ACCUSiZE N2 Annular Cutters Instruction Manual
ANNULAR CUTTER MANUAL
The annular cutter is applied in drilling holes in steel, copper, brass,
aluminum, stainless steel,
special alloys and rails.
Use Magnetic Seat Drilling Machine
-
Make sure the shank of cutter is tightened to the machine
Cooling -
Use Morse Tapers
-
Add sufficient coolant from the hole on the side of arbor
-
Compressed air can be used for chip removal when drilling material
RPM -
Construction and stainless steel: 0.08-0.12mm/rpm
-
Cast iron: 0.12-0.20mm/rpm
-
Non-ferrous metals: 0.22-0.45mm/rpm
-
Special alloys: 0.05-0.08mm/rpm

Manual Drilling
- Adequate pressure should be given gradually
- Make sure that chips remove smoothly
- It is wiser to remove the chips continuously when cutting deep holes
- Fill the hole with anti-rust oil once the work is done
Automatic Drilling
- It is not recommended to use the automatic model of magnetic drill
- Automatic model may increase the chance of cutter breakage
End of Drilling
- Turn off the motor until the spindle stops rotating
- Remove the chips around the cutter
Operations That May Alleviate The Wear & Fracture of Cutters:
- Ensure sufficient cooling capacity and use proper coolant.
- Good drill pipe rigidity and guide rail clearance can improve drilling accuracy and its use-life.
- Please ensure the flatness and cleanliness between the magnetic base and the work piece.
- When drilling in thin plate, the workpiece shall be tightened. When drilling in large work piece, please ensure the stability of it.
- At the beginning and end of drilling, the feed rate shall be reduced by 1/3.
- For materials with large amount of fine powder during drilling, such as cast iron and cast copper, compressed air can be used to help remove chips without using coolant.
- Please remove the iron filings wound on the cutter in time to ensure smooth chip removal
Common problems and other treatment methods：
When Stuck:
Use non-metallic materials to gently tap the cutter, or gently press the
material for several times to make it loose. You can also remove the cutter
from dill machine and gently tap the center pin to push it out.
Cutter Wear:
Under normal cooling, when the color of iron filings is blue and black, it is
necessary to check the cutter edge
. It is recommended to sharpen and grind the blades when the maximum wear
width is greater than 0.5mm.
Caution:
Follow the safety precautions to avoid accidents.
- Please wear working clothes, gloves, safety goggles, face mask, etc. during operation to avoid danger.
- To prevent hand scratches, please use iron hook to remove the iron chips when drilling.
- Check whether the drill bit has any gap before use. Do not use it, if there are any gap.
- Turn off the motor immediately once the cutter is stuck.
- Ensure that the power of the equipment is disconnected when replacing the cutter.
- Do not touch the cutter when rotating.
- Please keep the cutter in good condition since the cutting edge is hard but brittle.
