Precision circuit board drill No 80

The M.A. Ford Twister GP drill bit carries part number 30201350 and is sized as a No 80 tool for creating very small holes in printed circuit boards. It is intended for electronics technicians, prototype builders and repair specialists who need accurate micro-drilling capability in a new, unused accessory.

Low heat and minimal vibration in hand-held use

The Twister GP geometry reduces friction so the bit runs cool during normal drilling cycles and produces little audible noise when driven by a standard rotary tool. Power draw stays modest because the cutting edges shear cleanly through fibreglass laminate without excessive load on the motor.

Supplied as a single bare bit with no extras

No collet, holder, lubricant or software is bundled with the 30201350, so users must provide their own compatible chuck and any desired coolant. The California Proposition 65 notice indicates the product contains a chemical known to the state to cause cancer and reproductive harm, requiring appropriate handling precautions.

Questions about this item

How do I install the No 80 Twister GP drill in a drill press and what step is often missed?

Chuck the 30201350 shank fully and tighten the jaws evenly; the step many skip is verifying true run-out with a dial indicator before cutting.

What maintenance or replacement will the No 80 circuit board drill need over time?

The cutting edges dull with use; plan to resharpen or replace the drill once hole quality drops or feed force rises noticeably.

What limit appears first on the No 80 drill during sustained drilling in fibreglass boards?

Heat buildup at the point is the first limiting factor; peck drilling and air blast keep temperatures manageable.
