Harvey Tool 33247 Square End Mill 3/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 33247 is a solid carbide square end mill designed for precision milling in a wide range of metalworking applications. With a 3/64 inch (0.0470 inch) mill diameter and a 1.8 mm (0.0710 inch) length of cut, this is a miniature long-reach, stub-flute end mill built for tight-tolerance work in confined areas. The 3-flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The bright/uncoated finish allows direct inspection of the carbide substrate. Machinist and CNC programmers working with small-diameter tooling will recognize this as a purpose-built tool for fine-feature milling in demanding materials.

This end mill is suited for use on CNC machining centers and manual mills where small-diameter, long-reach cutting is required. It is rated for use in steel, stainless steel, cast iron, aluminum and non-ferrous materials, and CFRP (carbon fiber reinforced polymer) materials. The extended reach design with a 0.25 inch reach length makes it well suited for deep-pocket and slot milling where standard-length tooling cannot access the workpiece geometry.

Key Features

• 3/64 inch (0.0470 inch) mill diameter for fine-feature and miniature milling
• Solid carbide construction for rigidity and wear resistance in hard materials
• 3-flute, spiral flute geometry with 30-degree helix for efficient chip removal
• Long-reach, stub-flute series with 0.25 inch reach length for deep-pocket access
• Center-cutting capable, right-hand cut and right-hand flute direction
• Bright/uncoated finish suitable for aluminum, non-ferrous, and ferrous materials

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 1/8 inch shank diameter. Compatible workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and CFRP materials.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out. Secure the 1/8 inch shank in a properly sized collet or end mill holder, ensuring adequate grip length to prevent pullout under cutting loads. Miniature end mills require careful runout verification before starting a cut. Do not exceed manufacturer-recommended speeds and feeds for the workpiece material and depth of cut.
