The Application-Focused Format

R1.5 PCD End Mill — Designed for Strength, Precision, and Longevity

A 1.5 mm corner radius on a PCD-tipped end mill serves two critical functions: it reinforces the cutting edge at its weakest point, and it generates a controlled fillet at the shoulder—eliminating sharp internal stress risers and the need for manual deburring.

Specifications at a Glance

Specification	Detail
Cutting edge material	Polycrystalline diamond, vacuum brazed
Tool body	Solid carbide shank, dynamically balanced
Corner radius	R1.5 mm
Flute configurations	2-flute and 4-flute options available
Surface treatment	None required—diamond is the wear surface
Coolant compatibility	Dry, MQL, or flood coolant all work

The Engineering Behind the Radius

Why add a radius to a cutting tool? Because sharp 90-degree corners are stress concentration points. Under cutting forces, that sharp corner is the first to chip or fracture. Once the corner fails, the entire edge follows. The R1.5 radius distributes these forces across a curved profile, significantly improving impact resistance and abrasive wear tolerance—all while maintaining the ability to produce a square shoulder.

What this means for production: flat floors, clean vertical walls, and a 1.5 mm fillet that extends tool life while improving part strength.

Primary Workpiece Materials

Material Type	Specific Workpieces
Aluminum	6061 billet, 7075 structural, A356 castings, ADC12 die-cast
Copper alloys	Brass fittings, bronze bushings, copper electrodes
Engineering plastics	PEEK components, POM gears, nylon structural parts
Composites	CFRP panels, GFRP laminates, carbon-reinforced parts
Graphite	EDM electrodes, mold cavity roughing

Production Applications

Application Area	Performance Benefit
Mold plate pocket finishing	Radius protects corner during intermittent cuts
Aerospace bracket shoulder milling	Fillet meets print specifications directly
Drone component slotting	Radius minimizes edge chipping on fiber breakout
Large-hole helical boring	Diameter consistency maintained across full depth
Graphite electrode profiling	Radius prevents brittle corner fracture

Performance Metrics
