M.A. Ford Twister Xd 3X Drill 9.90 mm

The M.A. Ford Twister Xd 3X is a solid carbide drill bit sized at 9.90 mm. It is built for machine shops and maintenance teams that need precise hole-making in tough materials. The carbide construction resists wear and holds centre without a pilot hole. This accessory fits standard drill holders and CNC tooling.

Suited to high-volume metal cutting.

Machinists drilling steel, stainless alloys or cast iron will benefit from the rigid carbide body and 3X geometry. The tool is not designed for soft non-metallics, hand-held drilling in unsecured workpieces, or applications that require coolant-through capability. Buyers needing larger diameters or different flute lengths must select another variant.

9.90 mm cutting diameter

The 9.90 mm diameter is the critical dimension that determines fit for the intended hole size. Verify the required tolerance and hole specification before ordering. No other diameter options are included in this listing.

Questions about this item

How do I install the 9.90 mm Twister Xd drill in my drill chuck, and what step is often missed?

Open the chuck jaws wide enough for the 9.90 mm shank, insert the drill fully so the shank seats against the chuck face, then tighten securely. The step often missed is verifying the drill runs true with a dial indicator before cutting.

What maintenance or replacement will the solid carbide 9.90 mm drill need over time?

The solid carbide body cannot be resharpened economically. Replace the drill when the cutting edges show visible wear, chipping, or when hole diameter exceeds tolerance. No other maintenance is required.

What limit appears first on the 3X solid carbide drill during sustained high-speed drilling?

Heat buildup at the cutting edges is the first limit. Without adequate coolant flow, the carbide can overheat, leading to premature edge wear or catastrophic fracture of the 9.90 mm tool.
