23/64" Jobber Drill Bit for General Drilling
This 23/64" jobber length drill bit is made from high speed steel for general purpose drilling in metal, wood and plastic. The 118 degree conventional point provides reliable centring and chip ejection across a range of materials. It suits trade professionals and DIY users who need a fractional inch bit for everyday workshop tasks.
Bright Finish Affects Lubrication and Wear
The bright uncoated surface means no coating layer to wear away, but it also offers less built-in lubricity than black oxide or gold oxide finishes. Users must supply cutting fluid or oil when drilling steel to prevent overheating and extend bit life. The lack of coolant holes requires frequent withdrawal to clear swarf in deeper holes.
Straight Shank Fits Standard Chucks
The straight shank installs directly into any 3-jaw drill chuck that accepts 23/64" capacity, with no adapter needed. The main installation risk is insufficient chuck tightening, which allows the bit to spin or slip under load. The conventional point can walk on hard or angled surfaces unless a centre punch mark is used first.

Questions about this item
Will the 23/64 inch high speed steel tip need resharpening after repeated drilling?
Yes, the conventional 118 degree point on this high speed steel bit will dull with use and can be resharpened to restore cutting performance.
What stops the 23/64 inch bit from going deeper during a long drilling cycle?
The jobber length flute and shank determine the maximum drilling depth, and the lack of coolant holes means heat buildup will limit continuous run time.
How hot does the 44423 bit get when drilling steel all day?
Without coolant-through channels the bright high speed steel body relies on external lubrication, so sustained high-speed drilling will generate significant heat at the 118 degree point.
