NITTO KOHKI Japan make TCT and HSS cutters are available from 12mm dia upto 100mm dia and in lengths from 25mm to 75mm.
These cutters are made completely in Japan. They provide the best efficiency and value for money in terms of cost per hole. NITTO KOHKI cutters are made specifically for Magnetic Drilling Machines unlike other cutters which tend to damage the machine.
Some of the features of NITTO TCT cutters are :-

- Single pass cutting, no pilot hole required
- Annular part does all the work so small cutting resistance reduces drilling time
- Cutting of slanted, elongated and edge holes is now possible
- Fractional and metric cutter sizes to suit wide range of applications
- Produces little slag and few chips for easy disposal
- Can also be fitted to and used with previous Atra Ace models using a hexagon socket set-screw
- Improved concentricity extends cutter life! One-touch system consisting of three balls inside the arbor body produces a self-centering effect during cutting to improve cutter performance and life

Do you by chance have any unit that can drill through 200mm thick of steel plates. Say like a mini rig. If yes do forward us the details for immediate ordering for we had manage to use the NITTO 5000 to drill maximum of 115mm.
Awaiting your urgent reply.
Many thanks.
Hello,
Thank you very much for contacting us.
Yes WA 5000 has a stroke length of 130mm and this about 115mm is possible.
For 200mm I do not think any machine as such is available although I would recommend you to check out Atra-Ace A-100. it’s a heavy duty manual machine. Please feel free to reply if you need any further information.
