Chicago-Latrobe 55436 118 Degree Drill

The Chicago-Latrobe 55436 is a Silver & Deming drill bit designed for general-purpose drilling tasks. Its 118-degree point angle provides reliable starting performance across a range of materials. The reduced 1/2-inch shank allows compatibility with standard drill chucks. This new accessory suits both professional workshops and DIY users.

Black Oxide Finish and High Speed Steel

The bit is manufactured from High Speed Steel for durability and wear resistance during machining operations. A black oxide finish adds corrosion protection and helps reduce friction while drilling. These material choices extend the usable life of the cutting edges. The combination supports consistent performance in metalworking applications.

Suits standard chuck drilling in metal

This drill bit fits users needing a 9/16-inch cutting diameter with a shank that fits common 1/2-inch chucks. It is not suited for buyers requiring a full-size shank for heavy-duty rigidity. Those needing specialised point geometries for hard alloys should look at alternative bit designs. The tool addresses standard metal drilling needs effectively.

Questions about this item

When will the 118-degree point on this 55436 drill bit need resharpening?

Resharpen the 118-degree point when drilling force increases noticeably or hole quality drops; high-speed steel allows repeated sharpening.

What stops a continuous drilling session first with this reduced-shank bit?

Heat buildup in the high-speed steel body limits sustained use; pause to let the bit cool before it loses temper.

How hot does the black-oxide finish get during all-day drilling?

The black-oxide surface runs hot under constant load; use cutting fluid and regular breaks to manage temperature.
