Accupro 12177397 Square End Mill 6 Flute Solid Carbide

Product Description

The ACCUPRO 12177397 is a six-flute solid carbide square end mill designed for high-efficiency milling in demanding machining applications. Built from micrograin carbide, it offers the rigidity and edge retention needed for aggressive material removal at tight tolerances. The 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces across the full 0.5 inch length of cut. At 0.125 inches in diameter with a matching 0.125 inch shank, this end mill is suited for fine-detail slotting, profiling, and contouring work. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills where precision and tool life are priorities.

This end mill is intended for use in both production and job-shop environments where small-diameter, high-flute-count tooling is required. The centercutting geometry allows plunge entry into the workpiece without a pre-drilled hole, expanding its versatility for pocket milling and ramp-entry paths. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC spindle setups. It is well suited for ferrous and non-ferrous materials where micrograin carbide substrate and spiral flute geometry deliver consistent surface finish and dimensional accuracy.

Key Features

• Six-flute spiral design increases contact and improves surface finish at standard feed rates
• 45-degree helix angle for efficient chip evacuation and reduced cutting pressure
• Micrograin solid carbide construction for extended tool life and dimensional stability
• Centercutting capable — supports direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute for compatibility with standard CNC spindle rotation
• Uncoated finish suitable for applications where coating is not required or preferred

Compatibility

Designed as an OEM-style replacement and standard-production square end mill for CNC machining centers and manual milling machines accepting 0.125 inch shank toolholders, collets, and shrink-fit systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet or toolholder to the recommended engagement depth and torque the retention hardware to the toolholder specification. Verify runout with a dial indicator before beginning the first cut to confirm proper seating and avoid premature tool wear or breakage.
