4.90 mm Brad Spur Drill

This M.A. Ford Twister drill bit is designed for precise brad and spur drilling tasks in workshop and automotive settings. The 4.90 mm diameter suits applications requiring that exact hole size. It is supplied new and ships directly from the manufacturer.

Replaces worn or undersized bits

When an existing bit no longer cuts cleanly or cannot achieve the required 4.90 mm diameter, this Twister drill provides a direct replacement. The upgrade is worth it when accuracy and hole quality are critical for the fastener or joint being prepared.

Handles 4.90 mm holes in compatible materials

The bit comfortably produces 4.90 mm diameter holes in materials suited to brad and spur geometry. It runs out when the workpiece demands a different diameter, deeper reach than the flute allows, or a material hardness outside the design envelope.

Questions about this item

Will the 4.90 mm drill shank fit a standard three-jaw chuck?

The 4.90 mm diameter shank is designed to be held securely by any standard drill chuck that accepts bits up to at least 4.90 mm.

What is the correct way to start a hole with this Twister Brad Spur drill?

Apply light pressure and let the brad point centre the bit before the cutting spurs engage; forcing the drill before the point seats is the step most often done wrong.

How will I know when this 20719290 bit needs replacing?

Replace the bit when the brad point or outer spurs become dull, chipped, or when the drill starts to wander or burn the wood instead of cutting cleanly.
