Accupro 118988 Roughing Finishing End Mill 1/2 in Carbide

Product Description

The ACCUPRO 118988 is a single-end roughing and finishing end mill designed for high-efficiency material removal and profile finishing in milling applications. Built from micrograin solid carbide, it offers the rigidity and wear resistance required for demanding cutting operations. The tool measures 0.5 inches in diameter with a 1/2 inch shank and carries a 0.03 inch corner radius across its 3 flutes. With a 37-degree helix angle and right-hand flute direction, it generates efficient chip evacuation during both slotting and peripheral cuts. Weighing 0.2 pounds, it is suited for use in CNC machining centers and manual mills where tool runout and edge stability matter.

The 118988 is intended for pocketing and profiling operations. Its 1-1/8 inch length of cut provides adequate reach for moderate-depth cavities without sacrificing rigidity. The bright, uncoated finish makes it a practical choice for non-ferrous metals and applications where coating compatibility or regrindability is a priority. This end mill belongs to the ACCUPRO AL Series and is a standard choice for machinists and toolroom operators working in job shop or production environments.

Key Features

• Micrograin solid carbide construction for edge rigidity and extended tool life
• 3-flute geometry optimized for pocketing and profiling cuts
• 37-degree helix angle promotes efficient chip evacuation
• 0.03 inch corner radius reduces stress concentration at the cutting edge
• Right-hand cutting direction, single-end design
• Bright, uncoated finish suitable for non-ferrous and general-purpose machining

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 1/2 inch collet or end mill holders in CNC machining centers and manual milling machines requiring a 1/2 inch shank tool.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. The shank should be inserted to the recommended engagement depth in a clean, undamaged collet or end mill holder, and the holder should be torqued per the toolholder manufacturer's specifications. Inspect the corner radius and cutting edges for chips or wear before each use.
