M.A. Ford 30614950 Twister Circuit Board Drill No 25

M.A. Ford Twister Circuit Board Drill No 25

This M.A. Ford Twister drill is a large-size circuit-board accessory designed for precision hole-making in composite substrates. It targets technicians and engineers who need clean, accurate entries in printed-circuit material during prototype or production runs. The tool fits standard high-speed spindles used in dedicated PCB drilling stations.

Drill size No 25 capacity and headroom

The No 25 diameter handles the via and component-hole sizes most common in medium-density board layouts. It maintains concentricity through the full stack height of typical multilayer panels. The geometry runs out when hole counts push cycle times beyond the spindle’s thermal limits or when hole diameters fall below the next standard size down.

Upgrade from standard HSS drills

This Twister design replaces general-purpose high-speed steel drills that wander or fray glass-epoxy layers. The step up is justified when hole-wall quality directly affects plating yield or when drill-change frequency becomes a bottleneck. Buyers who need smaller micro-via diameters or exotic substrate materials will need a different tool specification.
