Cleveland C33693 Square End Mill 3/16 in 2 Flute Hss Ticn

Product Description

The CLEVELAND C33693 is a double-end square end mill designed for precision material removal in ferrous and non-ferrous machining applications. Built from high speed steel with a titanium carbonitride (TiCN) finish, this tool delivers increased surface hardness and wear resistance compared to uncoated HSS tooling. It features a 0.1875 inch cutting diameter, a 7/16 inch length of cut, and a 30-degree helix angle with spiral flutes. The right-hand cut, right-hand flute geometry provides efficient chip evacuation. This end mill is installed and operated by machinists and tool-and-die professionals using CNC mills, knee mills, or manual milling machines.

The C33693 belongs to Cleveland's HD-2 series and is suited for milling cast iron, steel, and non-ferrous metals in general-purpose machining environments. With a 3/8 inch straight-cylindrical or Weldon flat shank and a 3-1/4 inch overall length, it fits standard ER collets and Weldon-style side-lock holders. The centercutting capability allows direct plunge entry, making it practical for slot milling, profiling, and step milling operations where drilling a pilot hole first is not required.

Key Features

• Double-end design provides two usable cutting ends, extending tool life between replacements
• TiCN coating increases surface hardness and reduces tool wear on ferrous and non-ferrous materials
• 30-degree helix angle promotes smooth cutting action and efficient chip removal
• Centercutting geometry allows direct plunge milling without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral flute configuration compatible with standard milling machine spindle rotation
• Straight-cylindrical and Weldon flat shank accepts both collet chucks and side-lock tool holders

Compatibility

Designed for milling cast iron, non-ferrous metals, and steel. Compatible with standard 3/8 inch ER collets, Weldon-style side-lock holders, and similar toolholding systems used on CNC and manual milling machines. Suitable for applications within the HD-2 series length-of-cut range of 0.30 to 0.50 inches.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the milling machine spindle is fully stopped and the machine is powered down before changing or seating the end mill. Verify shank engagement depth meets the toolholder minimum grip length before operation. Inspect the TiCN coating and cutting edges for chips or wear before each use, as a damaged edge on an HSS end mill can cause work-piece surface defects or tool breakage at elevated feed rates.
