USA Made Titanium Step Drill Bit 1/4"-3/4" (9 Steps)

USA MADE TITANIUM STEP DRILL BIT 1/4"–3/4" – 9 STEPS

Drill and enlarge multiple hole sizes with one USA-made industrial-quality step drill bit instead of stopping to change bits. This 9-step design produces hole sizes from 1/4" through 3/4", making it a versatile choice for fabrication, maintenance, electrical work, automotive work, and other professional drilling applications.

The bit is manufactured from heat-treated M2 high-speed steel with a titanium coating that adds hardness and wear resistance for longer service life and faster drilling. Chamfered steps allow the operator to progressively work through each diameter for greater control and accuracy, while the self-centering 135° split point starts on contact to reduce wobbling and eliminate the need for a center-punch hole in many applications. A double-flute design promotes fast chip removal and heat evacuation for a cooler drilling operation and extended bit life.

Other machines with a compatible chuck can also be used. Match the tool’s drilling capacity and speed to your material and hole size, and turn hammer action off on hammer drills.

Safety Tips

• Wear eye protection and appropriate hearing and respiratory protection. Keep gloves and loose clothing away from rotating parts.
• Secure or clamp the workpiece before drilling.
• Keep the bit square to the work surface for a controlled, accurate cut.
• Allow the chamfered steps to progressively enlarge the hole rather than forcing the bit.
• Use steady pressure and let the cutting edges do the work.
• Select speed according to the material and hole diameter being drilled.
• Use an appropriate cutting lubricant when drilling metals.
• Stop the tool before clearing chips; use a brush, not your hands.
• Do not use hammer action when drilling with a hammer drill/driver.
• Secure the shank according to the tool’s chuck instructions and check retention before drilling.
