Cle-Line C22507 27/64 in 118° Jobber Drill Bit

27/64 in Jobber Drill Bit

The Cle-Line C22507 is a fractional-inch jobber length drill bit sized at 27/64 in. It is made from high-speed steel with a black oxide finish. The conventional 118-degree point suits general-purpose drilling in metal, wood and plastic. This bit is aimed at mechanics, fabricators and maintenance technicians who need a standard-length tool for everyday hole-making.

118° Point and Straight Shank

The 118-degree conventional point centres quickly without a pilot hole and works in standard drill chucks. A straight shank fits three-jaw chucks on bench presses, hand drills and magnetic base drills. No coolant holes are present, so the bit relies on external lubrication or peck drilling for deeper holes. The jobber length provides typical reach for through-holes and blind holes in sheet metal, plate and structural sections.

0.4219 in Decimal Size

The 27/64 in diameter equals 0.4219 in decimal form, giving a precise reference for tap-drill charts and fixture layouts. High-speed steel with black oxide resists wear in mild steel, aluminium and non-ferrous alloys. The bit is not suited for hardened steels, high-temperature alloys or production-volume drilling where cobalt or carbide tooling would last longer. It also lacks through-coolant capability for deep-hole applications.
