Accupro 12177441 Tapered End Mill 3/16 in Solid Carbide

Product Description

The ACCUPRO 12177441 is a solid carbide tapered end mill designed for precision milling operations in metalworking and machining applications. It features a 3/16 inch small end diameter with a 0.5 degree taper per side, producing accurately tapered profiles in a single pass. The 3-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers hardness and edge retention well beyond high-speed steel alternatives. The uncoated finish suits applications where coating interaction with the workpiece material is a concern. A licensed machinist or toolroom technician is the typical end user.

This tapered end mill is suited for die and mold work, fixture machining, and contour milling where a precise taper profile is required. The 1-1/4 inch length of cut accommodates moderate-depth tapered pockets and slots. The 1/4 inch shank fits standard collets and end mill holders commonly found in CNC machining centers and manual knee mills. The square end geometry allows flat-bottom cuts. Centercutting capability enables direct plunge entry without a pre-drilled starting hole.

Key Features

• Solid micrograin carbide construction for superior hardness and edge life
• 0.5 degree taper per side for accurate tapered profile milling
• 3-flute right-hand spiral design with 30-degree helix for efficient chip removal
• Centercutting geometry allows direct plunge entry
• Square end for flat-bottom tapered pockets and slots
• Uncoated finish compatible with a wide range of workpiece materials

Compatibility

Designed as a replacement or stock tapered end mill for use in standard 1/4 inch collets and end mill holders on CNC machining centers and manual milling machines requiring a 0.5 degree per side taper profile.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the 1/4 inch shank fully and evenly in the collet or end mill holder and torque the retention hardware per the holder manufacturer specifications. Inspect the cutting edges for chips or damage before mounting, and verify runout with a dial indicator after installation.
