M.A. Ford Twister GP No 100 Circuit Board Drill

The M.A. Ford Twister GP No 100 is a precision drill designed for circuit board work. It suits technicians and engineers who need accurate hole placement in composite materials. The tool is supplied new and carries the manufacturer part number 30200470. It is built for controlled drilling in professional electronic assembly and repair environments.

Replaces worn or undersized drills for tighter

Upgrading to this drill is worthwhile when existing bits produce rough hole walls or wander on dense laminate. The Twister GP geometry improves centring and chip evacuation in abrasive glass-epoxy boards. The jump makes sense for shops seeing increased scrap rates or rework on high-density layouts. It addresses the need for cleaner holes without changing machine set-ups.

Handles fine-pitch drilling in standard FR-4

The No 100 diameter provides headroom for typical via and component lead sizes found in general-purpose boards. It runs out when hole diameters drop below this size or when material thickness exceeds the flute length. Very high-volume production may demand carbide grades with specialised coatings not featured here. Buyers needing smaller diameters or extended reach should look elsewhere.

Questions about this item

What size chuck or collet does the No 100 drill require?

The No 100 drill is a standard circuit-board bit; it fits the chuck or collet size specified for your drill press or hand-piece.

How do I install the 30200470 bit without snapping the carbide tip?

Insert the shank fully, tighten the chuck evenly, and start the spindle before contacting the board — plunging a stationary bit is the common mistake.

When should I replace the Twister GP drill?

Replace it when the cutting edges dull, the tip chips, or hole quality degrades; carbide circuit-board drills cannot be economically resharpened.
