Lenox 3001616L – Frequently Asked Questions
1) What sizes does the Lenox Speed Slot bi-metal hole saw come in?
Thirteen diameters across the Lenox Speed Slot bi-metal line: 1", 1-1/4", 1-5/8", 1-7/8", 2-1/8", 2-3/8", 2-3/4", 3-1/4", 3-3/4", 4-3/8", 4-5/8", 5-1/2" and 6". Each diameter is its own part number, so order by size, for example 3001616L for the 1 inch and 3009696L for the 6 inch.
2) Does the Lenox bi-metal hole saw come with an arbor, or do I need to buy one separately?
An arbor is not part of the saw. The cutting instructions start with selecting the appropriate arbor and securing the hole saw to it, so plan on an arbor with a pilot drill sized to the cup you are running. Larger cups generally take a heavier arbor than the small ones, so if you are buying a spread of sizes check that one arbor covers the range you need.
3) Will a bi-metal hole saw cut steel, or is it only good for wood?
It does both. The construction pairs a carbon steel backing with high speed steel cutting edges, so the teeth hold up in sheet metal, steel plate and metal fabrication work while the larger tooth geometry still clears wood fast. That is why electricians use the same cup for a knockout in a panel and a pass-through in a stud.
4) What is Speed Slot on a Lenox hole saw and does it actually help?
Speed Slot is a staircase-shaped slot cut into the side of the cup. You get a pry point at several depths, so instead of fishing a stuck plug out with a screwdriver through a single round hole, you lever it out through the step nearest the plug face. On repetitive work, like running a row of holes for conduit, that is where the time goes.
5) Which hole saw size do I need for common electrical conduit runs?
Size the cup to the fitting, not the conduit trade size, since a connector or box knockout is wider than the pipe. The Lenox Speed Slot range covers the usual electrical sizes in close steps from 1" up through 2-3/4", then jumps to 3-1/4", 3-3/4", 4-3/8", 4-5/8", 5-1/2" and 6" for duct, vent and larger core work. Measure the outside of the fitting you are passing through and pick the next size up.
6) How do I keep a bi-metal hole saw from burning up the teeth in metal?
Run it slow. Start at low speed to set a clean entry ring, then hold moderate speed with steady, even pressure rather than leaning on the drill, which is what glazes teeth. Clear the slug through the Speed Slot rather than forcing the cup deeper on a packed plug, and brush the teeth clean and check for wear at the end of the job.
7) Is this hole saw suitable for HVAC and plumbing work, or is it an electrical-only tool?
It is a multipurpose cup. Alongside electrical box and wiring access holes, it is used for pipe routing and fixture installation in plumbing, and for ductwork connections and equipment mounting in HVAC. The larger diameters up to 6 inches are what make the duct and vent work practical.
8) Why do the teeth on these hole saws chip out and does this one hold up better?
Tooth loss usually comes from thin cup walls flexing under load in metal. The Speed Slot cups are built with increased wall thickness specifically to cut down tooth loss and extend life, which matters most on the bigger diameters where there is more tooth engaged at once.
