M.A. Ford 30613600 Twister Large Size Circuit Board Drill No 29 pneumatic accessory

M.A. Ford Twister Drill No 29

The M.A. Ford 30613600 Twister is a large-size circuit board drill designated No 29. It is built for precision drilling in composite board materials during electronics fabrication or repair work. The accessory fits pneumatic power systems used in professional workshops. Buyers who need smaller diameters or non-pneumatic shank styles will not be served by this specific tool.

Pneumatic fit for board drilling

This drill requires a compatible pneumatic driver or rotary tool with the correct collet or chuck capacity for its shank. It replaces hand-fed drilling where repeatability and speed matter in production environments. The design frees the operator from manual feed pressure, letting the air motor maintain consistent material removal. Workshops without a regulated compressed-air supply cannot use this accessory.

Sustained cutting in composite boards

Under continuous operation the cutting geometry evacuates fibreglass dust and resin residue to reduce binding in deep holes. The carbide construction resists the abrasive wear typical of FR-4 and similar laminates over long runs. Heat builds more slowly than with high-speed steel, so hole wall quality remains stable across multiple panels.
