Micro-Tuff Drill 1.55 mm

The M.A. Ford Twister Micro-Tuff Drill 1.55 mm is a precision cutting tool designed for drilling small-diameter holes in a range of materials. It suits machinists and technicians who need a reliable micro-drill for detailed workshop tasks.

Micro-Tuff coating advantage

The Micro-Tuff coating increases surface hardness and reduces friction during cutting, which helps the drill maintain its edge longer than an uncoated equivalent. This extends tool life and supports consistent hole quality across repeated use.

1.55 mm diameter capacity

At 1.55 mm the drill handles fine-hole applications such as pilot holes, instrumentation work and small fastener clearance. It is not intended for larger diameters or heavy stock removal where a standard twist drill would be more appropriate.

Questions about this item

When will the 1.55 mm Twister Micro-Tuff drill bit need replacing?

Replace the bit when the cutting edges no longer produce clean holes or when feed pressure must be increased noticeably; no fixed interval is defined for this diameter.

What limits continuous drilling with the 305M0155 bit first?

Heat buildup in the 1.55 mm cutting zone typically becomes the limiting factor before the shank or flute geometry restricts performance.

How hot does the 1.55 mm drill get during all-day use?

The bit will become hot to the touch during prolonged drilling; allow cooling periods and use appropriate cutting fluid to manage temperature.
