Introduction

This document announces new inserts "SD... .L.." designed for milling cutters S406W..09 and S409W..09. It provides detailed specifications, material compatibility, recommended machining parameters, and ordering information.

Insert Specifications

The new inserts include types SDHW 0903 AESN .Z42, SDHT 0903 AESN .L51, SDNT 0903 AESN .L54, SDKT 0903 AESN .L56, and SDEX 0903 AEFN .L58. All inserts have dimensions approximately 9.52 mm for length and width, thickness 3.2 mm, corner radius 3.4 mm, and a 15° angle.

Material Grades and Coatings

Inserts are available in uncoated cemented carbide (CERMET) and coated carbide grades. The document lists various grades such as HT, HW, and HC, with corresponding codes (e.g., N3105, F1040, T518M, T533) indicating toughness and coating types.

Material Compatibility

The inserts are suitable for machining a wide range of materials classified by ISO and DIN standards:

• P: Steels (non-alloy, low alloy, alloyed)
• M: Stainless steels (martensitic, austenitic, duplex)
• K: Cast irons (grey, spheroidal graphite, malleable)
• N: Non-ferrous metals (aluminum alloys, copper alloys)
• S: Heat resistant alloys and titanium
• H: Hardened and hard materials

Recommended Machining Parameters

Parameters are provided for cutting speed (Vc), feed per tooth (fz), and machining type (finishing, medium, roughing) depending on material group and insert grade. For example:

• Non-alloy steel: Vc 260-350 m/min, fz 0.1-0.2 mm
• Aluminum alloys: Vc up to 950 m/min, fz 0.06-0.15 mm
• Heat resistant alloys: Vc 85 m/min, fz 0.05-0.08 mm

Formulas for calculating spindle speed (n), feed per revolution (fn), and feed speed (Vf) are included, with correction factors (Kae) based on radial depth of cut (ae) relative to cutter diameter (D).

Insert Availability and Pricing

Insert availability is indicated as "in stock" or "on request." Prices in euros are listed for each insert type, ranging approximately from €10.35 to €13.12.

Additional Information

The document includes contact details for SAU S.p.A. and its Modena subsidiary, along with accreditation information.
