Chicago-Latrobe 53458 Drill Bit
This Chicago-Latrobe 53458 drill bit is a power tool accessory designed for drilling operations requiring a 29/32 inch diameter. It suits professionals and workshops needing a specific large-size bit with a reduced shank for compatibility with standard 1/2 inch chucks.
118 Degree Point and Cobalt Material
The 118 degree point angle provides a standard cutting geometry suitable for general-purpose drilling across various materials. The machining cobalt construction offers enhanced hardness and heat resistance compared to standard high-speed steel, extending tool life in demanding applications.
Straw Bronze Finish and Reduced Shank
A straw bronze finish on the cobalt body helps identify the material grade and provides some corrosion resistance. The 1/2 inch reduced shank allows this large-diameter bit to be secured in common drill chucks, enabling use on standard drill presses and handheld drills without specialised tooling.

Questions about this item
Will the 29/32 in cobalt drill bit need resharpening or replacement after repeated use?
The 118-degree point on this Machining Cobalt bit can be resharpened multiple times; replace it once the cutting edges wear beyond practical sharpening.
What limit appears first when drilling continuously with the 53458 bit?
Heat buildup at the 118-degree point is the first limiting factor; use cutting fluid and reduce feed pressure to extend each drilling cycle.
Does the 29/32 in silver & deming drill generate noticeable heat or vibration during all-day operation?
The Machining Cobalt material and straw/bronze finish dissipate heat well, but sustained high-speed drilling will still produce significant heat at the shank and cutting edges.
