Harvey Tool 16031 Back Corner Rounding End Mill 3-flute

Product Description

The HARVEY TOOL 16031 is a solid carbide back corner rounding end mill designed to cut concave radii on the back edges of workpieces. With a 1/32 inch (0.0310 inch) radius and a 3/16 inch mill diameter, it produces clean, consistent corner breaks in a single pass. The 3-flute geometry provides a balance of chip clearance and surface finish suited to ferrous and non-ferrous materials. This is a single-end tool with a right-hand cut and right-hand flute direction, standard in CNC milling applications. Machinists and tool-and-die professionals install this type of end mill in vertical machining centers or manual mills where back-edge deburring and radius forming are required.

Back corner rounding end mills like the 16031 are used in precision machining shops handling parts that require a defined concave radius on rear-facing edges — a feature that cannot be reached with conventional corner rounding tools. Typical applications include deburring, edge prep, and radius forming on components machined from steel, aluminum, brass, and similar machinable alloys. The uncoated bright finish makes it suitable for use across a range of materials without coating compatibility concerns.

Key Features

• 1/32 inch radius (0.0310 inch) for precise back-edge concave corner forming
• 3/16 inch mill diameter with matching 3/16 inch shank for direct collet mounting
• 3-flute design balances chip evacuation and surface finish quality
• Solid carbide construction provides rigidity and wear resistance over high-speed runs
• Right-hand cut and right-hand flute direction — standard CNC spindle compatibility
• Uncoated bright finish suits a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC vertical machining centers and manual milling machines accepting a 3/16 inch shank collet or tool holder.

Installation Notes

This end mill is installed and serviced by machinists and CNC operators. Always power down and lock out the spindle before changing tooling. Secure the 3/16 inch shank fully in a matching collet or end mill holder to the holder manufacturer's specified clamping procedure. Verify spindle speed and feed rate are appropriate for the workpiece material and tool diameter before initiating a cut.
