Harvey Tool 978145-C3 Chamfer Mill 3/16 in 3 Flute Solid Carbide

Product Description

The HARVEY TOOL 978145-C3 is a solid carbide chamfer mill designed for precise chamfering, deburring, and edge-breaking operations on metal workpieces. With a 3/16 inch cutter head diameter and a right-hand cutting direction, this tool delivers clean, consistent angled cuts on ferrous and non-ferrous materials. The AlTiN coating provides elevated heat resistance and surface hardness, extending tool life during high-speed or dry cutting applications. Three flutes balance chip evacuation with edge strength, making this an efficient choice for production environments and short-run jobs alike. Machinists and CNC operators in tool-and-die, aerospace, and general metalworking shops are the primary users of this tool.

This chamfer mill is suited for use in CNC machining centers and manual mills where consistent chamfer geometry is required on tight-tolerance parts. Its compact 3/16 inch diameter makes it well-suited for small-feature work, narrow slots, and holes where larger-diameter tools cannot reach. The AlTiN coating performs well in hard-material applications and elevated-temperature cutting environments. With a 2 inch overall length and a 3/16 inch shank diameter, it fits standard collet systems without the need for adapters in most setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in metal-cutting applications
• AlTiN coating for extended tool life and performance in dry or high-speed cutting
• 3 flutes for efficient chip removal and clean chamfer finish
• Right-hand cutting direction for standard CNC spindle compatibility
• Compact 3/16 inch diameter for small-feature and tight-clearance work
• 0.074 inch length of cut for controlled chamfer depth per pass

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 3/16 inch collet or toolholder. Verify spindle compatibility and collet size before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the machine is in a safe state before loading or changing tooling. Seat the shank fully in the collet and torque the collet nut to the toolholder manufacturer's specification. Inspect the cutting edges for chips or damage before use, and confirm runout is within acceptable tolerances for the application.
