  • 70 mm diameter suits micro-machining tasks
  • California Proposition 65 warning informs safe handling

Twister Coolant 10X Micro Drill 2.70mm

The M.A. Ford Twister Coolant 10X Micro Drill is a precision cutting tool with a 2.70mm diameter designed for high-performance drilling applications. It features internal coolant delivery for effective heat management and chip evacuation during deep-hole operations. The 10X length-to-diameter ratio enables extended reach in a single pass. This accessory targets machinists and manufacturers requiring accurate small-diameter holes in metals and alloys.

Installation and common issues

The micro drill installs into compatible high-speed spindles or CNC tool holders using standard collet or chuck systems matched to its shank dimensions. Proper coolant pressure and filtration are essential to prevent blockage of the internal channels. Common issues include premature wear from insufficient coolant flow, vibration caused by excessive runout, and breakage if feed rates are not optimised for the specific workpiece material. Careful toolholder maintenance minimises runout-related failures.

Suitability and alternatives

This drill suits production environments needing reliable deep-hole capability in diameters around 2.70mm with through-coolant spindles. It is not intended for handheld use or machines lacking coolant-through capability. Buyers requiring larger diameters, different length ratios, or non-coolant-through tooling should consider other options. The Proposition 65 notice indicates the presence of listed chemicals, which may affect material handling procedures in regulated workplaces.

Questions about this item

How do I confirm the 10X coolant-fed drill is cutting correctly at 2.70 mm?

Check for consistent chip evacuation through the coolant holes, steady spindle load, and a clean 2.70 mm hole diameter with no discolouration on the workpiece.

What comes in the package and what must I supply separately?

The box contains the 2MDCL1063A Twister Coolant 10X Micro Drill only; you must provide a compatible coolant-through tool holder, high-pressure coolant system, and appropriate work-holding.

Which variant should I choose for a 2.70 mm hole depth requirement?

Select the 10X diameter-to-length version when your hole depth is up to ten times the 2.70 mm diameter; shorter depths can use lower-ratio drills instead.
