Cleveland C04649 53/64" HSS Bright 118 Deg Jobber Drill Bit

Cleveland C04649 Jobber Drill Bit

The Cleveland C04649 is a fractional-inch jobber-length drill bit made from high-speed steel with a bright uncoated finish. It is designed for general-purpose drilling in metal, wood and plastic where a standard 118-degree point angle is suitable. The straight shank fits common three-jaw chucks on handheld drills and drill presses. It serves trade professionals and workshop users who need a single replaceable bit in this specific size.

53/64 inch capacity and material limits

The bit drills a 53/64 inch hole, which is 0.8281 inch in decimal terms. High-speed steel construction gives adequate wear resistance for mild steel, aluminium and non-ferrous alloys at appropriate speeds. The uncoated bright finish offers no additional heat or friction barrier, so tool life drops quickly in stainless steel, hardened materials or high-volume production runs. Deep holes beyond the flute length will require frequent pecking to clear chips.

Thermals noise and power draw in normal use

A single HSS drill bit generates heat only at the cutting interface; the workpiece and spindle absorb the bulk of thermal energy. Noise comes from the driving machine and chip evacuation, not from the bit itself. Power demand depends entirely on the drill motor, feed pressure and workpiece hardness, so no standalone figure applies to the accessory. Proper cutting fluid and speed selection keep temperatures manageable for the tool and the machine.
