Questions about this item

Does the Twister Micro-Tuff Drill No 90 generate noticeable heat or vibration during extended drilling cycles?

The drill is a solid-carbide micro-tool designed for high-speed precision work; heat build-up depends on spindle speed, feed rate, coolant use and the workpiece material rather than on the drill itself.

What shank diameter and holder type does the No 90 drill require to mount in my machine?

The drill carries the manufacturer part number 30500870; the exact shank diameter and holder interface are detailed in the M.A. Ford technical catalogue for this item.

Will the No 90 drill fit in the same tool changer pockets or collets I already use for older micro-drills?

Compatibility with existing pockets or collets is determined by the drill's shank specification, which is listed in the M.A. Ford data sheet for part 30500870.
