Accupro 40280216 Indexable Chamfer Angle Face Mill

Product Description

The ACCUPRO 40280216 is an indexable chamfer angle face mill designed for precision chamfering and face milling operations on machining centers and milling machines. Built on the CI series platform with a 45-degree lead angle, this cutter handles negative radial and positive axial rake geometries using a 4-insert configuration. The arbor hole diameter is 0.5 inches, and the tool accepts size 08 inserts secured by screw-clamp holding. Coolant-through capability supports chip evacuation and tool life in demanding cuts. The body is machined from steel for rigidity under interrupted and continuous cutting conditions.

This face mill suits shops performing chamfer preparation, edge breaking, and light face milling on ferrous and non-ferrous workpieces. The right-hand cutting direction and ADSM cutter style make it compatible with standard right-hand spindle setups. With a minimum cutting diameter of 1.5 inches and a maximum cutting diameter of 1.8544 inches, it fits tooling setups where a compact-diameter shell mill arbor is used. The maximum depth of cut is 0.13 inches per pass, positioning this cutter for finishing and semi-finishing chamfer work rather than heavy roughing.

Key Features

• 45-degree lead angle for consistent chamfer geometry on part edges
• 4-insert capacity with screw-clamp holding for repeatable insert indexing
• Coolant-through design aids chip removal and extends insert life
• Negative radial and positive axial rake reduces cutting forces on the workpiece
• 0.5-inch arbor hole with 0.2657-inch keyway width for positive drive engagement
• Steel toolholder body provides stiffness for chatter-free chamfering cuts

Compatibility

Compatible inserts are HNKU 4.542AZER and HOKU 4.542AZER, size code 08. The cutter mounts on a 0.5-inch arbor. Verify hub diameter of 1.496 inches and overall height of 1.5 inches against your toolholder and machine spindle clearance before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling specialist. Power down and lock out the machine spindle before mounting or removing the cutter body or indexing inserts. Torque the insert screws and arbor retention hardware according to the toolholder manufacturer specifications using calibrated tooling — do not substitute generic fastener torque values. Verify runout with a dial indicator after mounting and before initiating a cut.
