Chicago-Latrobe 46629 Jobber Drill Bit

The Chicago-Latrobe 46629 is a jobber length drill bit sized 29/64 inch with a 135 degree split point. It is made from cobalt steel for drilling hard metals such as stainless steel and titanium alloys. This fractional inch bit suits professional mechanics and maintenance technicians who need precise holes in tough materials.

135 Degree Split Point Cobalt Construction

The 135 degree split point design reduces walking and starts the cut immediately without a centre punch. Cobalt material resists heat and wear better than standard high speed steel during extended drilling sessions. The straw bronze finish identifies the cobalt grade and provides some lubricity. The straight shank fits standard three jaw drill chucks and quick change adapters used in daily shop work.

Check Chuck Capacity And Material Compatibility

Verify your drill chuck accepts a 29/64 inch shank before ordering. Confirm the workpiece material matches cobalt capabilities for best results. This bit has no coolant holes so external lubrication or peck drilling is required for deep holes. Buyers who need coolant through tooling or smaller fractional sizes should consider other options.

Questions about this item

What does the 135 degree split point mean for drilling?

The 135 degree split point reduces walking and starts holes accurately in metal without a centre punch.

What shank size fits this 29/64 inch jobber bit?

The shank diameter matches the 29/64 inch drill size, so it fits any chuck that accepts .4531 inch or larger.

How do I use this cobalt bit without overheating it?

Run at lower RPM with steady pressure and cutting oil; the cobalt material resists heat but still needs lubrication to prevent premature wear.
