Sgs 30301 Square End Mill 1/64 in 2 Flute Solid Carbide

Product Description

The SGS 30301 is a square end mill designed for precision material removal in tight-tolerance machining applications. Built from solid carbide micrograin stock, it delivers the rigidity and edge retention needed for small-feature work. The cutter measures 1/64 inch (0.0156 inch) in diameter with a 1/32 inch (0.0313 inch) length of cut, making it suited for fine detail passes and micro-slot work. A 30-degree right-hand helix promotes chip evacuation while keeping lateral cutting forces manageable at this scale. Two flutes provide adequate chip clearance at minimal diameters. Licensed machinists and tool-and-die professionals are the typical end users for this series.

This end mill is intended for use on CNC machining centers and precision manual mills where small-feature geometry is required. The 1/8 inch straight cylindrical shank fits standard ER collet chucks and similar small-bore toolholding systems. The 1-1/2 inch overall length provides enough projection for typical setups without introducing excessive runout. It is rated for use across a broad range of workpiece materials including hardened materials, cast iron, stainless steel, non-ferrous metals, steel alloys, and high-temperature alloys, per the manufacturer material codes.

Key Features

• 1/64 inch (0.0156 inch) cutting diameter for micro-feature and fine-detail work
• Solid carbide micrograin construction for hardness and edge retention
• 30-degree right-hand spiral flute geometry promotes chip evacuation
• Center-cutting design allows plunge entry in appropriate materials
• Bright/uncoated finish compatible with a wide range of workpiece materials
• Single-end configuration with straight cylindrical shank for standard collet mounting

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and precision mills using 1/8 inch straight-shank ER collets or equivalent toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use an appropriate collet and torque the toolholder to machine-tool manufacturer specifications. At this diameter, runout must be minimized — inspect collets and toolholders for wear before use to avoid tool breakage.
