Still Dealing With Cheap Drill Bits?
A good drill bit should start clean, cut smoothly and keep working when the job gets tough.
Bit Keeps Walking
Cheap tips can slip across the surface before the hole even starts.
Too Much Heat
Friction and poor chip removal can make drilling slower and harder.
Bits Wear Out Fast
Low-quality drill bits often need replacing after only a few jobs.
Why Upgrade To This Cobalt Drill Bit Set?
Built around precision, heat management and long-term durability.
135° Split-Point Tip
The precision split-point design helps the bit start where you want it instead of sliding across the surface. This can reduce the need for a center punch during many drilling jobs.
Designed To Reduce Heat
Fully ground spiral flutes help move chips away from the cutting area, helping reduce friction and heat buildup during drilling.
M35 High-Speed Steel + 5% Cobalt
Made from M35 6542 high-speed steel with 5% cobalt for increased hardness, heat resistance and durability compared with standard HSS drill bits.
One Set For Multiple Jobs
The 6-piece set covers common sizes from 3mm through 8mm, making it easy to keep the right size ready for everyday projects.
Cleaner, More Professional Results
The sharp cutting edges are designed to create smoother starts and more controlled drilling performance for both DIYers and experienced users.
Built For Repeated Use
The treated surface and corrosion-resistant finish help protect the drill bits during storage and repeated workshop use.
One Small Upgrade. A Better Toolbox.
Instead of keeping multiple basic drill bit sets for different projects, keep a compact cobalt set ready for demanding drilling jobs.
