[ ! ]When ordering manufactured products, be sure to confirm the ordering examples as the points below differ when ordering a stocked product.
(1) "LN-" is prepended to the start of the model number. (2) "S" is appended to the end of the model number.(3) The order for specifying the "length under neck" and "radius" is the opposite from that of stocked products.
For Cutting Conditions, Refer to >>Click here.

● Radius (R) accuracy is of high quality at ±5 μm (compared to our other products), allowing for high-precision deep groove machining to be achieved.
● It adopts a 4-flute shape to allow higher feed configurations compared to machining with 2-flute models. 
| Number of Flutes(sheet) | 4 | Model | Long Neck Radius | Coating | For High Hardness (Silicone-Based) |
