Chipbreaker geometry

① AM3 designed for a wide range of machining from medium to light depths of cut
② Sharp cutting edge for shearing material

Achieves excellent surface finishes even at high feed rates - wiper style insert (AM3-WP)

A. For conventional tools feed rate is reduced to maintain good surface finish which results in chip control issues.
B. If the feed rate is increased, the surface finish will deteriorate.
C. Inserts with a wiper help to maintain chip control and surface finishes even during high feed machining.
*when applying the DCGT... AM3-WP insert, use with our SDJC type holder (lead angle 93 degrees)

Case study

Front turning
Material :
SUS440C
Cutting speed :
55 m/min
Feed :
0.04 mm/rev
DOC :
0.4 mm

After running 900 parts, the competitor's insert resulted in a dimensional change of 0.041mm while DM4 had better machining stability with parts showing dimensional change of only 0.02mm after the same amount of parts machined.

Front turning
Material :
SUS304
Cutting speed :
30 ～ 80 m/min
Feed :
0.015 mm/rev
Replacement :
0.15 mm
DT4 TFD11FR05AM3

1,500 pcs / corner
Conventional tool

700 pcs / corner

The current tool resulted in a measured surface finish of Ry = 10.2μm with 500 parts machined and a 0.1mm dimensional change from the start of production.
DT4 achieved dimensional consistency and machined 1000 parts all with surface finish of Ry 2.3 μm.
