Value Collection 720-3123 Square End Mill 1-1/4 in 6 Flute Hss

Product Description

The VALUE COLLECTION 720-3123 is a single-end square end mill designed for milling flat surfaces, slots, and shoulders on metalworking machines. Made from M2 high speed steel with a bright uncoated finish, this tool handles general-purpose milling operations in ferrous and non-ferrous materials. It features 6 right-hand spiral flutes with a 30-degree helix angle and is configured for right-hand cutting. The 1-1/4 inch cutting diameter and 2 inch length of cut make it well suited for moderate depth-of-cut applications. Machinists, toolroom operators, and CNC mill programmers will recognize this as a standard fractional-inch geometry end mill built to the VC-HSS-6 series spec.

This end mill fits conventional vertical mills, knee mills, and CNC machining centers that accept a 1 inch straight shank. The 4-1/2 inch overall length falls within the regular length category, providing good rigidity during side milling and slotting. It is appropriate for production shops, toolrooms, and maintenance machining where a general-purpose HSS end mill is preferred over carbide. This tool is not center-cutting and is not rated for plunge operations.

Key Features

• M2 high speed steel construction for toughness and re-sharpenability
• 6 right-hand spiral flutes with 30-degree helix angle for improved chip evacuation
• Bright uncoated finish suitable for a wide range of base materials
• Single-end configuration with 1-1/4 inch cutting diameter and 2 inch length of cut
• 1 inch straight shank fits standard ER and shell mill holders accepting that bore
• Non-center-cutting geometry — designed for peripheral and slot milling, not plunge entry

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for vertical mills, knee mills, and CNC machining centers that accept a 1 inch diameter straight shank end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before seating or removing the tool from the holder. Verify collet or end mill holder bore matches the 1 inch shank diameter before tightening. Follow your machine tool manufacturer torque specifications for the holder style in use, and confirm runout with a dial indicator before beginning a cut.
