The material of the step drill bit can affect its durability, strength, and lifespan. Understand the process by which the manufacturer creates their bits to ensure you get consistent performance from batch to batch. Look for built-in depth stop collars that prevent over-drilling and ensure accurate depth setting every time. PerformanceĬheck for features like tungsten carbide cutters that offer superior cutting performance on various materials. Also, find a drill bit that can easily be cut through hard materials such as cast iron, aluminum, stainless steel, etc. The ability to quickly adjust from hole size to hole size can save time and effort, resulting in a more efficient workflow. VersatilityĬhoose a step drill bit that can accommodate multiple drilling applications with different sizes and materials. The design should make it easy to adjust speeds and depths without stopping your drilling process or readjusting your grip. Ease of useĬonsider the ease of use of the drill bit, such as its ergonomic design, handle grip, and adjustable speed/depth settings. These coatings extend the life of the tools by improving corrosion resistance. Some drill bits feature specialized coatings that increase lubricity while drilling, resulting in better hole quality and less friction heat-up. Look for bits made from high-grade steel and features like split points and titanium-nitride coating for durability and reliability. Things To Consider Before Buying a Step Drill Bit Quality It’s important to remember that investing in a high-quality step drill bit can save you money in the long run by lasting longer and providing more precise and efficient drilling. Cheaper options can range from $5 to $20, while more expensive options can cost up to $100 or more. The cost can vary significantly depending on the brand, size, and quality. This buyer’s guide outlines all the details you need to know to make an informed decision. Each storage hole is precisely sized for accurate and quick bit selection.Ģ1 pc set includes sizes 1/16”-3.8” by 64ths and comes in rugged, heavy gauge, corrosion resistant, epoxy coated, snap lock all steel case.ġ5 pc set includes sizes 1/16”-1/2” by 32nds and comes in rugged, heavy gauge, corrosion resistant, epoxy coated, snap lock all steel case.ġ3 pc set includes sizes 1/16”-1/4” by 64ths and comes in rugged, heavy gauge, corrosion resistant, epoxy coated, snap lock all steel case.Ĥ pc large set includes sizes 9/16", 5/8", 3/4" and 1" and comes in blow mold case.ħ pc large set includes sizes 9/16" to 1" by 1/61ths and comes in blow mold case.You must consider several necessary factors when choosing a step drill bit for your application. They excel at drilling thinner and hardened metals.Ģ9 pc set includes bits from 1/16”-1/2” by 64ths and comes in a strong, lightweight, high-density plastic case that is weatherproof, waterproof and unbreakable. They are recommended for use with cast iron, brass, sheet metal, plastic, aluminum, mild steel, copper, hardened steel and even wood and composites. The three-flatted shanks reduce slippage common with keyless chucks. Bits larger than 1/2" have 1/2" shanks with 3 flats Plus, these bits virtually eliminate burrs and blowout on the exit side. They are perfect for enlarging existing holes without binding or grabbing as the bit exits the material. The 135° split point allows for fast penetration, accurate and easy starting without a center punch. The precision ground point, flutes, body, clearance and drill diameter result in the ultimate in accuracy and performance. This unique tip geometry requires less torque which creates less heat and thus increases tool life.Ĭonstructed from special Hi-Molybdenum tool steel these bits stay sharp up to 4X longer than conventional and other specialty drill bit designs. and allows for laser straight holes in metal and other materials. These Vortex-Point drill bits cut 45% faster than conventional split point drill bits. The multi-stepped tip acts like a step drill which prevents walking on curved surfaces.
