Accupro 12181195 Square End Mill 1 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181195 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. It features a 1-inch mill diameter, a 1.5-inch length of cut, and a 6-inch overall length, placing it in the long-reach category with a 4.25-inch reach length. The 40-degree helix angle and TiCN (Titanium Carbonitride) finish contribute to improved chip evacuation and surface hardness. Manufactured from micrograin carbide, this end mill is built for tight-tolerance work where tool deflection and edge wear are primary concerns. It is centercutting and suitable for plunge operations.

This end mill is intended for professional machinists and toolroom applications requiring extended reach into deep pockets, slots, or stepped features. The right-hand cut and right-hand spiral flute configuration is the standard orientation for CNC vertical machining centers and manual knee mills. The 1-inch shank diameter provides solid tool holding rigidity in standard ER or side-lock holders. Its long-reach geometry makes it well suited for aerospace, die and mold, and general metalworking operations where standard-length tools cannot reach the workpiece feature.

Key Features

• 1-inch mill diameter with micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating increases surface hardness and reduces built-up edge in ferrous materials
• 40-degree helix angle promotes aggressive chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry into workpiece material
• Extended reach with 4.25-inch reach length for deep-pocket and step-milling applications
• Right-hand cut, right-hand flute — standard orientation for CNC and manual milling setups

Compatibility

Designed as an OEM-style cutting tool for use in standard 1-inch bore milling chucks, collet holders, or side-lock tool holders on CNC vertical machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips or debris before seating the shank. Verify runout with a dial indicator after tool installation to confirm concentricity within acceptable limits. Follow the machine tool manufacturer's recommended speeds and feeds for solid carbide end mills in the specific workpiece material.
