Accupro 12185136 Square End Mill 11/32 in 4 Flute Altin

Product Description

The ACCUPRO 12185136 is a double-end, four-flute square end mill designed for precision milling in demanding metalworking applications. Manufactured from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers high hardness and heat resistance at elevated cutting speeds. The 11/32-inch (0.3438-inch) cutting diameter and 3/4-inch length of cut suit it for slotting, profiling, and peripheral milling operations. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals working in job shops, production facilities, and maintenance environments will find this end mill suited to ferrous and hard alloy workpieces.

This end mill is appropriate for use on CNC machining centers and manual knee mills where right-hand cutting and right-hand flute direction are required. The double-end configuration provides two usable cutting ends, extending tool life per unit. The 3/8-inch shank diameter fits standard collets and tool holders common in both R8 and CAT/BT tooling systems. It is well suited to finishing and semi-finishing passes in steel, stainless steel, and high-temperature alloys where AlTiN coating performance is an advantage.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating provides oxidation resistance and extended tool life in ferrous materials
• 40-degree helix angle improves chip flow and reduces cutting forces
• Double-end design yields two cutting ends per tool
• Centercutting geometry allows plunge entry as well as peripheral cuts
• Right-hand cut, right-hand spiral flute configuration for standard CNC and manual mill setups

Compatibility

Designed as a standard-shank replacement or stock end mill for CNC machining centers and manual mills accepting a 3/8-inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the minimum insertion depth recommended by the toolholder manufacturer to prevent runout and pullout. Verify shank diameter tolerance compatibility with the holder before tightening.
