Accupro 14797268 Square End Mill 0.08in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14797268 is a single-end square end mill designed for precision milling in metalworking applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance needed for cutting ferrous and non-ferrous materials at elevated speeds. The cutting diameter is 0.08 inches with a 0.12-inch length of cut and a 2.5-inch overall length. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The extended reach design, with a 0.65-inch reach length, allows access to deeper features without tool interference.

This end mill is suited for finish and semi-finish milling passes in tool-and-die, mold-making, aerospace, and general machining environments where tight tolerances are required. The 1/8-inch shank diameter fits standard collet chucks and tool holders used on CNC machining centers and manual mills. The AlTiN coating extends tool life in dry or semi-dry cutting conditions, making it a practical choice for shops running harder alloy steels, stainless, or titanium. Center-cutting capability allows plunge entry in addition to peripheral and slot milling.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating provides thermal protection and extends tool life in hard materials
• 3-flute, right-hand spiral design with 30-degree helix for effective chip removal
• Center-cutting geometry allows direct plunge entry
• Extended reach with 0.65-inch reach length for deeper feature access
• Tight diameter tolerance of +0.0000 / -0.0010 inches ensures consistent fit and finish

Compatibility

Designed as an OEM-style replacement-grade solid carbide end mill compatible with standard 1/8-inch collet chucks and tool holders on CNC machining centers, knee mills, and similar milling equipment.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully and evenly in the collet to the recommended grip depth to prevent pullout under load. Verify runout with a dial indicator before beginning a cut, as micrograin carbide tools are sensitive to excessive runout and improper clamping.
