SHC M2 TYPE ANNULAR CUTTER HIGH SPEED STEEL

High Speed Steel Annular cutter (HSS)

The days of grabbing a magnetic drill and plowing a twist drill through the steel, blue chips flying, are gone. Annular cutters are the standard for hole making with magnetic drills. These cutters make the job easier, more efficient and save shops money.

High-speed steel (HSS) annular cutters

3keego HSS Annular Cutters are designed to drill holes on mild to hard steels. HSS Annular Cutters are made from M2 and M42 HSS material. Comes with Titanium Coated for a longer life span.

An HSS annular cutter is a hollow tool that provides multiple cutting edges. Annular cutters drill a burr-free hole by cutting material around the periphery of the hole and ejecting the center as a solid usable slug. It’s an efficient way to create holes ½” to 4” diameter and up to 3” deep. Final holes are smooth and no reaming, predrilling or step drilling is required. The wall thickness of the cutter is only ¼” thick so that no matter what size hole you are cutting, you are only removing a small amount of material around the edge of the hole.

Annular cutters are manufactured in several different configurations including carbide-tipped annular cutters and carbide tipped stacked annular for maximum cutting performance.

Another factor in the HSS annular cutter equation is tooth geometry. Cutting multiple plates at once does not use the same tooth angles as when cutting a single sheet. There are different geometries and features companies put on annular cutters to help ensure the most success.

And don’t forget coatings. Manufacturers can apply a variety of different coatings to increase the tool life in harder materials. Remember, you get what you pay for. Also, look for annular cutters that can be re-sharpened. That will save you even more money in the long run.

Other important factors

After you choose the proper annular cutter, there are other factors to help lead you to greater success.

1. Always use coolant and use the machine's thru-the-spindle coolant whenever possible. Cutting tools love coolant.

2. Use good steady feed pressure. Make sure you are pulling a good chip.

3. Aim to get close to the recommended RPM for the cutter and material. Your tool life will thank you.

4. Use a sharp annular cutter, because sharp edges just cut better.

5. Ensure the arbor and mounting system holding the tool is rigid and secure otherwise you can quickly dull or break a cutter.

6.Always use the pilot pin. Slugs must be ejected.

Benefits and Advantages of  HSS Annular Cutter

Fast (Time Saving)

Since an annular cutter removes only the material at the periphery of the hole, it is 3 to 4 times faster than twist drill bit. Besides, an annular cutter with pilot pin can finish a hole by one operation without pre-drilling for a pilot hole.

Efficient (Energy Saving)

Due to the annulus shape and thin wall design (4mm for each diameter), the annular cutter does not have to drill the complete material of the hole which lowers the energy, effort and thrust compared to conventional drill bits.

Less wear (Longer life)

While the cutting surface is distributed to multiple cutting edges, the contact between annular cutter and the material becomes much less. Also, no matter how big the hole you are going to drill, the thin wall (4mm) of the annular cutter will cut only at the periphery of the hole. Therefore, an annular cutter with a good design has a longer service life with best performance.

Clean Hole (Burr-free)

With specially designed cutting teeth geometry compared to conventional drill bits, an annular cutter can create a burr-free hole in metal. Besides, since there is only a few chips made, the cleaning work after drilling is very easy and fast.
