Value Collection 720-1253 Square End Mill 1 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1253 is a single-end square end mill designed for material removal and profile milling in metalworking applications. Built from M2 high speed steel with a bright uncoated finish, it runs a 1 inch cutting diameter with a 2.5 inch length of cut and a 30-degree helix angle. The two-flute spiral configuration promotes chip evacuation and suits slotting, peripheral milling, and plunge cutting operations. Right-hand cut and right-hand flute geometry follow standard milling conventions. The 1 inch shank diameter matches common collet and end mill holder sizes found in CNC machining centers and manual knee mills alike.

This end mill is suited for shops running general-purpose milling on steel, stainless steel, cast iron, and aluminum or other non-ferrous materials. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole, making it practical for die work, pocket milling, and step machining. The regular-length body keeps the tool rigid under cutting loads, reducing deflection in typical depth-of-cut passes. It is a practical choice for job shops, tool rooms, and maintenance machining environments where a reliable uncoated HSS end mill is needed for mixed-material work.

Key Features

• M2 high speed steel construction provides toughness and re-sharpenability across a range of workpiece materials
• Centercutting design allows direct plunge entry without a pilot hole
• 30-degree helix angle promotes smooth cutting action and chip flow on steel and non-ferrous materials
• Bright uncoated finish suited for use with cutting fluid and compatible with regrinding services
• Right-hand cut and right-hand flute geometry match standard spindle rotation on conventional milling equipment
• Regular-length body with 1 inch shank for rigid tool holding in collets and shell mill adapters

Compatibility

Designed for use with standard 1 inch collets, end mill holders, and Weldon-style tool holders on CNC machining centers and manual milling machines. Rated for primary workpiece materials including steel, stainless steel, cast iron, and aluminum and non-ferrous materials per material codes P, M, K, and N.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in an e-stop or locked-out state per OSHA lockout/tagout procedures. Verify shank seating depth and holder runout before cutting, as excessive runout accelerates edge wear on HSS tooling. Torque the drawbar or set screw to the tool holder specification and confirm tool projection matches the programmed depth of cut before starting the spindle.
