The LENOX Tools Bi-Metal Speed Slot Arbored Hole Saw with T3, 1-7/8"-48mm, has enhanced tooth geometry that cuts 50% faster than previous LENOX hole saws. Twice as durable as our previous generation when cutting through metal, this bi-metal hole saw with a standard arbor features thicker walls to minimize tooth loss and improve durability. A staircase SPEED SLOT has a wide slot placed low on the hole saw and multiple leverage points to make it easy to work plugs out with a screwdriver. This design effectively removes sawdust and chips and helps prevent plugs from becoming stuck in the saw. 10% taller than previous models, it delivers cleaner cuts through two-by lumber.
From the Manufacturer
The Lenox Tools 1772778 30A Bi-Metal Speed Slot Arbore Hole Saw, 1-7/8-Inch outperforms all competitors in wood cutting, plug removal, and metal cutting applications. The patent pending Speed Slot features a staircase design for easy plug removal. The slot is wider than most and is placed lower on the hole saw with multiple leverage points to easily eject the plug with a standard screwdriver. The hole saw is 10-percent taller than the previous model to deliver cleaner cuts through two-by lumber. The Speed Slot efficiently removes saw dust and chips while producing a fast cut and preventing the plug from getting stuck in the saw. The new hole saw also features up to twice the life of the previous model when cutting metal. An enhanced tooth geometry, a thin kerf design and an advanced coating contribute to the efficiency of the cutting process by removing material faster, therefore generating less heat while cutting.

I have been using the Lenox bi-metal holesaws for a couple decades on everything from high-strength 4140 tubing to cast iron to plastic to wood. They perform very well. Depending on the material and cut, I use some spray coolant or cutting fluid. As long as you run an appropriate RPM and don't overheat the teeth, these hole saws last a long time.

I bought some other tungsten carbide hole saw bcuz it was cheaper and had nothing but a headache with them. Decided to spend a few more bucks and this did the job! Cut out some pipes with an angle using a drill press at a slow rpm and some lube. And still sharp as an eagles claw! Great buy, come with the stem aswell!

The centering drill bit is way to soft, it bent before I even finished one hole.

Drilled right through the side of a '95 Chevrolet 3/4 ton van without complaint and quickly. Advise drilling small pilot hole, then a hole matching the mandrel bit before actually punching the holesaw in (to keep it accurate). If you measure the diameter of the holesaw it will seem small but don't be fooled by this. The set of the teeth cut true to advertised size. Very pleased with this purchase.
