Value Collection 720-1189 Square End Mill 1 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1189 is a single-end square end mill designed for milling flat surfaces, shoulders, slots, and profiles on ferrous and non-ferrous materials. Built from M2 high speed steel with a bright uncoated finish, it delivers reliable performance in general-purpose machining applications. The 1 inch cutting diameter pairs with a 2.5 inch length of cut and a 30-degree helix angle to support efficient chip evacuation. With two flutes and a spiral flute geometry, this end mill balances rigidity and cutting clearance. It is center-cutting, allowing direct plunge entry into workpieces, and features right-hand cut with right-hand flute direction. Machinists and tool-and-die professionals are the primary users of this tool in manual and CNC milling setups.

This end mill is suited for use in job shops, maintenance machining environments, and production settings where a standard fractional-inch single-end tool is required. The 1 inch shank diameter fits standard ER or end mill holders designed for 1 inch straight shanks. With a 7.25 inch overall length and a 5 inch reach length, it accommodates applications that require extended reach beyond a standard stub or regular-length profile. No coolant-through feature is present, so flood or mist coolant delivery at the machine table is recommended for heat management during extended cuts.

Key Features

• M2 high speed steel construction for durability across a wide range of materials
• 30-degree helix angle promotes smooth cutting action and effective chip evacuation
• Center-cutting design allows direct plunge milling without a pre-drilled hole
• Bright uncoated finish suitable for general-purpose ferrous and non-ferrous applications
• Extended reach at 5 inches accommodates deep-cavity or long-reach milling work
• Two-flute geometry provides maximum chip clearance for slotting and pocketing operations

Compatibility

Designed as a standard fractional-inch single-end square end mill compatible with 1 inch straight-shank end mill holders and collet chucks on vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines for toolholder torque and runout tolerance. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill from the holder. Verify shank engagement depth meets the toolholder minimum grip length before beginning any cut. Use appropriate chip guards and personal protective equipment in accordance with applicable shop safety standards.
