Cleveland C32066 Square End Mill 7/8 in 2 Flute Hss HGA-2

Product Description

The CLEVELAND C32066 is a 2-flute, long-series square end mill designed for material removal and profiling in non-ferrous metals. Manufactured from high speed steel (HSS) with a bright/uncoated finish, it features a 7/8 inch cutting diameter, a 3-1/2 inch length of cut, and a 5-3/4 inch overall length. The 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. A right-hand cutting and right-hand flute direction configuration is standard. This end mill is center-cutting, allowing it to plunge directly into the workpiece. It is used by machinists and tool-and-die professionals in CNC and manual milling applications.

The C32066 is suited for milling operations on non-ferrous materials such as aluminum, brass, copper, and similar alloys. The long length of cut — 3-1/2 inches — makes it appropriate for deep-pocket milling, slotting, and profiling where shorter end mills cannot reach. The straight-cylindrical shank with Weldon flat provides secure tool holding in standard end mill holders and set-screw chucks. This is a single-end tool from the Cleveland HGA-2 series.

Key Features

• 7/8 inch cutting diameter with matching 7/8 inch straight shank and Weldon flat for positive tool retention
• 3-1/2 inch length of cut supports deep-pocket and extended-reach milling operations
• 37-degree spiral flute helix promotes efficient chip evacuation in non-ferrous materials
• Center-cutting design allows direct plunge entry without pre-drilling
• Bright/uncoated HSS construction — compatible with standard cutting fluid and oil mist coolant strategies
• Right-hand cut, right-hand flute, single-end configuration — conventional milling orientation

Compatibility

Designed for use on non-ferrous metals including aluminum, brass, and copper alloys. Fits standard end mill holders, collet chucks, and Weldon-style set-screw holders accepting a 7/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Secure the Weldon flat against the set screw to prevent tool pull-out under axial cutting loads. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Do not exceed the machine spindle's rated RPM for the selected tool diameter and material combination.
