RS0112

By enabling uninterrupted machining, it reduces shop‑floor workload and improves operational efficiency.

In today’s machining environments, where automation and labour saving are increasingly advancing, higher productivity is strongly demanded.

Mitsubishi Materials’ multi‑functional shoulder milling cutter “RS0112” features a proprietary V‑insert geometry that delivers an excellent balance of sharp cutting performance and high strength. This enables stable, long‑duration machining, making RS0112 an ideal solution not only for high‑efficiency machining but also for meeting the growing needs of automation and reduced manpower.

By strongly supporting uninterrupted machining, RS0112 contributes to reducing shop‑floor workload while further improving operational efficiency.

Insert Features

High Sharpness Creates High‑Precision Surface Finish
Strength Enables Stable Machining

High‑Quality Surface Finish

The surface finish achieved by the V‑insert geometry also reduces the need for secondary operations.

SCM440: Surface finish accuracy comparison

The low cutting‑resistance design allows smooth chip evacuation, achieving a high‑quality bottom surface and step‑free wall surfaces.

Chipbreaker System

Three chipbreaker geometries are available to suit different machining applications.

Cutter Body Features

Unwavering Durability

RS0112 has been developed with a relentless focus on cutter body performance, delivering unwavering durability.

SCM440: Insert seat wear comparison

Even under four times the number of impact cycles compared to conventional products, insert seat wear is evenly distributed, resulting in improved durability of the cutter body.

Balance between Cutting Resistance and Fracture Resistance

The cutter body is designed to pursue durability while reducing cutting resistance.

SCM440: Cutting resistance comparison

Compared to conventional products, all cutting resistance components—feed force, principal cutting force, and back force—are reduced, enabling stable machining with lower loads during operation.

Surface Finish Comparison on Small Machine Tools (BT30)

Stable machining is achieved even on small machine tools due to low cutting forces.

Cutting Performance

It delivers high performance across a wide range of workpiece materials.

SUS304: Fracture resistance comparison (Dry cutting)

Low cutting resistance reduces edge chipping, delivering over eight times longer tool life than conventional products.

SUS304: Fracture resistance comparison (Wet cutting)

Compared to conventional products, cutting edge thermal cracking is suppressed, achieving more than 1.25 times the tool life.

FCD700: Fracture resistance comparison

Compared to conventional products, the absence of micro chipping that affects tool life results in more than 1.5 times the tool life.

Ti6Al4V: Cutting length comparison

Even in titanium alloy machining, significant extension of tool life is achieved without chipping.

SCM440: Fracture resistance comparison

By reducing cutting resistance, cutting edge load is lowered, resulting in more than double the tool life of conventional products.

Customer Application Example

Courtesy of Mashiko Manufacturing Co., Ltd.

Compared to conventional products, the step height was reduced to one‑tenth, and continuous machining was achieved without insert adhesion or flaking.

Machined Mechanical Component – S45C Shoulder Milling

Tool life was doubled compared to conventional products, with clearly superior results also achieved in surface finish quality.

Mechanical Part Machining Example – SS400 Face Milling

Even when the depth of cut (ap) was doubled compared to conventional products, no fracture occurred.
As a result, productivity doubled and tool life increased by 2.5 times. In addition, machining noise was reduced, and cutter pass marks on the finished surface were eliminated.
