8.20 mm coolant drill for high-performance drilling
The M.A. Ford HPDCR 0820A Twister HPD drill is a solid-carbide tool with a 5× diameter flute length and through-coolant holes. It is designed for machine shops that need deep, accurate holes in steel, stainless steel and high-temperature alloys.
Coolant pressure and machine rigidity limit
Through-coolant delivery evacuates chips from the 5× depth, but the maximum usable depth still depends on the machine spindle run-out, holder grip force and available coolant pressure. Excessive run-out or low coolant flow will cause chip packing and premature wear at the full 5× reach.
Standard shank fits common holders.
The cylindrical shank installs in hydraulic, shrink-fit or precision collet holders without adapters. The most common issues are excessive holder run-out that breaks the carbide at the margin and insufficient coolant sealing that starves the flutes during deep cuts.

Questions about this item
Should I pick the 8.20 mm Twister HPD coolant drill or a different diameter for my job?
Choose the 8.20 mm size when the hole must be exactly that diameter; other diameters are separate part numbers.
What does the 5X designation mean once the drill is in the machine?
It indicates a 5-times-diameter flute length so the 8.20 mm drill can reach deeper in a single pass.
Does the coolant-fed shank follow a specific industry standard that limits pressure or flow?
The shank accepts standard through-coolant holders; pressure and flow limits depend on the holder and machine, not the drill itself.
