HSS Step Drill Bit (Titanium Finish)

Perfect for drilling and enlarging different sized holes without changing the drill bit. Use one single bit for multiple holes
Ideal for creating burr-free holes in sheet metal, plastic, copper, wood, aluminum, and carbon fiber
Industrial Quality for professionals
Heat-treated, M2 high speed steel body material with titanium coating
Titanium coating adds extra hardness and wear resistance to make the drill bit last longer and drill faster
Chamfered steps allow the user to slowly progress through multiple sizes and drill up to the desired size step by step for greater accuracy
Self-centering 135° split point tip prevents “wobbling” by eliminating center punch holes and starting instantly on contact
Double flute design ensures quick chip removal, removes heat for a “cooler drilling operation”, and extends bit life
Can come with carded packaging which is perfect for distributors and resellers
