Chicago-Latrobe 55437 drill bit
The Chicago-Latrobe 55437 is a Silver & Deming drill bit made from high-speed steel with a black oxide finish. It is designed for general-purpose drilling in metal, wood and plastic where a reduced shank is required. The 118-degree point angle suits a wide range of materials and handheld or stationary use.
Reduced shank fits standard chucks
The 1/2-inch reduced shank allows this 37/64-inch bit to be used in drill chucks that cannot accept larger straight shanks. This extends the capacity of a standard 1/2-inch chuck without needing a specialty holder. The black oxide finish helps retain lubricant and resist corrosion during operation.
Simple installation with common issues
Insert the shank fully into the chuck and tighten securely on the flats to prevent spin-out under load. Apply steady pressure and appropriate cutting fluid for the material to avoid overheating the high-speed steel. Common problems include dulling the 118-degree point on hard alloys or snapping the bit if side-loaded in deep holes.

Questions about this item
Should I choose the 37/64 in drill bit or a different size?
Select the 37/64 in bit when you need that exact hole diameter; other sizes in the Silver & Deming range cover different fractional increments.
What does the 118 degree point angle do in use?
The 118 degree point centres quickly in mild steel and general-purpose metal, giving a clean start without a centre punch.
How does the 1/2 reduced shank affect compatibility?
The 1/2 reduced shank fits any drill chuck that accepts 1/2 in shanks, letting you use this larger bit in standard 1/2 in capacity drills.
