A 5.20 mm Twister Brad and Spur Drill for clean, accurate holes in wood
- Twister design for clean entry holes in wood
- Brad point centres the bit without wandering
- Spur cutting edges shear fibres for smooth sides
- 20 mm diameter matches precise pilot-hole requirements
- M.A. Ford manufacturing ensures consistent hardening and flute geometry
Purpose and user
The M.A. Ford Twister Brad and Spur Drill 5.20 mm 20720470 is a power tool accessory designed for drilling clean, accurate holes in wood. It suits woodworkers and joiners who need a bit that reduces splintering on entry and exit.
Build integration
The 5.20 mm diameter fits standard drill chucks and works with corded or cordless drills. Its brad point centres the cut without a pilot hole, freeing the user from extra layout steps.
Thermals, noise and power
Heat and noise depend on the drill motor and workpiece density rather than the bit itself. The accessory draws no power of its own and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item
How deep can the 5.20 mm Twister Brad and Spur Drill bore before chip clearance becomes the limiting factor?
The 5.20 mm diameter and brad-point geometry determine chip evacuation; deep holes in dense wood require frequent withdrawal to prevent packing and overheating.
What heat or noise level should be expected when the 20720470 drill runs continuously in a drill press all day?
The high-speed steel cutting edges generate heat proportional to feed rate and material density; use cutting fluid and allow cooling intervals to manage temperature.
What shank size must my drill chuck accept for the 20720470 bit to fit securely?
The bit uses a standard round shank sized for the 5.20 mm body; a three-jaw chuck that closes fully to 5.20 mm or a collet of that diameter is required.
