What is the annular cutter?

The annular cutter is usually used for magnetic drills, but it also works well on milling machines, and can even be applied to drill presses. It is a more expensive and effective alternative to spiral drills and standard hole saws.

What are annular cutters used for?

The annular cutter is a special bit used to drill through steel. Just like the wood hole saw, the circular cutter can only cut the outer edge of the hole. The annular cutter is designed for fast and efficient hole processing, and only cuts the material required to produce high-quality holes.

The advantage of the annular cutter is that it has clean and precise large holes and does not require huge horsepower because it only cuts a small part of the material compared to other drilling or milling options. We provide high-quality carbide tip cutters (TCT annular cutter) and standard high-speed steel (HSS annular cutter) in standard and metric sizes, which can be re-sharpened many times to achieve the lowest single hole cost.

What is HSS annular cutter?

HSS annular cutter can be used for various magnetic drilling machines. They can be widely used for drilling steel, copper, aluminum, stainless steel and plastics, whether plate or tube.

HSS annular cutter has a unique tooth geometry, which can provide clear cutting, fast feed speed, small vibration, smooth hole surface and long tool life.

Features of HSS annular cutter

1. HSS annular cutter, suitable for most metals. Has become the preferred tool for modern steel structure drilling and ring groove processing.

2. HSS annular cutter has the characteristics of high drilling efficiency, light drilling and labor saving.

3. HSS annular cutters use high-quality high-speed steel M2 material, smooth cutting, high drilling efficiency, drilling performance is significantly better than ordinary two-edged twist drills, each can drill 700 to 1000 holes.

4. Use a high-speed steel drill bit with coolant when drilling, which can improve the wear resistance of the drill bit and can choose a higher cutting speed.

5. When in use, layered cutting and low-friction cutting geometry can reduce blade chipping and improve chip removal performance.

6. In addition to the common handle types, there are also a variety of handle types (right-angle handles, four-hole handles, Fein handles, internal threaded handles), which are suitable for various imported drilling rigs, Taiwan drilling rigs, domestic drilling rigs and drilling rigs;

7. The specifications range from Φ12mm to Φ100mm, and the cutting depths are 25mm, 35mm, 50mm, 75mm, 100mm;

What is a TCT annular cutter?

TCT annular cutter are designed with spiral flutes and geometrically arranged tungsten carbide tips for efficient cutting at high speeds with less heat resistance.  Ideal for cutting hardened steel, stainless, and other difficult materials.

Features of TCT annular cutter

1. With a unique cutting edge geometry, can provide high-efficiency cutting, fast speed, low vibration, smooth hole surface and long tool life. Its drilling speed in steel is 10 times faster than standard twist drills.

2. It has the advantages of durability, super strength and longer life.

3. TCT annular cutters with welded shank can be used for most major magnetic drills, and can also be used for milling machines with tool holders and large drilling machines.

4. TCT annular cutter can cut almost all types of steel smoothly and easily, including extremely difficult-to-cut materials such as characteristic stainless steel, titanium, hardened steel and rail steel.

The operation steps

1. Insert the power plug, the drill is roughly aligned to the processing position, and then the electromagnet switch is turned on, so that the electro-magnet adsorption on the surface of the iron and steel and other magnetic materials(generally plate thickness should be greater than 20mm).

2. For a magnetic seat equipped with a rotary table, loosen the handle of the turntable, move the machine frame to drive the machine frame to make the bit towel center aligned to the working position, and then screw down the handle.

3. The support screw should be adjusted o make it light to the surface of adsorption.

4. The open electric switch.

5. The grip feed handle slowly drilling operations.

Special note for three-phase magnetic base drill should pay attention to rotation of the electric drill when does not meet the requirements will wire the two wires (phase) swap, confirming the direction of rotation of the drill right. Never a wrong connection of grounding wire.
