Accupro 12177489 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177489 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper profile. It features a 1/4 inch small end diameter, a 2-1/4 inch length of cut, and a 2-degree taper angle per side. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The micrograin carbide construction delivers hardness and wear resistance suited to demanding ferrous and non-ferrous machining applications. The uncoated finish makes this tool a reliable baseline option for shops that apply their own coatings or work in materials where coating adhesion is a factor.

This end mill is used in CNC machining centers and manual mills for producing tapered slots, draft angles, and cavity work in mold and die applications as well as general production machining. The square end geometry supports flat-bottom cuts. Right-hand flute direction and center-cutting capability allow both plunge and peripheral cutting. The 7/16 inch shank diameter and 4 inch overall length suit standard ER and end mill holders commonly found in vertical machining center setups.

Key Features

• 2-degree taper angle per side for precise draft and taper profile control
• Micrograin solid carbide construction for hardness and edge retention
• 3 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows direct plunge entry
• Right-hand cut, right-hand flute configuration compatible with standard spindle rotation
• Uncoated finish suitable for re-coating or use in applications where coatings are not required

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers and manual mills accepting a 7/16 inch shank diameter in standard end mill or collet-style toolholders.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the 7/16 inch shank in a properly sized collet or end mill holder, ensuring adequate engagement length and runout within machine tolerances. Inspect the cutting edges for chips or damage before mounting. Power down and lock out the spindle before changing tooling per standard shop safety practice.
