Chicago-Latrobe 50824 Cobalt Drill Bit

The Chicago-Latrobe 50824 is a screw machine drill bit sized at 27/64 in with a 135 degree split point. It is made from cobalt steel and finished in a straw colour. The bit suits machinists and maintenance crews drilling precise holes in tough alloys.

Split point geometry reduces walking

The 135 degree split point centres the cut immediately without a centre punch. Cobalt construction resists heat during high-speed drilling. Right-hand cutting direction matches standard drill presses and handheld drivers. No coolant-through channels are present.

Verify shank fit and material needs

Confirm your chuck accepts a straight shank of this diameter before ordering. The bit is not designed for coolant-fed spindles. Buyers needing a coated flute or a left-hand cutting version should look elsewhere. Decimal equivalent is .4219 for reference.

Questions about this item

Will the cobalt material on this 27/64 in drill bit need resharpening or replacement after heavy use?

The cobalt construction resists wear longer than standard steel, but the 135 degree split point will eventually dull and require professional resharpening or replacement.

What limit appears first when drilling continuously with this 135 degree split point bit?

Heat buildup at the cutting edges becomes the primary limit during sustained drilling since the bit has no coolant-through design.

How much heat and noise does this right hand cutting drill bit produce during all day operation?

Expect significant heat at the 0.4219 in cutting diameter with no internal cooling; noise level matches typical high speed steel drilling in metal.
