20-Piece Jobber Length Drill Bit Set
The Chicago-Latrobe 69897 set supplies twenty high-speed steel drill bits with a TiN finish. Each bit uses a 118-degree point angle for general-purpose drilling. The jobber length format suits a wide range of portable and stationary drilling equipment.
Suited for general maintenance and fabrication
This set fits technicians and tradespeople who need a ready assortment of standard sizes for everyday metal, wood and plastic work. Buyers who require specialised point geometries, cobalt alloys or coated bits for hardened steels should look at something else.
118-degree point angle
The 118-degree point angle determines how the bit centres and cuts in common materials. It is the single specification that decides whether this set matches the drilling tasks you face.

Questions about this item
How do I install the 118° point bits from the 69897 set and what step is often missed?
Clamp the workpiece, select the correct bit from the 20-piece range, and set the drill to the proper speed for high-speed steel; the step often missed is applying cutting fluid to reduce heat and extend edge life.
What maintenance or replacement will the TiN-coated high-speed steel bits need later?
The TiN finish on the 20 bits resists wear, but once the cutting edges dull they cannot be economically re-sharpened; plan to replace individual bits or the full set when drilling performance drops.
What limit appears first when the 20-piece jobber set is used continuously?
Heat buildup in the high-speed steel body is the first limit; without pauses or coolant the 118° points lose hardness faster, so schedule cooling breaks during sustained drilling.
