Accupro 12181605 Square End Mill 0.1772 in 2 Flute Carbide

Product Description

The ACCUPRO 12181605 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 0.1772 inch (4.50 mm) diameter with a 0.374 inch (9.50 mm) length of cut and a 6.00 mm shank diameter. The micrograin carbide construction provides rigidity and edge retention at small diameters. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This stub-length end mill is sized for applications where tool deflection must be minimized and where reach into deep cavities is not required. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where a small-diameter, center-cutting tool is needed. The uncoated micrograin carbide construction makes it appropriate for dry or wet cutting in aluminum, brass, and mild steels. Its stub-length configuration reduces overhang and improves rigidity on vertical machining centers and CNC mills. Right-hand cut and right-hand spiral flute geometry follow standard toolholder conventions, making setup straightforward on most spindle configurations.

Key Features

• 0.1772 inch (4.50 mm) diameter with mill diameter tolerance of +0.000 / -0.002 inches for consistent sizing
• Solid micrograin carbide construction for improved hardness and edge retention at small diameters
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• Center-cutting design allows direct plunge entry without pre-drilling
• Stub-length configuration minimizes deflection for improved dimensional accuracy
• Right-hand cut, right-hand spiral flute geometry compatible with standard CNC mill spindle direction

Compatibility

Designed as a standard square end mill for use in CNC machining centers and manual milling machines accepting a 6.00 mm shank diameter. Confirm collet or toolholder bore size before installation.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully within the collet or toolholder to the recommended grip length to prevent pullout under cutting loads. Do not exceed the recommended depth of cut or feed rate for the tool diameter, as small-diameter carbide end mills are susceptible to breakage under excessive load.
