Chicago-Latrobe 45605 5/64" HSS Drill Bit
This Chicago-Latrobe 45605 jobber-length drill bit is made from high-speed steel with a black oxide finish. It suits metalworkers and maintenance technicians drilling small holes in steel, cast iron or non-ferrous alloys. The fractional 5/64 inch size matches common fastener pilot requirements.
135-degree split point limits walking on hard
The 135-degree split point reduces thrust and prevents the bit from wandering when starting a hole in harder materials. The black oxide coating aids chip flow and resists corrosion but does not add the wear resistance of a dedicated coating. Users needing higher cutting speeds or longer life in abrasive alloys should consider cobalt or carbide-tipped alternatives.

Questions about this item
What does the 5/64 inch size mean for the holes I can drill?
The 5/64 inch diameter (0.0781 decimal) produces a pilot hole suited for small screws or fine clearance work in metal, wood or plastic.
How does the 135 degree split point affect drilling performance?
The 135 degree split point centres the bit without a centre punch and reduces walking on hard surfaces, giving faster starts in steel and other materials.
