Chicago-Latrobe #7 Jobber Drill Bit
This Chicago-Latrobe 45677 drill bit is made from High Speed Steel with a black oxide finish. It features a 135 degree split point designed for accurate starting without a centre punch. The jobber length suits general-purpose drilling in metal, wood and plastic. Its decimal equivalent is .2010 inches.
Suited for general workshop and maintenance tasks
The split point geometry helps the bit start cleanly on curved or hard surfaces. Users needing a coolant-through design or a different point angle should consider other options. Buyers who require a coated bit for extended life in abrasive materials will need a different specification. This bit does not have a coolant-through hole.

Questions about this item
How much heat does the #7 TiN bit generate during extended drilling?
The 135-degree split point reduces thrust and friction, lowering heat build-up during long sessions.
What shank size does the 45677 bit need to fit my drill?
The .2010-inch diameter shank fits standard three-jaw chucks that accept wire-gauge sizes.
