Circuit Board Drill 3/16

The M.A. Ford Twister is a large-size drill bit designed for circuit board fabrication. It targets technicians and engineers who need precise holes in composite materials. The 3/16 inch diameter suits specific via and through-hole requirements.

Practical Drilling Limits

Performance depends on the rigidity of the drilling machine and the workpiece clamping. Feed rates and spindle speeds must match the substrate to avoid breakage or delamination. The tool is not suited for hand-held use or high-volume production without proper equipment.

Installation and Common Issues

The drill fits standard collets or chucks accepting the 3/16 shank. Secure clamping is essential to prevent runout and premature wear. Common failures include tip chipping from excessive feed pressure and shank slippage in worn holders.
