Product Description:

Our hole saws are designed to last, with high speed steel teeth electron welded to a high carbon steel body. This ensures maximum durability and a long working life.

With a 4/6 variable pitch tooth design, our hole saws offer improved chip clearance and require lower feed pressure with varying gullet depth. This allows for a more efficient and effective cutting experience.

One of the benefits of our hole saws is less heat build up, which ensures the teeth remain sharp for a longer period of time. This also means that the saw will operate more efficiently, resulting in faster and more aggressive cutting performance.

If you use a cooling lubricant, you can extend the life of your hole saw by up to 500%. This is an easy way to ensure that you get the most out of your tool.

Our Bimetal Hole Saws with HSS teeth are cutting tools that are designed to be rugged and accurate. They can cut through a variety of machinable materials up to 38mm thick. And with sizes ranging from 14mm to 210mm in diameter, they can be used in a wide range of machines, including portable electric tools, air tools, drill press, lathes, boring mills, milling machines and some other machines with rotating spindles.

The HSS teeth of our Bimetal hole saws are recommended for cutting steel, cast iron pipe, steel plates, aluminum, copper, brass, stainless steel, wood, and plastic. This makes them an incredibly versatile tool for any job.

Our hole saws are available in a range of sizes to fit your needs. The 14mm to 30mm diameter hole saw has a 1/2-20UNF threaded connecting, while the 32mm to 210mm diameter hole saw has a 5/8-18UNF threaded connecting. No matter what size you need, we have you covered.
