6.40 mm coolant-fed drill
The M.A. Ford Twister Xd is a 6.40 mm solid-carbide drill supplied with internal coolant channels. It is intended for machinists and maintenance teams who need reliable hole production in steels and cast irons on CNC machines or rigid manual drills. The 3× diameter flute length suits standard through-hole depths without pecking.
Coolant pressure and chip evacuation
Internal coolant delivery only works when the machine spindle and tool holder supply sufficient pressure to clear chips from the full 3× depth. Low-pressure systems or flood coolant alone may leave chips in the hole, causing premature wear or breakage. The drill cannot compensate for inadequate coolant volume or poor filtration.
Shank fit and holder rigidity
The cylindrical shank demands a high-precision collet or hydraulic holder to maintain run-out within microns; worn ER collets or side-lock holders will degrade hole quality and tool life. No flats or whistle-notch features are present, so torque transmission relies entirely on clamping force. California Proposition 65 warnings apply to the coating composition.

Questions about this item
Which Twister Xd 3X coolant-fed drill size should I pick for a 6.40 mm hole?
The 2XDCS2520A is ground to 6.40 mm, so choose this variant when the finished hole must be exactly that diameter.
What does the 3X designation mean once the drill is in the machine?
It indicates a 3 × diameter flute length, giving deeper chip clearance and longer reach in a single pass compared with shorter series.
How does the coolant-fed shank affect performance on a standard CNC spindle?
Internal coolant exits at the tip, improving chip evacuation and tool life in deep holes, provided the spindle and holder supply coolant through the centre.
