Chicago-Latrobe 50862 Cobalt Drill Bit
This Chicago-Latrobe 50862 drill bit is a #7 size screw machine bit made from cobalt steel. It features a 135-degree split point designed for drilling in metal. The decimal equivalent is .2010 inches. It is a new power tool accessory supplied without coolant-through capability.
Suited for metal drilling with split-point start
This bit suits machinists and technicians drilling precise holes in steel and other hard alloys where the split point reduces walking. The right-hand cutting direction matches standard drill presses and hand drills. Buyers needing coolant-through feed for deep-hole chip evacuation or a different point angle for specialised materials should look at other tooling.
135-degree split point on cobalt steel
The defining specification is the 135-degree split point ground on cobalt steel. This combination determines how the bit centres itself and withstands heat in tough alloys. Verify that the .2010 diameter matches the hole size required for your application before purchasing.

Questions about this item
What chuck size does the #7 0.2010 inch drill bit require?
The bit has a 0.2010 inch diameter shank, so it fits any standard drill chuck that accepts that size.
How do I start the hole correctly with the 135 degree split point?
Apply steady pressure on centre punch mark; the 135 degree split point self-centres without a pilot hole.
When should I replace this cobalt steel bit?
Replace when the cutting lips wear unevenly or the straw-coloured surface turns blue from overheating.
