9.50 mm Twister Brad & Spur Drill

The M.A. Ford 20737400 is a 9.50 mm Twister Brad & Spur Drill designed for precise drilling in wood and similar materials. It suits professional tradespeople and serious DIY users who need clean entry holes and accurate hole placement. The brad point centres the bit without wandering. The spur cutting edges shear wood fibres for a smooth bore.

Thermals noise and power draw

Heat generation depends on the drill motor speed, feed pressure and workpiece density rather than the accessory itself. The high-speed steel construction resists tempering loss during repeated holes. No electrical or pneumatic power is consumed by the bit alone. Vibration and noise levels are determined by the driving tool and the material being drilled.

Build quality and shank fit

The bit is manufactured from high-speed steel for edge retention and durability in abrasive wood species. Its round shank fits standard three-jaw chucks and quick-change holders without adapters. The California Proposition 65 notice indicates the presence of listed chemicals; users should follow normal workshop hygiene such as washing hands after handling. The 20737400 part number allows exact reorder matching.

Questions about this item

How do I install the 9.50 mm Twister Brad & Spur Drill in my drill press, and what step is often missed?

Chuck the shank fully and tighten securely; the step often missed is verifying the bit runs true before starting the cut.

What maintenance or replacement will the 20737400 drill need over time?

The cutting edges will dull with use; plan to resharpen or replace the bit when hole quality degrades.

What limit appears first when drilling deep holes with this 9.50 mm bit?

Chip evacuation becomes the bottleneck — deep holes pack the flutes, causing heat and wander; withdraw frequently to clear swarf.
