SKU CH-TD4A-0W2E7

A 7.80 mm solid carbide drill for high-performance drilling applications

  • 3X flute design clears chips efficiently in deep holes
  • Solid carbide construction maintains edge hardness under high heat
  • 80 mm diameter matches precise drilling requirements
  • Twister Xd geometry reduces thrust force for smoother cuts
  • M.A. Ford manufacturing delivers consistent hole quality

Solid carbide drill for metalwork

The M.A. Ford Twister Xd 3X is a solid carbide drill bit with a 7.80 mm cutting diameter. It is designed for machinists and maintenance technicians who need accurate holes in steel, stainless steel or cast iron. The 3X geometry supports higher feed rates and longer tool life in production environments. Buyers who require coolant-through capability or a larger diameter range should look elsewhere.

Prop 65 notice affects handling only

The product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm. This notice does not change the drill’s cutting performance or material composition. It simply requires the user to follow standard workshop hygiene such as washing hands after use and avoiding dust inhalation. No additional accessories or software are bundled with the bit.

Standard shank fits common holders

The drill uses a straight shank that fits standard collets, drill chucks and tool holders without adapters. Installation is a matter of clamping the shank securely and checking run-out before cutting. The most common issue is premature wear caused by incorrect speed or feed settings for the workpiece material. Using the manufacturer’s recommended parameters avoids this problem.

Questions about this item

When should the 7.80 mm solid carbide drill be resharpened or replaced?

Resharpen when flank wear or edge chipping reduces hole quality; solid carbide permits multiple regrinds before the shank reaches minimum length.

What limits continuous drilling with the Twister Xd 3X?

Heat buildup in the workpiece and chip evacuation capacity are the first constraints during sustained use.

How much heat and noise does the 7.80 mm drill generate in all-day operation?

Expect typical high-speed drilling noise and localized heat at the cutting zone; use coolant to manage temperature.
