Spindle Speed Calculator — Brass C360
Carbide starting RPM for milling Brass C360: n = 1000·Vc/(π·D) with a handbook cutting speed preset.
C360 free-machining brass is the easiest metal in the shop — short, broken chips and almost no built-up edge. Zero-rake or low-rake tools prevent grabbing; speed is limited mostly by spindle and chip evacuation.
Formula
Note: Catalog starting values only — always confirm against your tool maker's data sheet and cut a test part. Machine rigidity, coolant and workholding shift real-world numbers.

Frequently asked questions
What formula does the spindle speed calculator — brass c360 use?+
It evaluates n = 1000·Vc / (π·D), exactly as published. Sources: Machinery's Handbook, 31st ed. — Speeds and Feeds; Sandvik Coromant — Milling formulas & definitions. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
C360 free-machining brass is the easiest metal in the shop — short, broken chips and almost no built-up edge. Catalog starting values only — always confirm against your tool maker's data sheet and cut a test part. Machine rigidity, coolant and workholding shift real-world numbers.
When is this calculator the right tool for the job?+
Carbide starting RPM for milling Brass C360: n = 1000·Vc/(π·D) with a handbook cutting speed preset. A free cnc machining: speeds, feeds & tool wear tool. Zero-rake or low-rake tools prevent grabbing; speed is limited mostly by spindle and chip evacuation. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
