Features 03 High-rigidity flute shape The corner R flute shape used is the same chipping-resistant high-rigidity flute type used by Epoch Turbo Mills. Because of this, machining with high per-flute feed amounts is possible and high-efficient machining can be achieved. Super CoatingTfTjG • A newly developed nanocomposite coating material that achieves unprecedented withstand temperatures and provides higher hardness through the use of a new structure made up of nanocrystal material. (Oxidation start temperature: 1100° C; Membrane hardness: 3600HV) high feed ossible • Enables high-quality machining...

High Accuracy (Finishing) High Efficiency (Roughing) Reproduces accuracy and performance equivalent to a new product. Recycling kills two birds with one stone by reducing costs and being environmentally friendly. ■ Regrinding of the oval shape to be equivalent to that of new products is possible, without changing the tool diameter of course. ■ Regrinding and recoating is performed according to processing knowhow and design standards based on new products. ■ Since reprocessing is performed under the same environment using the same processing software, coating, and quality control mechanisms as...

Straight Neck type Attention Be careful of the newly developed flute shape when measuring tool diameter or oscillation. The bit is designed with a smaller outer diameter connected to end slave flutes. When measuring tool diameter or oscillation, measure the main flutes.

Pencil Neck type ETRP4 OOOO -00-0000 -TH Item Code

Straight Neck type ETR [Note] © Use a machine having as high rigidity and high accuracy as possible. @ Use the appropriate coolant for the work material and machining shape. ® The cutting conditions shown in this table are intended as general criteria and should be adjusted according to the cutting shape, purpose, machine used, etc. ® If the rotation speed of the machine is insufficient, reduce the rotation speed and feed rate by the same ratios. © For cutting in, set the ramp introduction angle to 1° and set the feed rate to 60 to 70% of the above values. © In the case of using tools with...

Pencil Neck type Be careful of the newly developed flute shape when measuring tool diameter or oscillation. The bit is designed with a smaller outer diameter connected to end slave flutes. When measuring tool diamet

General-purpose condition for low-speed use. Provides stable high-efficiency cutting with the longest tool life. [Note] © Use a highly rigid and accurate machine as possible. © These conditions are for general guidance; in actual machining conditions adjust the parameters according to your actual machine and work-piece conditions. © If the rpm available is lower than that recommended please reduce the feed rate to the same ratio.

Condition which reduces cutting load by reducing the per-flute feed rate. Since cutting resistance can be reduced, it enables use even on machines with low rigidity. ® Feed rates for pencil-neck types are shown for 6Dc and higher in the above table. For straight type and long-neck type of 6Dc or higher, cutting depth in the Z direction should be set about 10% lower than the above values. © Use for cutting contour lines or down cutting. In Z direction, cut at an incline (incline angle: 1 °and reduce feed rate to between 60% and 70%. © It is recommended that speed reduction for corners be set....

Attentions on Safety 1. Cautions regarding handling (1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands. 2. Cautions regarding mounting (1) Before use, check the outside...
