Accupro 12177510 Tapered End Mill 3/16 in Solid Carbide

Product Description

The ACCUPRO 12177510 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper profile. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for hard-material cutting in production and toolroom environments. The small end diameter measures 3/16 inches with a 3-degree taper per side, a 3-inch length of cut, and a 1/2-inch shank diameter. The three-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual mills for tapered slot, draft-angle, and form-milling work.

This end mill suits residential shop and commercial production applications where tapered profiles or draft angles are required on ferrous and non-ferrous workpieces. The square end configuration allows for flat-bottom cuts in addition to tapered wall generation. The uncoated finish makes it well suited for aluminum, brass, and other non-ferrous materials where coatings can cause material adhesion. Its 6-inch overall length provides reach for deeper setups while the 1/2-inch shank ensures secure toolholder engagement in standard ER, Weldon, or shrink-fit holders.

Key Features

• Micrograin solid carbide construction for high edge retention and wear resistance
• 3-degree taper per side for consistent draft-angle and tapered slot milling
• Three-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting capable, allowing plunge entry into the workpiece
• Right-hand flute direction compatible with standard spindle rotation
• Uncoated finish optimized for non-ferrous and softer workpiece materials

Compatibility

Designed as a standard-shank tapered end mill with a 1/2-inch diameter shank, compatible with any CNC or manual milling machine equipped with a 1/2-inch ER collet, Weldon flat holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Power down and lock out the spindle before mounting or removing the end mill. Ensure the shank is fully seated and secured in the toolholder to the recommended engagement depth before beginning any cutting operation. Verify spindle RPM and feed rate are appropriate for the workpiece material and cutting diameter before engaging the cut.
