.
This 35mm bit is also equivalent to 1-3/8" which is appropriate for installing our ETC4S element install kit. You'll need a slow speed, high torque drill motor for these with a 1/2" or larger chuck. We have other sizes as well.
It is highly recommended that you start ANY size hole with
a smaller pilot bit approximately 1/8" and drill a couple test holes in scrap metal to get the hang of using these bits.
NOTE: These bits are recommended for users that have a reasonable/intermediate level of DIY experience with power tools and/or metal working in general. Keep in mind that when the larger hole boring section of this bit hits your pot wall, it is going to cause your drill motor to kick in your hands. Do not attempt to hold the drill with one hand. Firmly grip your drill with both hands and prop the handle against your leg and tense up for additional stability. If the drill bit binds at all and causes the drill to kick and you do not secure it, you will likely break one or more of the carbide tips off of the bit. We will NOT replace a drill bit with broken tips because it does not represent a defect in workmanship. You've heard a lot about using the right tool for the job, but this is one of those cases where we have to stress having a certain ability for the tool. This is especially true for the 32mm size and UP.
