Cleveland C33791 Square End Mill 1 in 2 Flute Hss Tin HG-2

Product Description

The CLEVELAND C33791 is a 2-flute square end mill designed for milling operations in steel, cast iron, and non-ferrous metals. Built from High Speed Steel (HSS) with a Titanium Nitride (TiN) finish, it combines wear resistance with edge retention across a range of ferrous and non-ferrous workpiece materials. The 1-inch mill diameter and 30-degree right-hand spiral flute geometry support efficient chip evacuation and consistent surface finish. Centercutting capability allows for plunge entry without a pre-drilled pilot. This end mill is handled by machinists, tool-and-die makers, and maintenance professionals operating vertical mills and machining centers.

The C33791 is suited for general-purpose milling applications in job shops, production environments, and maintenance operations. Its straight-cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw collet systems. The regular-length geometry makes it appropriate for face milling, shoulder milling, slotting, and light ramping cuts where extended reach is not required. Primary workpiece materials include steel, cast iron, and non-ferrous metals.

Key Features

• 1-inch mill diameter with 1.5-inch length of cut for versatile milling depth
• 2-flute geometry promotes chip clearance in slotting and full-width cuts
• TiN coating improves surface hardness and extends tool life versus uncoated HSS
• 30-degree helix angle with right-hand cut and right-hand flute orientation
• Centercutting design allows direct plunge entry
• Straight-cylindrical shank with Weldon flat for secure tool holding
• HG-2 Series regular-length profile for standard milling center setups

Compatibility

Designed for use with steel, cast iron, and non-ferrous metal workpieces. Compatible with standard end mill holders and set-screw collet systems accepting a 0.75-inch straight shank with Weldon flat.

Installation Notes

Installation is performed by machinists using standard end mill holders or Weldon-flat set-screw tool holders. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify runout with a dial indicator after seating the tool in the holder. Follow the machine tool manufacturer's recommended speeds and feeds for the specific workpiece material and depth of cut.
