Accupro 12179536 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179536 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.5-inch cutting diameter, a 1.25-inch length of cut, and a 3-inch overall length, this tool delivers consistent material removal in ferrous and non-ferrous metals. The TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life in demanding cutting environments. The 4-flute configuration provides a strong core and a fine surface finish. A 30-degree helix angle balances chip evacuation with cutting stability. Licensed machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users of this end mill.

This end mill is suited for slot milling, profile milling, and step milling in materials such as alloy steel, stainless steel, cast iron, and hardened materials where TiCN coating provides a performance advantage. The 0.5-inch shank diameter fits standard ER and straight-bore toolholders. The regular-length body keeps the tool rigid during high-feed passes. Coarse pitch flute spacing helps clear chips efficiently in deeper cuts. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

Key Features

• 0.5-inch cutting diameter with 1.25-inch length of cut for slot and profile work
• Solid carbide construction for rigidity and dimensional accuracy
• TiCN coating for elevated wear resistance and extended tool life
• 4-flute, coarse pitch design balances chip clearance and finish quality
• 30-degree helix angle for stable cutting and smooth chip flow
• Centercutting geometry supports direct plunge entry
• Right-hand cut, right-hand flute configuration for standard CNC spindle use

Compatibility

Designed as a single-end replacement or production-use square end mill for CNC machining centers and manual mills accepting a 0.5-inch shank diameter straight-bore or collet-style toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank to the minimum recommended engagement depth in the toolholder to avoid runout and premature tool failure. Verify toolholder cleanliness and proper torque on retention knobs or collet nuts before initiating a cut.
