Chicago-Latrobe 52462 Drill Bit
The Chicago-Latrobe 52462 is a Silver & Deming drill bit with a 31/32 in cutting diameter and a reduced 1/2 in shank. It is manufactured from high speed steel with a black oxide finish for general-purpose machining. The 118 degree point angle suits standard drilling tasks in metal and other materials. This accessory fits power tools that accept a 1/2 in chuck capacity.
Upgrade From Smaller Shank Bits
This bit replaces standard twist drills that lack a reduced shank, allowing larger diameters to be used in a 1/2 in chuck. The jump is worth it when a 31/32 in hole is required but the tool cannot accommodate a full-size straight shank. It bridges the gap between small twist drills and dedicated large-shank tooling for occasional oversized holes. Users limited by chuck capacity gain access to this diameter without changing equipment.
Sustained Drilling Performance
High speed steel construction maintains hardness during extended cutting cycles better than carbon steel alternatives. The black oxide finish helps retain lubricant and reduces chip welding during prolonged use in steel or iron. The 118 degree point distributes cutting forces evenly, reducing tip wear when drilling repeated holes. Heat buildup is managed by the material properties rather than specialised coatings not present on this bit.

Questions about this item
What chuck size does the 31/32 in drill bit with 1/2 reduced shank require?
The 1/2 reduced shank fits any drill chuck that accepts a 1/2 inch shank diameter.
How should the 118 degree point angle bit be started to avoid walking?
Use a centre punch mark and light pressure at low speed until the 118 degree point engages the workpiece.
When should the black oxide high speed steel bit be replaced?
Replace the bit when the cutting lips show visible wear, the black oxide finish is worn away or the bit no longer cuts cleanly.
