Sgs 42665 Corner Radius End Mill 6mm 5 Flute Altin Carbide

Product Description

The SGS 42665 is a solid carbide corner radius end mill designed for high-performance material removal in steel, stainless steel, cast iron, superalloys, and titanium. It features a 6 mm cutting diameter, a 0.50 mm (0.0197 inches) corner radius, and five flutes with a high-helix, right-hand cutting geometry. The tool is coated with AlTiN (Ti-NAMITE-A), providing thermal resistance and hardness suited to aggressive cutting conditions. At 75 mm overall length with a 6 mm straight-cylindrical shank, the 42665 fits standard end mill holders and is intended for use by machinists and tool-and-die professionals in production and job-shop environments.

This end mill is rated for both roughing and finishing operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The 6 mm length of cut (25 mm, or 0.8268 inches) and normal pitch classification make it well suited to slotting, profiling, and contouring passes where a corner radius is required to reduce stress concentration and improve surface finish. The Series 55C designation places it in SGS's extra-long category for applications requiring additional reach beyond standard proportions.

Key Features

• AlTiN coating (Ti-NAMITE-A) for high heat resistance in ferrous and hard-material cutting
• 5-flute, high-helix, right-hand geometry supports both roughing and finishing in a single tool
• Variable index flute spacing reduces chatter and harmonic vibration
• 0.50 mm corner radius minimizes corner chipping and extends tool life at workpiece edges
• Solid carbide construction provides rigidity and wear resistance in demanding cuts
• Straight-cylindrical shank with h6 tolerance for accurate, repeatable seating in end mill holders

Compatibility

Designed for use with standard end mill holders. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, and H).

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per shop safety procedures. Secure the shank in a clean, properly sized end mill holder and torque the retention mechanism to the holder manufacturer's specification. Inspect the corner radius and cutting edges for damage before each use. Do not exceed the tool's rated parameters for the workpiece material being cut.
