BCMT090302R-G55 WSP45G Fräswendeschneidplatte – Walter Tools, Tiger·tec Gold

The BCMT090302R-G55 WSP45G is an indexable milling insert designed for productive finishing and semi-finishing of steels, stainless steels and heat-resistant superalloys.

• Tiger·tec Gold PVD coating
• Versatile for steel, stainless steel, superalloys
• 7° relief angle for stable cutting
• 0.2 mm corner radius for fine edges

High-performance cutting for demanding materials

The BCMT090302R-G55 WSP45G grade, built on Walter Tools' Tiger·tec Gold platform, delivers a balance of toughness and wear resistance that benefits repeated milling operations. The PVD-coated carbide substrate supports high temperatures and resists abrasive wear, which helps to maintain the cutting edge during extended runs. For workshop managers aiming to raise throughput, this combination reduces tool change frequency and supports stable process windows when machining steels (P), stainless steels (M) and heat-resistant alloys (S).

Geometry that improves surface quality and process stability

The insert’s parallelogram 75° relief and 7° relief angle contribute to a predictable chip flow and cutting force direction, which translates directly into improved part finish and dimensional consistency. The 0.2 mm corner radius helps to avoid premature edge chipping while enabling fine contour work; when combined with the G55 chipbreaker, the result is controlled chip formation across a range of feeds and depths of cut. These geometry choices reduce vibration and promote repeatable results on CNC milling centres.

Durability that lowers unit cost and downtime

Thanks to the coated carbide grade and the Tiger·tec Gold coating, the insert offers extended edge life under cyclic thermal loads and mixed-material batches. The robust coating chemistry improves resistance to built-up edge and flank wear, while the substrate toughness supports impact resistance during interrupted cuts. The predictable wear behaviour supports preventive maintenance intervals and contributes to lower overall tooling cost per part when compared with uncoated or less advanced grades.

Practical fitment and machining guidance

Designed as a standard BCMT-style insert in size 09 with thickness 03, the component fits many common milling cutters and adapters, making it straightforward to integrate into existing tool inventories. For best results, select cutting data aligned with medium to high speeds for steels, reduced cutting speed for stainless and heat-resistant alloys, and monitor chip evacuation to match the G55 chip geometry. The insert’s tolerance class M and execution T ensure consistent seating and repeatable orientation in the pocket.

FAQ

What materials is this insert suitable for? The BCMT090302R-G55 WSP45G insert from Walter Tools is developed for machining steels (P), stainless steels (M) and heat-resistant alloys/titanium (S), offering balanced wear resistance and edge stability across these groups.

How does the Tiger·tec Gold coating improve performance? Tiger·tec Gold PVD coating on the BCMT090302R-G55 provides enhanced thermal and abrasive wear resistance, which helps to preserve cutting edges and extend lifetime during demanding milling cycles.

Which chipbreaker is fitted and what is its effect? This insert features the G55 chipbreaker, which promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of recutting in typical milling conditions.

What is the significance of the 0.2 mm corner radius? A 0.2 mm corner radius balances sharpness and edge strength, allowing finer surface detail while lowering the chance of edge chipping during light to moderate engagement cuts with the BCMT090302R-G55.

Is the BCMT090302R-G55 compatible with standard BCMT toolholders? Yes, the insert conforms to the BCMT geometry and size 09 thickness 03, making it compatible with standard toolholders designed for that insert style and size.
