Solid carbide jobber drill bit #20

The Drill America DMOD20 is a solid carbide jobber-length drill bit sized #20 with an overall length of 2.5 inches. It features a round shank, spiral flutes, and a 118-degree conventional point. The uncoated bright finish is intended for general-purpose drilling in abrasive or high-temperature applications.

Machinists drilling cast iron or non-ferrous alloys

This bit suits machinists who need to maintain accuracy in cast iron, non-ferrous alloys, high-silicon aluminium, copper, plastics, bronze, hard rubber, or plexiglass. It is not for buyers who require a coated tool for extended wear resistance in ferrous steels, nor for those needing a larger diameter or different point geometry.

Sustained high-temperature drilling performance

Solid carbide construction retains hardness at elevated temperatures, allowing the bit to hold size and finish during prolonged cuts in abrasive materials. The 118-degree point centres without a pilot hole, while the spiral flutes clear chips efficiently. The uncoated surface avoids coating delamination under thermal cycling.

Questions about this item

Does my drill chuck accept the round shank on this #20 carbide bit?

Yes — the bit has a round shank that fits any standard three-jaw chuck sized for a #20 drill.

Will the 118° point still cut cleanly in cast iron if I keep using my older steel bits for other jobs?

The 118° conventional point is designed for abrasive materials such as cast iron and holds accuracy even when mixed with general-purpose steel bits.

How can I confirm the bit is performing correctly after the first hole?

Check that the hole diameter matches the #20 size and that the walls show no chatter or oversize from the 1-3/8" flute length.
