M.A. Ford 6.90 mm coolant drill
The M.A. Ford HPDCR 0690A Twister HPD is a 6.90 mm high-performance coolant drill built for precision drilling in metalworking environments. It suits machinists and maintenance teams who need accurate hole-making with integrated coolant delivery. The 5X design supports deeper drilling cycles without frequent tool changes. This new item ships directly from the manufacturer.
Straightforward installation with coolant setup
The drill fits standard tool holders that accept a 6.90 mm shank, so mounting is quick on compatible CNC machines or drill presses. The main difficulty lies in aligning the through-coolant channels correctly; misalignment can starve the cutting zone of fluid and cause premature wear. Operators must verify that the machine’s coolant pressure matches the tool’s internal passages. No special adapters are mentioned in the supplied data.
Practical limits of the coolant-fed interface
The through-coolant design improves chip evacuation and tool life, but it depends on a consistent, filtered coolant supply at adequate pressure. If the machine’s filtration is poor, particles can block the internal passages and stop coolant flow. The 5X length-to-diameter ratio allows deeper holes, yet deflection risk rises in harder alloys without rigid workholding. California Proposition 65 warnings note chemicals linked to cancer and reproductive harm.

Questions about this item
How do I confirm the 6.90 mm drill is cutting correctly after setup?
Check that the coolant flows steadily through the tool and that the hole diameter matches 6.90 mm with clean chip evacuation.
What comes in the box with the HPDCR 0690A and what must I supply?
The drill itself is included; you must provide a compatible coolant system and a holder suited to 6.90 mm shank tools.
Which capacity of the Twister HPD Coolant Drill should I choose for a 6.90 mm hole?
Select the 6.90 mm variant — it is the only size that produces a 6.90 mm hole.
