Accupro 14981786 3/16 Inch 4-flute Carbide Square End Mill

Product Description

The ACCUPRO 14981786 is a solid carbide square end mill designed for precision milling operations in steel and other ferrous workpiece materials. Built to fractional inch standards, it features a 3/16 inch (0.1875 inch) mill diameter and a 5/8 inch length of cut, making it well suited for slotting, profiling, and peripheral milling in tight-tolerance applications. The four-flute, right-hand spiral geometry promotes efficient chip evacuation while maintaining surface finish quality. A diamond-like carbon (DLC) coating reduces friction and heat buildup at the cutting edge, extending tool life in demanding steel-cutting environments. At 2.0 inches overall length, this is a regular-length, single-end tool intended for use in CNC machining centers and manual mills.

This end mill is targeted at machinists and tool-and-die professionals working in job shops, production facilities, and maintenance departments. The 3/16 inch diameter and regular length make it a practical choice for fine-detail work, narrow slot milling, and contour profiling in steel components. The straight shank is compatible with standard collet chucks and end mill holders sized for 3/16 inch shank diameter. Center-cutting capability allows plunge entry without a pre-drilled pilot hole, adding versatility to the setup.

Key Features

• Solid carbide construction provides rigidity and wear resistance in steel-cutting applications
• DLC (diamond-like carbon) coating reduces friction and extends cutting edge life
• Four right-hand spiral flutes promote efficient chip evacuation and consistent surface finish
• Center-cutting design allows direct plunge milling without a pilot hole
• 30-degree helix angle balances cutting force and chip flow in ferrous materials
• Single-end, straight shank fits standard 3/16 inch collet chucks and end mill holders

Compatibility

Designed as an OEM-style replacement and standard fractional-inch tooling option for CNC machining centers and manual mills using 3/16 inch straight-shank end mill holders or collet chucks. Primary workpiece material designation is steel (ISO material code P).

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before torquing the retention hardware. Verify runout with a dial indicator after clamping to confirm proper seating before initiating a cut.
