Accupro 31683857 Double Angle Milling Cutter 90 Deg

Product Description

The ACCUPRO 31683857 is a double angle milling cutter designed for precision V-groove, chamfer, and angular milling operations on CNC machining centers and manual mills. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, it delivers extended tool life in ferrous and hardened materials. The 90-degree included angle, 3/8 inch cut diameter, and 1/8 inch cutting width make it well suited for tight-tolerance angular features. Six teeth provide a balance of chip clearance and surface finish. The overall length of 4 inches with a 2-3/4 inch neck length allows access to recessed features without interference.

This cutter is used in metalworking applications requiring accurate angular cuts, chamfers, dovetail preparation, or deburring passes. The 3/8 inch shank diameter fits standard ER and straight-bore toolholders common in CNC milling setups. The 1/4 inch neck diameter and extended neck length of 2-3/4 inches allow clearance in deeper pockets or stepped workpiece features. Machinists in job shops, tool rooms, and production environments install this type of cutter for both prototype and production runs on steel, stainless, cast iron, and similar materials where AlTiN coatings perform well.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating extends tool life in ferrous and hardened workpiece materials
• 90-degree included angle for standard chamfers and V-groove profiles
• 6-flute design balances chip evacuation with surface finish quality
• Extended 2-3/4 inch neck length provides clearance for recessed features
• 3/8 inch shank fits standard ER collet and straight-bore toolholders

Compatibility

Designed for use with standard 3/8 inch straight-bore or ER collet toolholders on CNC machining centers and manual knee mills performing angular milling, chamfering, and V-groove operations.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Ensure the toolholder bore and collet are clean and free of debris before seating the shank. Follow machine tool manufacturer torque specifications for drawbar and collet nut tightening. Confirm spindle speed and feed rate parameters are appropriate for the workpiece material and cutter diameter before engaging the cut.
