Robbjack B-333-16 Ball End Mill 0.5in 3 Flute Solid Carbide

Product Description

The ROBBJACK B-333-16 is a single-end, solid carbide ball end mill designed for both roughing and finishing operations on cast iron and non-ferrous metals. It features a 0.5 inch mill diameter with a matching 0.5 inch straight-cylindrical shank, a 1 inch length of cut, and a 3 inch overall length. The three helical flutes are cut at a 30-degree medium helix angle, promoting efficient chip evacuation and stable cutting action. This uncoated Tuffy Grade carbide tool ships as a single-end mill ready for use in CNC machining centers and manual milling setups where precise ball-nose profiling is required.

The B-333-16 suits job shop and production environments handling cast iron components and non-ferrous metal workpieces such as aluminum and copper alloys. Its standard length profile and 1 inch reach length make it practical for contouring, slot milling, and 3D surface work where a full-radius nose is needed. The bright uncoated finish is suited for applications where coating interaction with the workpiece material is a concern or where re-sharpening is anticipated.

Key Features

• Solid carbide construction (Tuffy Grade) for rigidity and wear resistance in cast iron and non-ferrous metals
• Three helical flutes at 30-degree medium helix angle for balanced chip load and smooth finish
• Full ball nose with 0.25 inch nose radius for true hemispherical profiling cuts
• Bright uncoated finish compatible with cast iron (K) and non-ferrous metal (N) material codes
• Single-end design with straight-cylindrical shank for standard collet and end mill holder fitment
• Capable of both roughing and finishing material removal in a single tool

Compatibility

Designed for use in CNC machining centers and manual milling machines that accept a 0.5 inch straight-cylindrical shank. Primary workpiece materials are cast iron (ISO material code K) and non-ferrous metals (ISO material code N). Part of the ROBBJACK Series B-333 standard-length ball end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a properly sized collet or end mill holder to the tool holder manufacturer's specified torque; ensure runout is within acceptable limits before commencing the cut. Power down and lock out the spindle before tool changes. Do not exceed the tool's rated cutting parameters for the workpiece material being machined.
