What it is and who it fits

The Chicago-Latrobe 44239 is a fractional-inch jobber length drill bit made from high speed steel with a bright uncoated finish. It has a 118 degree conventional point and no coolant holes. The decimal equivalent is .6094 inches.

Who should buy it and who should not

Machinists and maintenance crews drilling mild steel, aluminium or plastic will find the general-purpose geometry reliable. Shops that require through-coolant delivery or a coated bit for abrasive alloys should look at a different tool.

The deciding specification

The drill bit size is 39/64 in and the point angle is 118 degrees. These two figures determine whether the bit matches the hole diameter and material hardness required for the job.

Questions about this item

Will the 39/64 in shank fit the chuck on my older drill press?

The jobber-length bit has a straight shank sized to the 39/64 in diameter, so any chuck that opens to at least .6094 in will hold it securely.

How can I confirm the 118 degree point is cutting correctly after I install the bit?

The conventional point should produce clean, centred holes with minimal wandering; consistent chip formation and a smooth bore indicate the 118 degree angle is working as designed.

Does the 44239 come with a case or lubricant, or do I need to buy those separately?

The box contains only the single high-speed steel drill bit; no case, coolant or coating is included, so any cutting fluid or storage must be purchased separately.
