Sgs 02656 Square End Mill 0.075 in 4 Flute Altin Carbide

Product Description

The SGS 02656 is a single-end square end mill designed for precision metal removal in demanding milling applications. Manufactured from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-temperature cutting environments where tool life and edge integrity matter. The cutting diameter is 0.075 inches with a 3/8 inch (0.375 inches) length of cut. Four right-hand spiral flutes at a 30-degree helix angle promote efficient chip evacuation and stable cutting action. This tool is center-cutting, allowing plunge entry as well as standard peripheral milling. Machinists and tool-and-die professionals working in steel, stainless, and hard alloys are the primary users.

This end mill is suited for fine-detail milling operations where a small-diameter tool is required, such as slotting, profiling, and contouring in ferrous metals, hardened steels, and similar high-temperature alloys. The 1/8 inch straight-cylindrical shank fits standard collet systems commonly found on CNC machining centers and manual mills. The 2.5 inch overall length places this in the extended length category, providing reach into deeper features while the rigid micrograin carbide substrate resists deflection at this diameter.

Key Features

• 0.075 inch cutting diameter with a mill diameter tolerance of +0.000 to -0.001 inches for precise fitment
• AlTiN coating provides high heat resistance and extended tool life in ferrous and hardened materials
• 4 right-hand spiral flutes at a 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows direct plunge milling as well as side and slot milling
• Micrograin solid carbide substrate delivers rigidity and wear resistance at small diameters
• Straight-cylindrical 1/8 inch shank with h6 shank diameter tolerance for consistent collet grip

Compatibility

Designed as a standard replacement or new-application solid carbide square end mill compatible with 1/8 inch collet toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into a clean, undamaged collet to the recommended engagement depth and torque the collet nut per the toolholder manufacturer specification. Inspect the cutting edges for chips or coating damage before use, particularly at this small diameter where edge condition directly affects dimensional accuracy.
