Accupro 312976 Square End Mill 3/16 in 2 Flute Carbide

Product Description

The ACCUPRO 312976 is a solid carbide square end mill designed for precision milling operations in metal, composites, and plastics. It features a 3/16 inch diameter with a matching 3/16 inch shank, a 5/8 inch length of cut, and a 2-1/2 inch overall length. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces during slotting, profiling, and contouring. Manufactured from micrograin solid carbide, this end mill delivers rigidity and wear resistance that high-speed steel tooling cannot match. The bright, uncoated finish suits general-purpose applications where coating is not required.

This end mill is suited for use in CNC machining centers, manual knee mills, and toolroom applications handling ferrous and non-ferrous materials. Its 2-flute geometry provides adequate flute volume for chip clearance in slotting cuts and light profiling passes. The single-end, regular-length configuration makes it a practical choice for standard depth-of-cut work where extended reach is not needed. Machinists and toolroom operators working in job shops, manufacturing facilities, or maintenance environments will find this a reliable general-purpose cutter.

Key Features

• 3/16 inch diameter solid carbide construction from micrograin carbide substrate for rigidity and edge retention
• 45-degree right-hand helix angle promotes smooth chip flow and reduced cutting force
• 2-flute design provides generous chip clearance for slotting and plunge operations
• Centercutting geometry allows direct plunge entry into workpiece material
• Bright, uncoated finish suitable for general-purpose ferrous and non-ferrous machining
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a general-purpose square end mill fitting any standard collet, end mill holder, or shrink-fit toolholder accepting a 3/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder that matches the 3/16 inch shank diameter to maintain runout within tolerance. Verify tool projection and depth of cut against the 5/8 inch length of cut before beginning any operation.
