Sgs 46621 Square End Mill 8mm 7 Flute Solid Carbide Altin

Product Description

The SGS 46621 is a 7-flute solid carbide square end mill designed for high-efficiency milling in demanding shop environments. With an 8 mm (0.315 inch) mill diameter, a 20 mm (0.787 inch) length of cut, and a 63 mm (2.480 inch) overall length, this tool is built for rigidity and material removal in a compact profile. The micrograin carbide substrate and AlTiN coating make it well suited for elevated cutting temperatures and abrasive workpiece materials. It is intended for use by machinists and tooling professionals running CNC milling equipment.

The 46621 is rated for use across a broad range of workpiece material categories including hardened steels, cast irons, stainless steels, general steels, and heat-resistant superalloys, as indicated by material codes H, K, M, P, and S. The 35-degree helix angle supports smooth chip evacuation at higher feed rates. The straight-cylindrical shank at 8 mm (0.315 inch) diameter with h6 tolerance fits standard ER and end mill holders. This is a single-end, right-hand cut, right-hand flute configuration suited to conventional CNC milling centers.

Key Features

• 7-flute design increases tool engagement and productivity in finish and semi-finish milling passes
• AlTiN coating provides heat resistance and extends tool life in ferrous and superalloy materials
• Micrograin carbide substrate delivers superior hardness and wear resistance
• 35-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge entry into workpiece material
• Straight-cylindrical shank with h6 tolerance ensures accurate fitment in standard collet and end mill holders

Compatibility

Designed for use in CNC milling applications involving hardened steels (H), cast irons (K), stainless steels (M), general steels (P), and heat-resistant superalloys (S), as defined by SGS Series 66M material group ratings.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from its holder. Verify holder bore diameter and runout tolerance before seating the tool, as excessive runout will accelerate edge wear on a 7-flute geometry. Follow the tool manufacturer's recommended speeds and feeds for the target workpiece material and coating type.
