A 3.70 mm Brad and Spur drill bit cuts clean flat-bottom holes in wood

  • Precision drilling with 3.70 mm Twister Brad & Spur bit
  • Clean entry holes reduce splintering in wood and composites
  • M.A. Ford industrial-grade construction for lasting sharpness
  • California Prop 65 warning for cancer and reproductive harm
  • Manufacturer direct shipping on orders over 75

Application

The M.A. Ford Twister Brad & Spur Drill creates clean entry holes in wood and similar materials. Its 3.70 mm diameter suits fine joinery and pilot-hole tasks for woodworkers and installers.

Standard limits

The brad point centres the bit without wandering, while the spur cuts the perimeter for a smooth bore. Performance drops in hard plastics or metals because the geometry is optimised for timber only.

Compatibility check

Verify that your drill chuck accepts a 3.70 mm shank and that the workpiece thickness matches the flute length. The product carries a California Proposition 65 warning for substances linked to cancer and reproductive harm.

Questions about this item

Should I choose the 3.70 mm Twister Brad & Spur Drill 20714570 for my project?

Select the 3.70 mm 20714570 when you need a precise 3.70 mm hole with clean entry and minimal tear-out in wood or composite materials.

How does the 3.70 mm diameter perform in a real drill press or hand drill?

The 3.70 mm brad point centres accurately and the spur cutting edges shear wood fibres for a clean hole at that exact size.

What shank interface does the 20714570 use and what does it limit?

The 20714570 uses a standard round shank that fits common three-jaw chucks, limiting use to drills that accept that shank diameter.
