Carbide Corner Radius End Mill Internal R Cutter Round Corner Grooving for Mold CNC Machining

Dovetail cutter — tested on 6061-T6 at 200 m/min, 0.05 mm/rev. Clean cut, no tear, no chatter. Edge geometry is precise, dimensional accuracy was plus-minus 0.01 mm on the dovetail angle. 5 stars for slide-fit work.

Chamfer mill for production. 45 degree chamfer and 60 degree chamfer, different sizes. Consistent geometry across the batch, sharp out of the box, no chatter. 5 stars for production chamfering.

Carbide dovetail cutter for slide-fit details. We use these on aluminum extrusion dies and steel machine slides. Geometry is correct, the back-clearance is right, sharp out of the box. Bought 8 in different sizes for our die shop. Excellent.

Spotting / chamfer mill. We use these on every job — for spotting before drilling, for chamfering edges, for deburring. Center-cutting geometry, sharp tip, runs in aluminum and steel both. Solid tool. 5 stars.

Inner-R radius cutter for filleted corners. We machine a lot of small R details in injection molds and these come in every radius from R0.5 to R6.0. Sharp out of the box, repeatable geometry, no chipping at the edge. Good tool. 5 stars.
