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.

Questions about this item
Will the 118° point angle hold up in a production run without walking?
The 118° conventional point is ground for general-purpose drilling and resists walking on flat surfaces when the feed is steady and the workpiece is clamped.
Does the black-oxide finish stay cool enough for continuous drilling in mild steel?
Black oxide reduces friction and helps dissipate heat, but the bit has no coolant holes so you must apply cutting fluid and clear chips frequently during long sessions.
What shank size does the 27/64 in bit need in my drill chuck?
The bit is a straight-shank jobber length with a 27/64 in (0.4219 in) shank, so your chuck must open at least that wide.
