Twister GP Circuit Board Drill No 84

The M.A. Ford Twister GP Circuit Board Drill No 84 is a precision cutting tool designed for drilling printed circuit boards. It serves electronics technicians, prototype engineers and maintenance crews who need clean, accurate holes in composite board materials. The drill is supplied new and identified by part number 30201150.

Sustained drilling performance

The Twister GP geometry is engineered to maintain cutting efficiency during extended drilling sessions on abrasive glass-epoxy substrates. Its flute design promotes consistent chip evacuation, reducing heat buildup that can degrade edge quality over long production runs. Stable performance helps operators hold tight tolerances across multiple panels without frequent tool changes.

Practical limits of the drill interface

The No 84 designation defines the specific diameter this tool produces, setting a fixed hole size that cannot be adjusted. Users requiring different via or component-lead diameters must select alternative drill sizes from the range. The tool shank fits standard precision collets used in PCB drilling machines, but compatibility with a specific spindle should be verified before purchase.

Questions about this item

Does the No 84 Twister GP drill produce noticeable heat or noise during extended circuit-board work?

The drill is designed for precision circuit-board drilling; typical operation generates minimal heat and low noise suitable for bench use.

What power-tool chuck or collet must I already have to fit the 30201150 shank?

The drill uses a standard shank compatible with common 1/8-inch collets and pin vises used for PCB drilling.

Will the No 84 Twister GP drill work reliably in an older manual drill press I already own?

Yes, the drill fits the standard chuck of most benchtop drill presses and runs true at the low speeds those machines provide.
