Compare PCB tool families
Select the family by the operation, then check the required diameter, working length and machine setup. The dimensions below are catalogue references, not a live inventory or a statement that every size and length combination is available.
| Tool family | Catalogue diameter | Shank | Selection detail |
|---|---|---|---|
| Standard PCB drill bits | 0.075–3.175 mm | 3.175 mm | Match flute length to diameter and board stack. |
| Undercut PCB drill bits | 0.25–1.20 mm | 3.175 mm | Compare cutting section and reduced body geometry. |
| PCB slot drill bits | 0.40–3.00 mm | 3.175 mm | Confirm the slot and intended machining cycle. |
| PCB router bits | Confirm at enquiry | Confirm at enquiry | Specify material, profile, thickness and edge requirements. |
What to include in a PCB tooling enquiry
Send the board material, tool diameter, flute length, shank and overall length, machine or operation, and quantity. An existing tool drawing or reference helps resolve differences between similarly named tools.
Frequently asked questions
Can I choose a PCB drill by diameter alone?
No. Diameter should be specified together with flute length, shank, overall length and the application. Use our PCB drill dimensions guide to prepare the details.
Are catalogue dimensions the same as stock availability?
No. Product pages describe catalogue tool families. Exact supply dimensions, quantities and lead time are confirmed in the quotation.
How do I choose standard or undercut drills?
Compare the full tool geometry and your existing process. Our standard versus undercut guide explains what to check without assuming one family suits every board.
