Chicago-Latrobe 57853 60-piece 135° cobalt jobber drill set pneumatic accessory

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.
