Robbjack SS-2-037 Square End Mill 0.037 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-037 is a solid carbide square end mill engineered for precision milling in tight-tolerance applications. It features a 0.037-inch cutting diameter and a 0.0555-inch length of cut, making it well suited for fine detail work, slot milling, and profiling in harder materials where rigidity and edge retention matter. The 1/8-inch shank diameter and 1.5-inch overall length give it a compact, stub-length profile that reduces deflection. With a 30-degree helix angle and spiral flute geometry, this tool promotes efficient chip evacuation and smooth cutting action. It is uncoated and centercutting, allowing plunge entry. Machinists and toolroom operators working in CNC machining centers install and run this end mill.

This end mill is designed for applications requiring sub-0.040-inch cutting diameters, including micro-slot milling, fine contour work, and detail profiling in metals and engineered materials. The stub length type is a common choice on CNC machining centers where reduced overhang is needed to maintain accuracy in small-feature work. Right-hand cut and right-hand flute orientation follow standard spindle configuration on the majority of vertical machining centers.

Key Features

• 0.037-inch cutting diameter with a tolerance of plus or minus 0.0005 inches for consistent, repeatable results
• Solid carbide construction for rigidity and wear resistance in demanding materials
• 30-degree helix angle with spiral flute geometry promotes chip flow and reduces heat buildup
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute - compatible with standard CNC spindle rotation
• Stub length profile minimizes deflection at very small diameters
• Uncoated finish suitable for applications where coating is not required or preferred

Compatibility

Designed as an OEM-style replacement or direct-run tool in the ROBBJACK SS-2 series, compatible with standard 1/8-inch collets and tool holders on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the 1/8-inch shank fully and evenly in a matched collet or end mill holder to the manufacturer-specified engagement depth, and inspect the tool for runout before beginning a cut. At very small diameters, excessive runout or improper seating significantly increases the risk of tool breakage.
