Chicago-Latrobe 57853 60-Piece Cobalt Drill Set
This Chicago-Latrobe 57853 set contains 60 jobber-length drill bits made from machining cobalt with a straw-bronze finish. Each bit features a 135-degree point angle designed for heavy-duty drilling applications. The comprehensive assortment suits professional workshops and serious DIY users who need a wide range of sizes in one package.
Suited for high-volume metalwork.
Mechanics and fabricators who regularly drill stainless steel, cast iron or other hard alloys will benefit from the cobalt construction and split-point geometry. The 60-piece count covers extensive sizing needs for production or maintenance tasks. Buyers who only need a few bits for rare wood or plastic jobs should look at smaller, less specialised sets.
135-degree split point reduces walking on hard
The 135-degree point angle is the critical specification that determines performance in tough metals, centring the bit without a centre punch and lowering thrust requirements. Cobalt substrate maintains hardness at elevated temperatures generated during heavy-duty drilling. Verify that your application demands this geometry before purchasing.

Questions about this item
Will these 135° cobalt bits work in my older 3/8" chuck drill?
Yes, jobber-length shanks fit standard 3/8" chucks; the 135° split point reduces walking on hard metal.
How can I verify the 135° point angle is correct after unpacking?
Inspect each tip — the split point should show a distinct 135° angle and straw/bronze finish.
Does the 57853 set include a case or do I need a separate index?
The 60-piece set ships in a fitted metal index case; no extra storage purchase is required.
