Tungsten Carbide Hole Saw, 35mm or 1-3/8 Drill Bit, for Stainless Steel

Our Price: $16.00

Quantity in Stock:64

Product Code: HOLESAW35

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.

5 of 5 Great hole saw for the price April 13, 2019
Reviewer: Larry Sand from Duluth, MN United States  
The trick to using a hole saw like this is slow speed (I used 700 rpm) and even feed.  Plus a little cutting oil.   I have cut 5 holes in SS and the bit is still like new.

1 of 5 Failed on First Use November 22, 2018
Reviewer: Steve Jimmerson from Milton, FL United States  
Started a hole for solder on 1 1/2" TC fitting. After half way through it stopped cutting. Checked and all but one of the carbide teeth were gone. Got out my Lenox bimetal 1 3/8" hole saw and finished the hole. Had to also cut a 7/8" hole in same pot. Used a Southwire carbide hole saw. No problem.

BrewHardware.com response: We can understand that these are not up to the same standards as some of the $40+ versions out there but we've yet to break one on the first use. One thing we want to warn others about is that cutting holes this large is asking a lot of any quality bit and it's very important to brace your drill very firmly, using your leg as a support, to keep the bit from kicking. If it catches and you lose control of the drill, it's easy to damage the bit. This is another case where we were not contacted about the problem so there was no hope for making up for it.

3 of 5 Awesome "Kinda" May 6, 2017
Reviewer: Matt McCann from Corinth, TX United States  
This thing ripped through two kettles like butter. The reason for three stars is the bit. It drilled through the SS just fine but as the teeth of the hole saw engaged it snapped the bit off like a twig. I had to replace it with my own bit which worked fine for the rest of the biild. The price is right.

5 of 5 Like Butter December 7, 2016
Reviewer: Noah Beach from Moncks Corner, SC United States  
Having upgraded my pots from aluminum to stainless steel I need to redrill holes for various items (elements, valves, herms coil, etc). Having used a step bit to drill my aluminum pots, I was loathing attempting the stainless. This bit cut through the stainless like butter. Little bit of cutting oil and was done in literally seconds.

5 of 5 This guy works! October 14, 2016
Reviewer: william spencer from Columbia, MO United States  
I just used this bit to drill the hole for my 1.5 tc flange and it cut thru the stainless wall of my pot with ease. Compared to the step bits I've used in the past this bit is the best by far.
