Chicago-Latrobe 47732 Jobber Drill Bit

The Chicago-Latrobe 47732 is a jobber-length drill bit with a 1/2 inch diameter and a 135-degree split point. It is made from cobalt steel for drilling into hard metals such as stainless steel. The straw-bronze finish identifies the material grade. This bit suits maintenance technicians and metal fabricators who need a durable, general-purpose cutting tool.

Installation fits standard drill chucks

The 1/2 inch shank fits directly into any drill chuck that accepts that capacity. The split-point geometry is self-centring, so the bit starts on contact without a centre punch. Cobalt steel is brittle compared with high-speed steel; excessive side pressure or high speed without coolant can snap the cutting edges. Keep the flutes clear of swarf to prevent binding and overheating.

Suited for hard-metal drilling

This bit serves shops that regularly drill stainless steel, titanium or high-strength alloys where standard bits wear quickly. It is not for buyers who need coolant-through capability for deep-hole work. It is not for users who require a reduced shank to fit smaller chucks. It is not for woodworking or masonry applications where the aggressive point angle would cause tear-out or premature wear.

Questions about this item

How can I verify the 135° split point is cutting correctly after installation?

The 135° split point should self-centre and produce clean chips without walking on the workpiece.

Does the 47732 jobber drill bit come alone or in a set with other sizes?

The listing describes a single 1/2 in jobber drill bit; no additional bits or accessories are included.

When should I choose this 1/2 in cobalt bit instead of a smaller fractional size?

Select the .5000 in diameter when the hole specification calls for exactly 1/2 inch in tough materials.
