M.A. Ford Twister XD 7X+ Coolant Fed Drill 10.10mm

Twister XD 7X+ coolant-fed drill 10.10 mm

The M.A. Ford Twister XD 7X+ is a coolant-fed drill bit sized at 10.10 mm for precision hole-making in metal. It targets machinists and maintenance teams who need consistent chip evacuation and tool life in production drilling. The through-coolant design delivers fluid directly to the cutting zone. This reduces heat buildup and improves hole quality in deep or difficult materials.

Capacity and headroom at 10.10 mm

The 10.10 mm diameter handles standard metric fastener clearance and dowel holes in steel, stainless steel and cast iron. Coolant feed extends practical drilling depth beyond what solid drills achieve without pecking. The limit is reached when hole depth exceeds the flute length or when machine coolant pressure cannot sustain flow at the tip. Very large batch sizes may still demand indexable tooling for lowest cost per hole.

Upgrade from solid non-coolant drills

This bit replaces conventional solid carbide or HSS drills that rely on external flood coolant. The jump is worth it when drilling deeper than three diameters, when cutting difficult alloys that work-harden, or when cycle time must drop through higher feed rates. Shops without through-spindle coolant capability cannot use the internal channel. Buyers needing diameters outside 10.10 mm must select a different size.
