Step Tip Drill Bits

The best step drill bit depends on the material and precision required, but M35 Cobalt step bits are widely regarded as top performers due to their heat resistance and durability when drilling metal and stainless steel. Fractional sizing options like 1/8" to 1/2" offer broad versatility for industrial and fabrication applications.

Our cobalt step tip drill bits are available in fractional sizing ranging from 1/8" to 1/2", covering the most common hole diameters needed for sheet metal, enclosures, brackets, and general fabrication work. This range allows a single bit to replace multiple standard twist drills.

These step tip drill bits are manufactured from M35 Cobalt, an alloy known for superior heat resistance and hardness compared to standard high-speed steel. This construction extends tool life and maintains cutting performance when drilling through metal, stainless steel, and other demanding materials.

Yes, while step tip drill bits are primarily designed for metal and metal fabrication, they also perform well on plastic, thin composites, and softer materials. Their graduated design makes them versatile for general maintenance and repair tasks beyond strictly metalworking applications.

A single step drill bit can produce multiple hole diameters, eliminating the need to purchase and switch between several individual twist bits. This reduces tool inventory costs, minimizes downtime from bit changes, and improves overall efficiency on the shop floor.

Yes, volume and custom pricing are available upon request, and these step tip drill bits can be purchased through our GSA MAS Contract for qualifying government and institutional buyers. Contact our team for a tailored quote based on your order quantity.
