The TrueFlat 1.75″ Surfacing Bit is designed to quickly flatten spoilboards, slabs, and end grain panels so your CNC projects start perfectly flat. Its replaceable carbide inserts deliver a clean surface while lasting far longer than traditional carbide-tipped surfacing bits. The 1.75″ cutting diameter with a .50″ shank removes material quickly and provides excellent stability on both hobby and professional CNC routers. Recommended Feeds & Speeds Hobby CNC with Router - 60 IPM Hobby CNC with Spindle - 100 IPM Industrial CNC - 300 IPM Cut Depth Per Pass - .125" - .25" RPM's - 18,000 Plunge Rate = 50% of Feedrate (ex: Feedrate=100 IPM, Plunge Rate=50 IPM) These Feedrates are recommended starting points, each CNC is different and feedrates will vary.
