Drilling Speed & Feed — Copper C110
HSS drill RPM, feed and time-per-hole for Copper C110 from handbook cutting data.
Copper grabs drills like brass but with stringy chips: a slight lip flat plus frequent pecks beats both demons. Expect oversize holes (~+1%) unless the drill is dead sharp and short.

About Drilling Speed & Feed — Copper C110
Drilling Speed & Feed — Copper C110 computes the governing relationship n = 1000·Vc/(π·D) · vf = n·fr · t = depth/vf live as you type. Copper grabs drills like brass but with stringy chips: a slight lip flat plus frequent pecks beats both demons. Expect oversize holes (~+1%) unless the drill is dead sharp and short. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Drilling Speed & Feed — Copper C110
- 1Enter your values — Drill diameter D, Cutting speed Vc, Feed per rev, Hole depth (sensible defaults are pre-filled).
- 2Read the live results: Spindle speed, Plunge feed, Time per hole.
- 3Check the "with your numbers" line to see n = 1000·Vc/(π·D) · vf = n·fr · t = depth/vf substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Drilling Speed & Feed — Copper C110?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula n = 1000·Vc/(π·D) · vf = n·fr · t = depth/vf with authoritative sources cited on the page (Machinery's Handbook, 31st ed. — Speeds and Feeds; Kalpakjian & Schmid, Manufacturing Engineering and Technology, 7th ed., ch. 21)
- ✓Copper grabs drills like brass but with stringy chips: a slight lip flat plus frequent pecks beats both demons.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the drilling speed & feed — copper c110 use?+
It evaluates n = 1000·Vc/(π·D) · vf = n·fr · t = depth/vf, exactly as published. Sources: Machinery's Handbook, 31st ed. — Speeds and Feeds; Kalpakjian & Schmid, Manufacturing Engineering and Technology, 7th ed., ch. 21. 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?+
Copper grabs drills like brass but with stringy chips: a slight lip flat plus frequent pecks beats both demons. 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?+
HSS drill RPM, feed and time-per-hole for Copper C110 from handbook cutting data. A free cnc machining: speeds, feeds & tool wear tool. Expect oversize holes (~+1%) unless the drill is dead sharp and short. 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.
