Cle-Line #7 Jobber Drill Bit
This Cle-Line C23207 drill bit is a high-speed steel jobber length tool designed for general-purpose drilling tasks. Its 135-degree split point allows for accurate starts without a centre punch. The black oxide finish helps resist wear and corrosion during use. It suits workshops and maintenance crews needing reliable hole-making in metal.
135-degree split point capacity
The 135-degree point angle and split-point geometry reduce walking and lower thrust requirements when drilling into steel and other alloys. Decimal size 0.2010 inches fits standard #7 clearance and tapping charts. The jobber length provides standard reach for through-holes and moderate-depth work. It is not suited for deep-hole or coolant-fed operations.
High-speed steel practical limits
High-speed steel construction performs well in portable drilling and light machine work at recommended speeds. Without internal coolant holes, chip evacuation relies on peck cycles in deeper cuts. The black oxide surface holds lubricant but does not replace flood coolant in high-heat applications. Users needing through-spindle coolant or carbide-grade tool life should select a different bit.

Questions about this item
Will the #7 bit with its .2010 inch diameter fit the chuck on my older 3/8 inch drill?
Yes, the #7 bit has a .2010 inch diameter which is well under the 3/8 inch maximum capacity of most standard chucks, so it will fit securely.
How can I confirm the 135 degree split point is cutting correctly on first use?
The 135 degree split point should start on contact without walking and produce short, curly chips in steel, showing it is self-centring and cutting efficiently.
Does the C23207 package include any cutting fluid or only the 1801 steam oxide bit?
The box contains the single C23207 jobber length drill bit with 1801 steam oxide finish; cutting fluid or lubricant must be purchased separately.
