29-piece jobber drill bit set

The Cle-Line C21159 contains 29 high-speed steel jobber drill bits finished in black oxide. It is aimed at technicians and maintenance crews who need a broad range of fractional sizes in one organised package.

118-degree point angle for steady cutting

The 118-degree point angle is designed for general-purpose drilling in steel and other ferrous metals. Under sustained load the geometry helps maintain centring and reduces wandering compared with sharper profiles, giving consistent material removal across repeated holes.

Black oxide finish aids heat dissipation

The black oxide coating improves lubricity and helps dissipate heat during normal use, lowering the tendency for workpiece material to weld to the cutting edges. This extends edge life and keeps cutting forces predictable without requiring excessive feed pressure.

Questions about this item

How much heat does the high-speed steel generate when drilling all day?

High-speed steel with a black oxide finish resists heat buildup during extended drilling sessions. The 118-degree point angle helps dissipate heat efficiently across the cutting edges.

What drill chuck size is required for the reduced shank design?

The reduced shank fits a standard 3/8-inch chuck, so any drill with that capacity will accept all 29 bits without needing an adapter or larger chuck.

Will these bits work in an older corded drill with a keyed chuck?

Yes, the reduced shank design fits any 3/8-inch keyed or keyless chuck, making the set compatible with older corded drills as well as modern cordless models.
