M.A. Ford Twister Xd 7X+ Coolant Fed Drill 6.40Mm

6.40 mm coolant-fed drill bit

The M.A. Ford Twister Xd 7X+ is a solid-carbide drill designed for high-performance hole-making in demanding materials. Internal coolant channels deliver lubricant directly to the cutting zone, improving chip evacuation and tool life. It targets machine shops and production environments that require consistent accuracy at elevated speeds.

Sustained-load behaviour with internal coolant

Coolant fed through the tool body stabilises cutting temperatures during extended drilling cycles, reducing thermal shock to the carbide substrate. The 7X+ geometry maintains chip control at high penetration rates, preventing packing that can catastrophically fail the drill in deep holes. Continuous operation benefits from the consistent heat removal that external flood coolant cannot match.

Replaces external-coolant or non-coolant drills

Shops moving from conventional twist drills or external-coolant carbide tools gain deeper-hole capability and longer intervals between regrinds. The upgrade is justified when hole depth exceeds five diameters or when difficult alloys cause premature wear on standard tools. Operations limited to shallow holes in free-machining materials will not realise the full return on investment.
