7.40 mm coolant drill application
The M.A. Ford Twister HPDCR 0740A is a high-performance coolant drill built for precision hole-making in demanding materials. Its 7.40 mm diameter suits production drilling where consistent chip evacuation and tool life matter. Machinists and fabricators running CNC or rigid manual setups will find it suited to repeatable throughput.
5× diameter depth capacity
The 5× length-to-diameter ratio provides reach for holes up to roughly five times the drill diameter before pecking becomes necessary. Through-coolant delivery extends practical depth by flushing chips and controlling heat at the cutting zone. In deep or abrasive cuts the flute length eventually limits chip clearance, requiring intermittent withdrawal.
Through-coolant changes chip control
Internal coolant passages direct fluid to the cutting edges, reducing built-up edge and improving surface finish in stainless steels and high-temp alloys. The design eliminates the need for external flood lines that can miss the hole entry. Shops without through-spindle coolant capability cannot use this feature and would need a solid-shank alternative.

Questions about this item
Will the 7.40 mm Twister HPD coolant drill work in the same tool holder as my existing 7.40 mm drills?
Yes, the 7.40 mm diameter matches standard holders for that size, so it fits without an adapter.
How can I confirm the 5X coolant drill is delivering coolant correctly after installation?
Run the machine at low speed and observe steady coolant flow from the drill’s internal channels at the cutting point.
Does the box include only the 7.40 mm Twister HPD drill or are collets and coolant fittings also supplied?
The package contains the 7.40 mm drill only; collets, holders and coolant fittings must be purchased separately.
