Accupro 40671372 Indexable Chamfer Face Mill 3 Inch

Product Description

The ACCUPRO 40671372 is an indexable chamfer angle face mill designed for precision milling operations on metalworking machining centers and milling machines. It carries a 45-degree lead angle and accommodates 6 indexable inserts held in place by screws, delivering consistent chamfering and face milling performance. The cutter spans a minimum cutting diameter of 3 inches up to a maximum of 3.3544 inches, with a maximum depth of cut of 0.1300 inches. The arbor hole diameter is 1 inch, making it compatible with standard horizontal and vertical milling setups. This tool is installed and operated by machinists and toolroom professionals working in production or job-shop environments.

This face mill is suited for right-hand cutting applications in ferrous and non-ferrous machining operations where chamfering and face milling are performed in a single pass. The Series CI cutter style ADSM configuration features a negative radial and positive axial rake geometry, which supports controlled chip formation and insert longevity. Coolant-through capability allows for effective heat management during heavier cuts. The 2-inch overall height and 2.2835-inch hub diameter suit mid-size milling arbor setups commonly found in production shops.

Key Features

• 45-degree lead angle for combined chamfering and face milling in one operation
• 6-insert capacity with screw-lock holding method for secure, repeatable indexing
• Negative radial and positive axial rake geometry for controlled chip evacuation
• Coolant-through design to manage heat during extended cuts
• Right-hand cutting direction compatible with standard spindle rotation
• Compatible insert size code 08 accepts HNKU 4.542AZER and HOKU 4.542AZER inserts

Compatibility

Compatible inserts are HNKU 4.542AZER and HOKU 4.542AZER, size code 08. The 1-inch arbor hole with a 0.3840-inch keyway width fits standard milling arbors of that bore size. Verify spindle and arbor specifications before mounting.

Installation Notes

Installation should be performed by a qualified machinist following standard machine tool lockout and tagout procedures before mounting or removing the cutter. Confirm arbor bore, keyway dimensions, and spindle direction match this tool before installation. Use proper torque procedures per insert manufacturer guidelines when seating indexable inserts, and inspect insert seating surfaces for debris before each use. Always verify depth-of-cut and feed rate parameters against the machine tool capacity before initiating a cut.
