3 Flute Diamond Coated Ball End Mills for Graphite

Diamond coating · individual inspection · dimensional report available

3 Flute Diamond Coated Ball End Mills for Graphite currently shows Ø1–12 mm across 59 standard order codes. It combines a fine-grain carbide substrate selected for diamond-deposition compatibility with a ball-nose cutting profile for 3D electrode contours, curved surfaces, ribs, and mould details. The standard-reach form keeps projection compact for rigid, repeatable production machining. Three flutes balance chip evacuation, core strength, and tooth engagement for general graphite profiling.

A diamond system engineered for graphite, 10x longer life

Keeping the spherical cutting edge sharp helps control cusp height and surface consistency as the tool follows changing contact points. The standard-reach form keeps projection compact for rigid, repeatable production machining.

3F Diamond Ball Nose diamond coating interface on carbide substrate

Dense coating with a secure interface

Substrate chemistry and microstructure promote diamond nucleation, reducing the risk of premature coating separation on the 3DBE series during abrasive cutting.

3F Diamond Ball Nose diamond coating versus TiAlN edge wear after 60 minutes

About 74% less edge retreat after 60 minutes

The shown carbon-resin test records about 0.006 mm edge retreat for diamond coating versus 0.023 mm for TiAlN. For this ball-nose cutting profile for 3D electrode contours, curved surfaces, ribs, and mould details, lower wear supports more consistent profile retention.

3F Diamond Ball Nose cutting data selector

Choose cutter diameter, then select the applicable reach or taper combination to view spindle speed, feed rate, axial depth ap, and radial width ae. Use the result as a test-cut starting point and optimise for machine rigidity, actual overhang, runout, and graphite grade.

Select cutting condition

Use the selection to establish first-piece test-cut settings; final values depend on the machine and setup.

Recommended operations

Balanced chip evacuation, rigidity, and finish in 3D electrode work.

Selection notes

  • 3-flute geometry: greater tooth engagement for stability and finish in high-speed finishing.
  • Use the shortest safe projection to maximise rigidity.
  • Machine graphite dry with effective vacuum extraction; validate parameters for the graphite grade and CNC setup.

Rigidity and handling

Extreme hardness also means brittleness. Use a rigid CNC, precision holder, and secure workholding; control runout especially on long-reach and small-diameter tools, and avoid impact entry.

Verified dimensions on every end mill

ZOLLER optical measurement of 3F Diamond Ball Nose graphite end mills

ZOLLER inspection for every 3DBE end mill

Ball-profile radius, cutter diameter, runout, and the transition into the flute are checked for predictable 3D finishing. A dimensional report can be supplied with the order for acceptance and traceability.

  • Default cutter diameter tolerance: -0.020 / 0 mm
  • Default cutter corner-radius tolerance: ±0.02 mm
  • Dimensional report available for order acceptance and traceability

Built for abrasive graphite, carbon fiber, and fiberglass

The 3DBE series uses a ball-nose cutting profile for 3D electrode contours, curved surfaces, ribs, and mould details. Its diamond-coated carbide edge is designed for graphite electrodes and, after application validation, abrasive non-metals such as CFRP and GFRP.

For abrasive composite profiling, the rounded end supports contour following; confirm laminate support and entry strategy to control delamination.
