Chicago-Latrobe 41798 13PC Drill Bit Set

The Chicago-Latrobe 41798 set contains 13 jobber length drill bits manufactured from High Speed Steel with a Titanium Nitride finish. Each bit features a 135 degree point angle designed for heavy-duty drilling applications. The set is supplied new and ready for workshop use.

Suits general metal drilling.

These bits suit mechanics and fabricators drilling common ferrous and non-ferrous metals where a 135 degree split point reduces walking. Buyers who need cobalt alloy bits for hardened steels or specific diameter ranges outside this assortment should look at alternative tooling.

135 degree point angle defines cutting action

The 135 degree point angle is the critical specification determining how the bits engage material and clear chips in heavy-duty work. Verify that this geometry matches the requirements of your drilling operations before purchase.

Questions about this item

Will the TiN coating on the 135-degree points need re-sharpening after heavy use?

The TiN finish reduces wear on the 135-degree split points, extending edge life in high-speed steel; re-sharpening is only needed when cutting performance drops.

What limits continuous drilling with this 13-piece high-speed steel set?

Heat buildup in the jobber-length bits is the first limit during sustained drilling; use cutting fluid and pause to let the high-speed steel cool.

How much heat and noise do the TiN-coated bits generate in all-day drilling?

The 135-degree points cut efficiently, lowering friction and heat versus standard bits; noise comes from the drill motor, not the bits themselves.
