Cleveland C33083 Square End Mill 0.5in 4 Flute Hss Tin

Product Description

The CLEVELAND C33083 is a double-end, four-flute square end mill designed for material removal in milling operations across a range of workpiece materials. Built from high speed steel (HSS) with a titanium nitride (TiN) finish, this tool delivers improved surface hardness and wear resistance compared to uncoated HSS. The 0.5 inch diameter cutter features a 30-degree helix angle and spiral flute geometry with a 1 inch length of cut. Centercutting capability allows plunge entry into the workpiece. At 4.5 inches overall length with a 0.5 inch straight-cylindrical shank, it fits standard milling machine and machining center collets. Licensed machinists and toolroom operators are the primary users.

This end mill is suited for milling operations in ferrous and non-ferrous materials including steel, cast iron, and non-ferrous metals. The double-end design extends tool life by providing two usable cutting ends per tool. Right-hand cut with right-hand flute geometry is standard for conventional vertical milling setups. The HD-4C series is a regular-length line intended for general-purpose slot milling, profiling, and peripheral cuts in job shop and production environments.

Key Features

• Double-end design provides two cutting ends per tool, extending service life
• TiN coating increases surface hardness and reduces friction at the cutting edge
• Centercutting flute geometry enables direct plunge milling without pre-drilling
• 30-degree helix angle promotes efficient chip evacuation in spiral flute configuration
• Compatible with Weldon flat or straight-cylindrical shank holders
• Right-hand cut and right-hand flute for standard milling machine setups

Compatibility

Designed for use in standard 0.5 inch milling collets, end mill holders, and Weldon flat-style tool holders. Suitable for steel, cast iron, and non-ferrous metal workpieces as noted in the HD-4C series specification.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after seating the shank in the holder. Follow machine manufacturer torque specifications for set screws when using Weldon flat holders.
