SKU CH-8GBS-MMY8Q

Coolant-fed drill delivers 7x diameter depth at 6.90mm for efficient machining

  • 90 mm diameter drills precise holes in one pass
  • 7X+ flute geometry clears chips faster for deeper cuts
  • Coolant-fed design reduces heat and extends tool life
  • Twister XD construction handles high-speed drilling in tough alloys
  • California Prop 65 warning informs safe handling practices

M.A. Ford Twister XD 7X+ Coolant Fed Drill 6.90mm

This professional-grade drill bit is manufactured by M.A. Ford for precision hole-making in industrial and automotive applications. The 6.90mm diameter suits metalworking tasks requiring accurate sizing. It is built for high-performance drilling in demanding workshop environments.

Coolant-fed design for chip evacuation

Internal coolant channels deliver fluid directly to the cutting zone to flush chips and manage heat during deep-hole drilling. This feature supports consistent tool life and hole quality in tough materials. The 7X+ geometry enhances stability and cutting efficiency.

Suited for CNC and high-volume production

Machinists running coolant-through spindles on CNC centres will benefit from the through-tool delivery. Operators limited to external flood coolant or hand-held drilling cannot use the internal feed capability. Buyers needing different diameters or non-coolant-fed styles should select alternative tooling.

Questions about this item

When will the 6.90 mm cutting edges need resharpening?

Resharpen when flank wear reaches the manufacturer’s recommended limit; the 6.90 mm diameter can typically be reground several times before replacement.

What limits continuous drilling with the 2717 series coolant-fed design?

Chip evacuation and coolant pressure become the practical limits; maintain clean filters and correct flow to sustain performance.

How much heat and noise does the Twister XD generate during all-day operation?

Expect typical industrial drilling noise and heat; the internal coolant channel reduces cutting-zone temperature and helps manage thermal buildup.
