Accupro 12181563 Square End Mill 0.9843 in 2 Flute Carbide

Product Description

The ACCUPRO 12181563 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.9843-inch (25.00 mm) mill diameter and a 1.4961-inch (38.00 mm) length of cut, this two-flute tool delivers aggressive material removal with strong chip evacuation. The 40-degree helix angle promotes smooth cutting action and reduces vibration during high-speed passes. Built from micrograin solid carbide, the tool holds tight tolerances and maintains edge integrity in demanding applications. It is uncoated and centercutting, allowing plunge and ramp entry. This end mill is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill suits general-purpose milling in ferrous and non-ferrous materials where a large-diameter, two-flute geometry is preferred for chip clearance. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining centers and manual knee mills. The regular-length body and 25.00 mm (0.9843 inch) shank diameter allow direct mounting in standard ER or side-lock tool holders without extensions. Typical applications include slotting, profiling, and peripheral milling in aluminum, brass, steel, and similar machinable alloys.

Key Features

• Micrograin solid carbide construction for extended tool life and edge stability
• 40-degree helix angle reduces cutting forces and improves surface finish
• Centercutting design allows plunge entry and ramp milling without a pilot hole
• Two-flute configuration maximizes chip clearance in slotting and full-width cuts
• Right-hand cut and right-hand flute for standard CNC spindle compatibility
• Uncoated finish suitable for use with cutting fluid in a wide range of materials

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard CNC machining centers and manual mills accepting a 25.00 mm (0.9843 inch) shank diameter in ER collet chucks, Weldon side-lock holders, or equivalent toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the tool holder and torque the retention hardware per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, and confirm speeds and feeds match the material and operation type.
