Accupro 12177530 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177530 is a solid carbide tapered end mill designed for precision milling operations where controlled wall draft angles are required. Built from micrograin carbide, this tool delivers a 5-degree taper per side with a 1/4 inch small end diameter and a 3/4 inch length of cut. The square end geometry and right-hand spiral fluting make it well suited for profiling tapered pockets, mold cavities, and drafted walls in ferrous and non-ferrous materials. Three flutes provide a balance of chip clearance and cutting edge support. The 30-degree helix angle promotes smooth cutting action and efficient chip evacuation during deep-reach operations.

This end mill is used in CNC machining centers and manual mills for applications that require precise tapered profiles. Typical use cases include die and mold work, aerospace component machining, and precision part manufacturing where draft angles must be held to tight tolerances. The 3/8 inch shank diameter fits standard ER and milling chuck toolholders common in most CNC setups. With a 2-1/2 inch overall length, the tool provides adequate reach for moderate-depth cavity work without excessive overhang.

Key Features

• 5 degrees taper per side for accurate draft angle milling
• Micrograin solid carbide construction for rigidity and wear resistance
• 3 right-hand spiral flutes with 30-degree helix for efficient chip evacuation
• Square end profile suited for flat-bottomed tapered pockets
• Center-cutting capable, allowing plunge entry where required
• Uncoated finish compatible with coolant or dry cutting strategies

Compatibility

Designed as an OEM-style replacement or direct-use tapered end mill for CNC machining centers and manual mills accepting a 3/8 inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the 3/8 inch shank in a properly sized collet or end mill holder, ensuring adequate shank engagement and runout within acceptable limits before operation. Confirm spindle speed and feed rate settings are appropriate for the workpiece material before engaging the cut. Inspect the cutting edges for chips or damage before each use.
