Chicago-Latrobe 54126 11pc Cobalt Drill Bit Set

This Chicago-Latrobe 54126 set contains 11 cobalt steel jobber length drill bits. The 135 degree point angle is designed for efficient drilling in hard metals. A straw bronze finish helps identify the cobalt construction. It suits professionals and DIY users needing durable bits for stainless steel and alloy work.

Users needing larger diameters

Buyers requiring drill bit diameters not included in this 11 piece assortment should look elsewhere. Those needing specialised point geometries for materials like wood, glass or masonry will find this set unsuitable. Users who prefer high speed steel for general purpose drilling in softer materials may want a different composition.

Questions about this item

How long do the 135° cobalt bits hold their edge when drilling hardened steel all day?

The 135° split-point geometry on cobalt steel reduces walking and keeps the cutting lips sharper longer than standard high-speed steel bits in hardened steel.

Do the 11 bits in the 54126 set run cooler than black-oxide bits during continuous drilling?

Cobalt alloy dissipates heat faster than black-oxide HSS, so the bits stay cooler and the straw-bronze finish resists galling during extended use.
