Drill America 1 in. x 18 in. High Speed Steel Extra Long Drill Bit Straight Shank

1-Inch x 18-Inch Extra Long Drill Bit

This high-speed steel twist bit measures 18 inches overall with a 13-inch flute length and a 5-inch straight shank. The 118-degree conventional point handles a broad range of materials including wood, iron, steel, stainless steel, aluminum, copper, cast iron, PVC, plaster, vinyl flooring, nickel, angle iron, duct metal and sheet metal. The round shank fits a wide variety of tool holding systems. It is sold individually as a general-purpose accessory for reach-intensive drilling.

Ideal for deep-reach drilling in mixed materials

The extra length suits tradespeople and DIY users who must drill through thick workpieces, deep cavities or hard-to-access locations across the listed metals, woods and plastics. Builders who need a self-feeding screw point, a reduced shank for smaller chucks, or a cobalt or carbide tip for hardened alloys should look at other designs. The single-piece pack also means buyers needing multiple diameters must purchase each size separately.

1-Inch diameter straight shank requires full-size

The bit’s shank and cutting diameter are both 1 inch, so the drill or press must accept a 1-inch straight shank; smaller chucks cannot hold this bit. No other specification overrides this mechanical requirement.
