Accupro 12177537 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177537 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry. Built from micrograin carbide, it offers a 7-degree taper angle per side with a 1/8 inch small end diameter and a 1/2 inch shank diameter. The 3-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 4 inches overall length with a 1.5 inch length of cut, this tool suits applications where reach and taper accuracy are both critical. It ships uncoated and is center-cutting capable, making it suitable for plunge entry as well as peripheral cuts in carbide-appropriate materials.

This tapered end mill is used in CNC machining centers, vertical mills, and manual knee mills for creating draft angles, tapered slots, mold cavities, and dovetail-style pockets. The square end geometry makes it suitable for flat-bottomed tapered features. Machinists and tooling professionals in mold-and-die, aerospace component, and precision part shops will find this tool applicable to a range of finishing and semi-finishing operations where consistent taper angle is required over a 1.5 inch depth of cut.

Key Features

• 7-degree taper angle per side for consistent draft in mold and cavity work
• Micrograin solid carbide construction for rigidity and edge retention
• 3-flute, right-hand spiral with 30-degree helix angle for balanced chip flow
• Center-cutting capable - supports direct plunge entry
• Uncoated finish suitable for use with cutting fluid in a wide range of workpiece materials
• Square end geometry produces flat-bottomed tapered features

Compatibility

Designed as a standard 1/2 inch shank tapered end mill compatible with R8, CAT, BT, and HSK toolholders and collet chucks accepting 1/2 inch shank diameters on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer or drawbar is de-energized before inserting or removing the tool. Use a properly sized collet or end mill holder rated for the 1/2 inch shank diameter and verify runout with a dial indicator before beginning a cut. Follow machine manufacturer torque guidelines for drawbar and toolholder fasteners.
