10.50 mm Brad and Spur Drill

The M.A. Ford Twister drill bit measures 10.50 mm and carries part number 20741340. It is a new accessory designed for power and pneumatic tools in automotive and general workshop tasks. The brad and spur geometry helps start holes cleanly in wood and similar materials.

Thermals noise and power

As a non-powered cutting accessory the drill produces no electrical noise or heat of its own. Thermal load and sound levels depend entirely on the drill motor and workpiece being used. Power draw is determined by the host tool rather than the bit itself.

Proposition 65 notice included

The packaging carries a California Proposition 65 warning that the product contains a chemical known to cause cancer and a chemical known to cause birth defects or other reproductive harm. No additional software or accessories are bundled with the drill bit.

Questions about this item

How do I install the 10.50mm Twister Brad and Spur Drill 20741340 in my drill chuck?

Open the chuck fully, insert the shank completely, and tighten evenly on all three jaws. The step people miss is checking that the bit runs true before drilling.

What maintenance will the 20741340 Twister Brad and Spur Drill need after extended use?

Clean wood resin from the flutes and spur after each job. Sharpen the brad point and cutting lips when they dull, and wipe the surface lightly with oil to prevent rust.

What limit appears first when using the 10.50mm M.A. Ford Twister drill continuously in hardwood?

Heat buildup at the cutting edges dulls the brad point and spurs first, causing wandering and tear-out. Clear chips frequently and reduce feed pressure to delay this.
