Value Collection 720-1129 Square End Mill 1-3/8 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1129 is a single-end square end mill designed for milling flat surfaces, shoulders, slots, and profiles in metal workpieces. Manufactured from M2 high speed steel with a bright uncoated finish, it measures 1.375 inches in diameter with a 1.625-inch length of cut and a 0.750-inch shank diameter. The 2-flute, right-hand spiral geometry with a 30-degree helix angle promotes chip evacuation and cutting efficiency. This tool is center-cutting, allowing it to plunge directly into material. Machinists and tool-and-die professionals install this end mill in conventional vertical or horizontal milling machines, CNC machining centers, and manual knee mills.

This end mill is suited for roughing and finishing operations in steel, stainless steel, cast iron, and aluminum and non-ferrous materials. Its regular-length design keeps it rigid for general-purpose work where extended reach is not required. Typical applications include face milling, slot milling, and step cutting in production and job-shop environments. The fractional-inch shank fits standard collets and end mill holders sized for 3/4-inch shanks.

Key Features

• M2 high speed steel construction provides good wear resistance and toughness across a range of workpiece materials
• 2-flute right-hand spiral design with 30-degree helix angle supports chip flow and reduces heat buildup
• Center-cutting geometry allows direct plunge entry without a pre-drilled hole
• Bright uncoated finish suitable for use with or without cutting fluid
• Single-end design with a 3/4-inch shank for secure holder engagement
• Right-hand cutting direction compatible with standard spindle rotation on most milling equipment

Compatibility

Designed as an OEM-style replacement or direct-fit end mill for milling machines and machining centers that accept a 3/4-inch shank end mill holder or collet in fractional-inch sizing.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the milling machine spindle is fully stopped and power is locked out before inserting or removing the end mill from the holder. Verify the shank is fully seated and the set screw or collet nut is torqued per the holder manufacturer's specification. Inspect the cutting edges for damage before each use and confirm proper work-holding before initiating the cut.
