Harvey Tool 44908 Square End Mill 1/8 in 1 Flute Carbide

Product Description

The HARVEY TOOL 44908 is a single-flute, solid carbide square end mill designed for precision milling applications where tool rigidity and surface finish are critical. With a cutter diameter of 0.125 inches and a length of cut of 0.5 inches, this end mill is built for slotting, profiling, and contouring in tight geometries. The downcut flute geometry pulls chips upward, reducing surface tearout on the top face of the workpiece. At 2 inches overall length with a 0.25-inch shank diameter and a 22-degree helix angle, it fits standard collet chucks used on CNC mills and routers. The bright, uncoated finish suits a wide range of materials without the added thermal barrier of a coating.

This end mill is suited for CNC machining centers and router setups where a small-diameter, single-flute tool is required for fine detail work, narrow slot cutting, or finish passes in materials such as aluminum, plastics, composites, and non-ferrous metals. The downcut geometry makes it a common choice for woodworking CNC routers and composite panel work where top-surface finish quality matters. Machinists and CNC operators in job shops, production facilities, and prototyping environments are the primary users of this tooling.

Key Features

• 0.125-inch cutter diameter for fine detail and narrow slot applications
• Single-flute design maximizes chip clearance at higher feed rates in soft materials
• Downcut flute geometry reduces surface tearout on the top face
• 22-degree helix angle for balanced cutting forces
• Solid carbide construction provides rigidity and wear resistance
• Bright, uncoated finish suitable for non-ferrous metals, plastics, and composites

Compatibility

Designed for use in standard 1/4-inch collet chucks on CNC milling machines and CNC routers. Fits any machine tool spindle that accepts a 0.25-inch shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and at rest before changing tooling. Seat the shank to the recommended minimum insertion depth in the collet to avoid runout and tool pullout during cutting. Verify tool runout with a dial indicator before beginning production cuts when tight tolerances are required.
