2 Flute Diamond Coated Square End Mills for Graphite

Diamond coating · individual inspection · dimensional report available

2 Flute Diamond Coated Square End Mills for Graphite currently shows Ø0.2–12 mm across 63 standard order codes. It combines a fine-grain carbide substrate selected for diamond-deposition compatibility with a square-end geometry for flat pocket floors, slots, shoulders, side walls, and edge milling. The standard-reach form keeps projection compact for rigid, repeatable production machining. Two open flutes provide generous chip space for slotting, roughing, and small-diameter cutting.

A diamond system engineered for graphite, 10x longer life

Wear control at the peripheral edge and end teeth helps retain floor flatness, wall size, and a clean 90-degree feature transition. The standard-reach form keeps projection compact for rigid, repeatable production machining.

2F Diamond Square End 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 2DEM series during abrasive cutting.

2F Diamond Square End 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 square-end geometry for flat pocket floors, slots, shoulders, side walls, and edge milling, lower wear supports more consistent profile retention.

2F Diamond Square End 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

Plunge-capable slots, pockets, edges, and roughing with open chip space.

Selection notes

  • 2-flute geometry: more chip space for slotting, roughing, and higher-volume removal.
  • 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 2F Diamond Square End graphite end mills

ZOLLER inspection for every 2DEM end mill

Cutter diameter, end-face geometry, runout, and cutting-edge condition are checked to support accurate slots, walls, and pocket floors. 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 2DEM series uses a square-end geometry for flat pocket floors, slots, shoulders, side walls, and edge milling. Its diamond-coated carbide edge is designed for graphite electrodes and, after application validation, abrasive non-metals such as CFRP and GFRP.

Square ends can machine abrasive composite edges and pockets where a flat floor is required; select entry and support to limit fibre breakout.
