Value Collection 720-3061 Square End Mill 11/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3061 is a single-end square end mill ground from M2 high speed steel and finished bright/uncoated. It carries a 11/16-inch (0.6875-inch) cutting diameter, a 1-5/8-inch (1.6250-inch) length of cut, and a 30-degree helix angle across four right-hand spiral flutes. At 3-3/4 inches overall length with a 5/8-inch shank diameter, it fits standard milling chucks and collet holders used in manual and CNC knee mills. Machinists and tool-and-die technicians reach for this geometry when cutting slots, profiling edges, or stepping down pockets in steel, cast iron, and similar ferrous workpiece materials.

This end mill is suited to general-purpose milling operations in job shops, maintenance departments, and production environments where a reliable fractional-inch HSS cutter is needed without a coated-tool premium. The regular-length body keeps overhang manageable and supports stable cuts at moderate feed rates. Right-hand cutting direction is compatible with conventional spindle rotation on virtually all vertical milling machines and machining centers.

Key Features

• M2 high speed steel construction provides toughness and re-grindability for ferrous materials
• 4-flute, right-hand spiral geometry balances chip evacuation with a strong core
• 30-degree helix angle reduces cutting forces and produces a good surface finish on steel
• Bright/uncoated finish makes tool wear easy to inspect visually
• Single-end design with a 5/8-inch shank fits standard ER and straight-bore toolholders
• Regular-length body (3-3/4 inches OAL) minimizes deflection in general milling setups

Compatibility

Designed as a general-purpose fractional-inch square end mill for use in manual knee mills, vertical machining centers, and similar milling equipment that accept a 5/8-inch straight shank.

Installation Notes

Installation and tooling changes must be performed with the spindle fully stopped and machine power locked out per applicable shop safety procedures. Secure the shank in a clean, properly sized collet or end mill holder and torque the retention hardware to the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning the cut. Center-cutting capability is not present on this tool, so direct plunge entry into solid material is not recommended.
