Premium M35 Cobalt Drill Bit Set

This 13-piece Olympia Tools set is made from M35 HSS cobalt steel for superior heat resistance and durability when drilling through hard metals. It is designed for professional craftsmen and serious DIY enthusiasts who need reliable performance on stainless steel, iron, steel, copper, and aluminum. The industrial-grade straight shank ensures a secure fit in standard drill chucks for stable operation.

Size Range and Material Limits

The set includes 13 precisely marked bits ranging from 1/16 to 1/4 inch, covering common diameters for metalworking tasks. The M35 cobalt construction provides the headroom needed for tough alloys like stainless steel where standard bits wear quickly. It runs out when a project demands sizes larger than 1/4 inch or requires specialised geometries such as reduced-shank or extra-length bits for deep holes.

Organised Storage Case

A sturdy blue case with labeled size compartments keeps every bit identified, protected, and ready for transport. This organisation eliminates time spent searching for the correct diameter and prevents damage to the cutting edges during storage. The case turns a loose collection of bits into a complete, portable system that stays orderly on a jobsite or in a home workshop.

Questions about this item

Will the 1/16-inch and 1/4-inch M35 cobalt bits fit the chuck on my older corded drill?

The straight shank design fits standard drill chucks, so both the smallest and largest bits in the 13-piece set will seat securely in an older corded drill.

How can I verify the bits are cutting cleanly in stainless steel after I start using them?

Clean, accurate holes without walking or excessive heat buildup show the M35 cobalt geometry is performing as intended on hard metals.

Does the sturdy blue case come with the set or do I need to buy a separate organizer?

The 13-piece set includes a sturdy blue storage case with labeled compartments for each bit size, so no separate organizer is required.
