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.

Questions about this item
What is the 118° point angle designed for?
The standard 118° conventional point tip is designed to perform in a broad range of materials in the iron and steel families, including stainless steel, cast iron, and angle iron.
What chuck size is required for the 1 in. straight shank?
The bit features a 1 in. diameter straight shank with a 5 in. shank length, requiring a chuck capacity of at least 1 in. Round shanks allow use with a wide variety of tool holding systems.
How do you prevent the 18 in. bit from walking on hard steel?
Use a centre punch to mark the hole centre, apply cutting fluid, and start drilling at low RPM with firm pressure; the 118° point and 13 in. flute length help clear chips in deep holes.
