Review on Precision Steel Flute 🔪 Straight Cutter for High-Speed Efficiency by Frankie Wesley

Purchased to make a recess in an aluminum heatsink. I used them on my drill press. not as good as having a proper cutter to break them in. I used one of the larger cutters to countersink and remove most of the material and then cleaned up the edges with a smaller cutter. Very happy with the results
